In iOS 8 I am having problem capturing images from camera till now I am using this code for
UIImagePickerController *controller=[[UIImagePickerController alloc] init];
controller.videoQuality=UIImagePickerControllerQualityTypeMedium;
controller.delegate=(id)self;
controller.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentViewController:controller animated:YES completion:nil];
But in iOS 8 I am getting this:
Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.
I have tried with the solution provided by This Post with
#property (strong,nonatomic)UIImagePickerController *controller;
_controller=[[UIImagePickerController alloc] init];
_controller.videoQuality=UIImagePickerControllerQualityTypeMedium;
_controller.delegate=(id)self;
_controller.sourceType=UIImagePickerControllerSourceTypeCamera;
_[self presentViewController:controller animated:YES completion:nil];
and this
...
controller.modalPresentationStyle=UIModalPresentationFullScreen;
or
controller.modalPresentationStyle=UIModalPresentationCurrentContext;
...
and this
double delayInSeconds = 0.1;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
[self presentViewController:controller animated:YES completion:nil];
});
and this
[self presentViewController:controller animated:YES completion:NULL];
and this
[self presentViewController:controller animated:YES completion:^{
}];
any idea?
I'm pretty sure this is just a bug in iOS 8.0. It's reproducible with the simplest of POC apps that does nothing more than attempt to present a UIImagePickerController like you're doing above. Furthermore, there's no alternative pattern to displaying the image picker/camera, to my knowledge. You can even download Apple's Using UIImagePickerController sample app, run it, and it will generate the same error out of the box.
That said, the functionality still works for me. Other than the warning/error, do you have issues with the functioning of your app?
I was struggling with this issue for several hours, i have read every relevant topic and found out that the error was caused because under the privacy settings of my device, the camera access to my app was blocked!!! I have never denied access to camera and i don't know how it was blocked but that was the problem!
I don't have enough reputation points to comment on #greg's answer above, so will add my observations here. I have a Swift project for both iPad and iPhone. I have a method inside my main view controller (relevant bit below). When I test this on a phone, everything works properly and no warnings are generated. When I run it on an iPad, everything works properly but I see the warning about snapshotting the view. The interesting bit, however, is that when I run on an iPad without using the popover controller, everything works properly with no warning. Unfortunately, Apple mandates that the image picker must be used within a popover on iPad, if the camera is not being used.
dispatch_async(dispatch_get_main_queue(), {
let imagePicker: UIImagePickerController = UIImagePickerController();
imagePicker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum;
imagePicker.mediaTypes = [kUTTypeImage];
imagePicker.allowsEditing = false;
imagePicker.delegate = self;
if(UIDevice.currentDevice().userInterfaceIdiom == .Pad){ // on a tablet, the image picker is supposed to be in a popover
let popRect: CGRect = buttonRect;
let popover: UIPopoverController = UIPopoverController(contentViewController: imagePicker);
popover.presentPopoverFromRect(popRect, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Up, animated: true);
}else{
self.presentViewController(imagePicker, animated: true, completion: nil);
}
});
I ran into this after calling UIImagePickerController presentViewController: from the callback to a UIAlertView delegate. I solved the issue by pushing the presentViewController: call off the current execution trace using dispatch_async.
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
dispatch_async(dispatch_get_main_queue(), ^{
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
if (buttonIndex == 1)
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
else
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController: imagePickerController
animated: YES
completion: nil];
});
}
I had this issue when animating some views and the app would go into background mode and come back. I handled it by setting a flag isActive. I set it to NO in
- (void)applicationWillResignActive:(UIApplication *)application
and YES in
- (void)applicationDidBecomeActive:(UIApplication *)application
and animate or not animate my views accordingly. Took care of the issue.
I had this with an UIAlertControllerStyleActionSheet giving the user the option to take a photo with the camera or use one from library.
