I am implementing a basic application that which allows to select a play list from music with in the application. I make it. But my problem is it is showing directly Music tab directly. But as per my requirements I need to show the playlist tab when the user takes to that view. Following is my code,
MPMediaPickerController *picker =
[[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
picker.delegate = self;
picker.allowsPickingMultipleItems = YES;
picker.prompt = NSLocalizedString (#"Select any song from the list", #"Prompt to user to choose some songs to play");
// The media item picker uses the default UI style, so it needs a default-style
// status bar to match it visually
[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES];
[self presentModalViewController: picker animated: YES];
[picker release];
-(IBAction)btnSelectSong:(id)sender
{
MPMediaPickerController *picker =
[[MPMediaPickerController alloc]
initWithMediaTypes: MPMediaTypeAnyAudio];
[picker setDelegate: self];
[picker setAllowsPickingMultipleItems: YES];
picker.prompt =
NSLocalizedString (#"Add songs to play",
"Prompt in media item picker");
[self presentModalViewController: picker animated: YES];
}
opening in the playlist section of MPMediaPickerController is not possible according to Apple's documentation
as already i answered here:
You will need to implement your own picker, using media queries (by song ,by artist, etc).

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.
Iam using the following code for taking the picture automatically from IPAD front camera:
UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
imgPkr.delegate = self;
imgPkr.cameraDevice=UIImagePickerControllerCameraDeviceFront;
[self presentModalViewController:imgPkr animated:YES];
imgPkr.showsCameraControls = NO;
[imgPkr takePicture];
But this code Dont take any picture and dont call the delegate:
-(void)imagePickerController:(UIImagePickerController*)picker
didFinishPickingMediaWithInfo:(NSDictionary*)info
Any idea what is wrong with the code
My first guess is that [imgPkr takePicture]; is being called before the picker is done being presented. Try it like this:
UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;
imgPkr.delegate = self;
imgPkr.cameraDevice=UIImagePickerControllerCameraDeviceFront;
[self presentModalViewController:imgPkr animated:YES];
imgPkr.showsCameraControls = NO;
[self performSelector:#selector(takePicture) withObject:self afterDelay:1.0];
OR
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(takePicture)
name:AVCaptureSessionDidStartRunningNotification
object:nil];
&
- (void)takePicture
{
[imgPkr takePicture];
}
I bet that you get a message in your logs saying that
UIImagePickerController: ignoring request to take picture; camera is
not yet ready.
This is a common problem because the underlying capture session needs some time to start, so you just have to be sure that the camera is ready to take a picture and then call takePicture method. Now, a way to get notified is explained in detail in my answer here: How to know if iPhone camera is ready to take picture?
Note though that this method will work on iOS5+ (there is a bug in older versions that prevents the system notifications for this event, contrary to what is described in the documentation). I hope that this helps.
another way to wait for camera ready until take picture is completion block ->
[self presentViewController:imagePicker animated:YES
completion:^ {
[imagePicker takePicture];
}];

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.

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'm trying to reproduce a Similar Media Picker that is like the one in Pages. Within a UIPopoverController There is a UISegmentedControl that selects different media Types. One of the SegmentedControls I have is Labeled Images. I want to be able to select that Segment and have the view below present the ImagePicker.
I'm Close. I have a few issues. When presenting the VC, I get:
I get the Following in the Debugger:
UIStatusBarStyleBlackTranslucent is not available on this device. Not sure where that is coming from. I've tried with and without:
imagePicker.modalInPopover = YES;
imagePicker.modalPresentationStyle = UIModalPresentationCurrentContext;
Though I still cannot get it to work Right. It Presents just fine. I see the UISegmentedControl I see my other Media Pages, I click the Image segment and I see the ImagePicker, Title is 'Photos' Has a Cancel Button I need to get rid of, and shows the two Albums I have on the device.
If I tap anywhere in the TableView (on an album or not), the two Albums go away. The NavBar and Cancel button are still there, though no Albums anymore. Tapping an Album Highlights the Row, though does not show the Images within the Album.
The other odd part of my code is that the Delegate for the Image Picker is the VC that Presented the UIPopoverController. Not sure if that plays into it. When I do hit the Cancel Button, I get:
-[PLUILibraryViewController performSelector:withObject:withObject:]: message sent to deallocated instance
Here is my Code to present the Picker.
- (void) setupImagePicker {
IoScreenEditorViewController * ioScreenEditorViewController = (IoScreenEditorViewController *)[UIAppDelegate.