I tried a symbolic breakpoint on the error message
That showed me the error is produced by the intern use of a UICollectionView during presentation
[self presentViewController:alert animated:YES completion:nil];
I fixed this by explixitly setting the frame before presenting
[alert setPreferredContentSize: alert.view.frame.size];
Here is the complete methode that is working without the error
-(void)showImageSourceAlertFromSender:(id)sender{
UIButton *senderButton = (UIButton*)sender;
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cameraAction = [UIAlertAction actionWithTitle:#"Camera" style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action) {
[self takePhoto];
}];
UIAlertAction *libraryAction = [UIAlertAction actionWithTitle:#"Library" style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action) {
[self selectPhotoFromLibraryFromSender:sender];
}];
[alert addAction:cameraAction];
[alert addAction:libraryAction];
alert.popoverPresentationController.delegate = self;
alert.popoverPresentationController.sourceRect = senderButton.frame;
alert.popoverPresentationController.sourceView = self.view;
[alert setPreferredContentSize: alert.view.frame.size];
[self presentViewController:alert animated:YES completion:^(){
}];}
You can silence the "Snapshotting a view" warning by referencing the view property before presenting the view controller. Doing so causes the view to load and allows iOS render it before taking the snapshot.
UIAlertController *controller = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
controller.modalPresentationStyle = UIModalPresentationPopover;
controller.popoverPresentationController.barButtonItem = (UIBarButtonItem *)sender;
... setup the UIAlertController ...
[controller view]; // <--- Add to silence the warning.
[self presentViewController:controller animated:YES completion:nil];
For anyone that is seeing an issue with a black preview after image capture, hiding the status bar after the UIPickerController is shown seems to fix the issue.
UIImagePickerControllerSourceType source = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] ? UIImagePickerControllerSourceTypeCamera : UIImagePickerControllerSourceTypeSavedPhotosAlbum;
UIImagePickerController *cameraController = [[UIImagePickerController alloc] init];
cameraController.delegate = self;
cameraController.sourceType = source;
cameraController.allowsEditing = YES;
[self presentViewController:cameraController animated:YES completion:^{
//iOS 8 bug. the status bar will sometimes not be hidden after the camera is displayed, which causes the preview after an image is captured to be black
if (source == UIImagePickerControllerSourceTypeCamera) {
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}
}];
I found the same issue and tried everything. I have two different apps, one in objective-C and one in swift - both have the same problem. The error message comes in the debugger and the screen goes black after the first photo. This only happens in iOS >= 8.0, obviously it is a bug.
I found a difficult workaround. Shut off the camera controls with imagePicker.showsCameraControls = false and create your own overlayView that has the missing buttons. There are various tutorials around how to do this.
The strange error message stays, but at least the screen doesn't go black and you have a working app.
This might be a bug of built-in ImagePickerController. My code is working, but occasionally crashes on iPhone 6 Plus.
I've tried all solutions suggested by other answers but there were no luck. Problem finally solved after switching to JPSImagePickerController.
I've tried everything, my problem was that the image picker for the camera and photo library disappeared right after they showed. I solved it with the following line (swift)
imagePicker.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext

If we are using the UIImagePickerController as a property, then this warning will disappear. xcode assume that we are not using the result from the UIImagePickerController , if we are instantiating the UIImagePickerController within a function.
Calling this method worked for me. Place it after presenting your view.
[yourViewBeingPresented.view layoutIfNeeded];
I also encounter the same problem and I resolved it by checking if the camera is available:
BOOL cameraAvailableFlag = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
if (cameraAvailableFlag)
[self performSelector:#selector(showcamera) withObject:nil afterDelay:0.3];
I have came across with this issue. When we call the camera and release the views produced this issue. For an example call an camera and set view nil in viewDidDisappear method this error will come since there is not callback for camera event. Make sure about this case too for this error.
I got the same bug,getting bellow message in console while opening camera.
'Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.'
For me problem was with the Bundle display name in Info.plist file.it was empty some how,i put my app name there and now it working fine.i did't received any camera permission alert because of empty Bundle display name.it blocked the view from rendering.
the problem was't with view but by presenting it without a permission.you can check it on settings-->privacy-->Camera,if your app not listed there problem might be same.
I'm using Phonegap, but this thread keeps coming as the first one when Googling about the error message.
For me this issue went away by defining the imagetype to PNG.
encodingType : Camera.EncodingType.PNG
So the whole line being:
navigator.camera.getPicture(successFunction, failFunction, { encodingType : Camera.EncodingType.PNG, correctOrientation:true, sourceType : Camera.PictureSourceType .PHOTOLIBRARY, quality: 70, allowEdit : false , destinationType: Camera.DestinationType.DATA_URL});
Your mileage may vary, but that did the trick for me.
Alternatively, consider using drawViewHierarchyInRect:
Swift:
extension UIImage{
class func renderUIViewToImage(viewToBeRendered: UIView) -> UIImage
{
UIGraphicsBeginImageContextWithOptions(viewToBeRendered.bounds.size, true, 0.0)
viewToBeRendered.drawViewHierarchyInRect(viewToBeRendered.bounds, afterScreenUpdates: true)
viewToBeRendered.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let finalImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return finalImage
}
}
Objective-C:
- (UIImage *)snapshot:(UIView *)view
{
UIGraphicsBeginImageContextWithOptions(view.bounds.size, YES, 0);
[view drawViewHierarchyInRect:view.bounds afterScreenUpdates:YES];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}

In my case ( XCode 7 and iOS 9 ), I use UINavigationController "hidden", so Ihave to add UINavigationControllerDelegate to present camera or roll and it work like it is supposed to! And pickerControllerDelegate.self doesn't display error either!
I developed test application on iOS 7 that pick the music from music library using MPMediaPickerController.
But when I present the media picker controller,it shows empty screen.
This is the code
(void) pickSong
{
MPMediaPickerController *mediaPicker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
mediaPicker.delegate = self;
mediaPicker.allowsPickingMultipleItems = NO;
mediaPicker.prompt = NSLocalizedString(#"Select Your Favourite Song!", nil);
[mediaPicker loadView];
[self.navigationController presentViewController:mediaPicker animated:YES completion:nil];
}
#pragma mark - MPMediaPickerController delegate
(void) mediaPicker:(MPMediaPickerController *) mediaPicker2 didPickMediaItems:(MPMediaItemCollection *) mediaItemCollection {
[self dismissViewControllerAnimated:YES completion:nil];
MPMediaItem *mediaItem = [[mediaItemCollection items] objectAtIndex:0];
self.item.soundName = [mediaItem valueForProperty:MPMediaItemPropertyTitle];
self.item.soundUrl = [[mediaItem valueForProperty:MPMediaItemPropertyAssetURL] absoluteString];
}
(void) mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker{
[self dismissViewControllerAnimated:YES completion:NULL];
}
Please help me out.
This is an iOS bug, but it only occurs when running a 32 bit build on a 64 bit (A7) device (Only iPhone 5S for now). To work around it, add a 64 bit architecture to your app. (Open build settings in xcode, and change Architecture from $ARCHS_STANDARD to $ARCHS_STANDARD_INCLUDING_64_BIT.) You will then probably need to fix a number of compile, link and runtime issues. See Apple's 64-Bit Transition Guide.
Seems like there is a bug in ios7 where it doesn't like to be presented inside a uinavigation controller - try presenting it directly from a view controller.
I had the same problem and for me the solution was a combination of two of the solutions presented here. First I had to convert my app to be 64-bit ready by changing Architectures to "standard... (including 64-bit)". Once I corrected all the warnings that caused, I had to change the MPMediaPickerController to be presented modally rather than on the navigation stack:
- (IBAction)didSelectMusicPicker:(id)sender {
MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
picker.delegate = self;
picker.allowsPickingMultipleItems = YES;
picker.prompt = NSLocalizedString (#"Add songs to play", "Prompt in media item picker");
//[self.navigationController pushViewController:picker animated:YES];
[self presentViewController:picker animated:TRUE completion:NULL];
}
Of course, I also needed to change mediaPicker:didPickMediaItems: and mediaPickerDidCancel: to use dismissViewControllerAnimated. Once all that was fixed, the picker worked as expected on both iPhone 4 and iPhone 5S running iOS 7.
a thought: is the presented screen completely empty, or are you getting the navigation bar at the bottom but with no tracks listed? I've noticed that as of iOS 7 the picker now defaults to opening to the Playlist tab (it used to open to Albums, if I recall)… if you have no playlists on the device that would account for the empty screen…
I can see the list of songs and select the songs. But I cannot dismiss the view controller on pressing "Done". I've tried PresentViewController since Modal controller is deprecated.
- (IBAction) showMediaPicker: (id) sender {
picker =
[[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAnyAudio];
picker.delegate = self;
picker.allowsPickingMultipleItems = YES;
picker.prompt = NSLocalizedString (#"AddSongsPrompt", #"Prompt to user to choose some songs to play");
[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated:YES];
[self.picker removeFromParentViewController];
[self presentViewController:picker animated:YES completion:nil];
// [picker release];
}
// Responds to the user tapping Done after choosing music.
- (void) mediaPicker: (MPMediaPickerController *) mediaPicker didPickMediaItems: (MPMediaItemCollection *) mediaItemCollection {
[self.picker removeFromParentViewController];
[self dismissViewControllerAnimated:YES completion:nil];
//
[self.delegate updatePlayerQueueWithMediaCollection: mediaItemCollection];
// [self.mediaItemCollectionTable reloadData];
// [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque animated:YES];
}
I've tried RemovefromSuperview also, nothing seems to work. I'm testing this on an iPhone 6 simulator and an iPhone 5 with iOS 8.1.3.
Anyone???
I also have the same problem before. But I found out just need to restart the device after upgrade. The music picker appear again.
I am currently writing an iOS app and do not like the speed at which the UIImagePickerController disappears.
I call [self dismissModalViewControllerAnimated:YES]; the instant I am inside of - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info; And yet the imagePicker takes several moments to disappear, long enough on some photos that the app appears frozen to the user.
One solution I thought of was to just throw up a UIActivityIndicator infront of the UIImagePickerController but I have not figured out a way to accomplish this.
Thank you!
Edit: Any tips on how to save UIImages faster would help too I believe. Such as a way to do it asynchronously.
There is a great tutorial on doing this with grand central dispatch and code blocks by Ray Wenderlich :
http://www.raywenderlich.com/1888/how-to-create-a-simple-iphone-app-tutorial-part-33
You can also do this with a job queue and performSelector:onThread:withObject:waitUntilDone: if blocks are scary to you.
Basically, the idea is to do the least amount of real work on the main thread, because that's where the UI is drawn. Below is RW's solution, with the status part commented out. That's where you put an activity indicator.
- (IBAction)addPictureTapped:(id)sender {
if (self.picker == nil) {
// 1) Show status
//[SVProgressHUD showWithStatus:#"Loading picker..."];
// 2) Get a concurrent queue form the system
dispatch_queue_t concurrentQueue =
dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
// 3) Load picker in background
dispatch_async(concurrentQueue, ^{
self.picker = [[UIImagePickerController alloc] init];
self.picker.delegate = self;
self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
self.picker.allowsEditing = NO;
// 4) Present picker in main thread
dispatch_async(dispatch_get_main_queue(), ^{
[self.navigationController presentModalViewController:picker animated:YES];
[SVProgressHUD dismiss];
});
});
} else {
[self.navigationController presentModalViewController:picker animated:YES];
}
}
I want to record a video with UIImagePickerController. My Problem is that the method [imagePickerController startVideoCapture]; always returns 0. I am testing the application with an iPhone 4S running iOS 5.1. Could somebody please help me with this:
- (IBAction)playButtonPushed:(id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIView *videoView = self.videoViewController.view;
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] >init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.mediaTypes = [[NSArray alloc] initWithObjects: (NSString >*)kUTTypeMovie, nil];
imagePickerController.showsCameraControls = NO;
imagePickerController.toolbarHidden = NO;
imagePickerController.wantsFullScreenLayout = YES;
imagePickerController.allowsEditing = YES;
imagePickerController.videoQuality = UIImagePickerControllerQualityTypeMedium;
imagePickerController.videoMaximumDuration = 30;
[imagePickerController startVideoCapture];
imagePickerController.cameraViewTransform = > CGAffineTransformScale(self.imagePickerViewController.cameraViewTransform, CAMERA_TRANSFORM, CAMERA_TRANSFORM);
imagePickerController.delegate = self;
[self.imagePickerViewController setCameraOverlayView:videoView];
NSLog(#"%s videoCapture: %d", __PRETTY_FUNCTION__, [imagePickerController > startVideoCapture]
);
[self presentModalViewController:imagePickerViewController animated:YES];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSLog(#"didFinishPickingMediaWithInfo");
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
NSLog(#"Cancel");
}
I had the same problem and Apple's documentation didn't help. That's because they missed to mention that startVideoCapture() can return false if you haven't set the capture mode to .video like this:
picker.cameraCaptureMode = .video
This worked for me and I'm able to capture videos now.
If im not mistaken, the "startVideoCapture" method is a bool
Taken straight from apple documentation:
startVideoCapture
Starts video capture using the camera specified by the UIImagePickerControllerCameraDevice property.
- (BOOL)startVideoCapture
Return Value
YES on success or NO on failure. This method may return a value of NO for various reasons, among them the following:
Movie capture is already in progress
The device does not support movie capture
The device is out of disk space
Discussion
Use this method in conjunction with a custom overlay view to initiate the programmatic capture of a movie. You can take more than one movie without leaving the interface, but to do so requires you to hide the default image picker controls.
Calling this method while a movie is being captured has no effect. You must call the stopVideoCapture method, and then wait until the associated delegate object receives an imagePickerController:didFinishPickingMediaWithInfo: message, before you can capture another movie.
Calling this method when the source type of the image picker is set to a value other than UIImagePickerControllerSourceTypeCamera results in the throwing of an NSInvalidArgumentException exception.
If you require additional options or more control over movie capture, use the movie capture methods in the AV Foundation framework. Refer to AV Foundation Framework Reference.
Availability
Available in iOS 4.0 and later.
Declared In
UIImagePickerController.h
stopVideoCapture
Stops video capture.
- (void)stopVideoCapture
Discussion
After you call this method to stop video capture, the system calls the image picker delegate’s imagePickerController:didFinishPickingMediaWithInfo: method.
Availability
Available in iOS 4.0 and later.
Declared In
UIImagePickerController.h
Think you need to call the startVideoCapture method after calling presentModalViewController:animated: and not before.
You probably also need a short delay (<1s?) after the UIImagePickerController has been presented on-screen and the animation has stopped, then call startVideoCapture, otherwise there are times where it will not start recording.
I had exactly the same problem. AndyV has it right, the recording won't start until the picker has been presented. I spent a lot of time trying to introduce a delay with sleep, but the simplest solution is to start a timer after displaying the picker using
NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval: 1.0 target:self selector:#selector(startRecording) userInfo:nil repeats: NO];
Then ..
- (void)startRecording
{
BOOL result = [picker startVideoCapture];
}
I'd like to know how to open the camera inside of a pre-defined frame (not the entire screen). When the view loads, I have a box, and inside it, I want to display what the camera sees. I don't want to snap a picture, just basically use the camera as a viewfinder. I have searched this site and have not yet found what I'm looking for. Please help.
Thanks!

Update 1:
Here is what I have tried so far.
1.) I added UIImageView to my xib.
2.) Connect the following outlet to the UIImageView in IB
IBOutlet UIImageView *cameraWindow;
3.) I put the following code in viewWillAppear
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
NSLog(#"viewWillAppear ran");
}
But this method does not run, as evident by the absence of NSLog statement from my console. Please help!
Thanks,
Thomas
Update 2:
OK I got it to run by putting the code in viewDidLoad but my camera still doesn't show up...any suggestions? Anyone....? I've been reading the UIImagePickerController class reference, but am kinda unsure how to make sense of it. I'm still learning iPhone, so it's a bit of a struggle. Please help!
- (void)viewDidLoad
{
[super viewDidLoad];
// Create a bool variable "camera" and call isSourceTypeAvailable to see if camera exists on device
BOOL camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
// If there is a camera, then display the world throught the viewfinder
if(camera)
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
// Since I'm not actually taking a picture, is a delegate function necessary?
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
NSLog(#"Camera is available");
}
// Otherwise, do nothing.
else
NSLog(#"No camera available");
}
Thanks!
Thomas
Update 3:
A-HA! Found this on the Apple Class Reference.
Discussion
The delegate receives notifications
when the user picks an image or movie,
or exits the picker interface. The
delegate also decides when to dismiss
the picker interface, so you must
provide a delegate to use a picker. If
this property is nil, the picker is
dismissed immediately if you try to
show it.
Gonna play around with the delegate now. Then I'm going to read on wtf a delegate is. Backwards? Whatever :-p
Update 4:
The two delegate functions for the class are
– imagePickerController:didFinishPickingMediaWithInfo:
– imagePickerControllerDidCancel:
and since I don't actually want to pick an image or give the user the option to cancel, I am just defining the methods. They should never run though....I think.
add
[picker
dismissModelViewControllerAnimated:YES];
to delegate method bodies.
It will dismiss the view.
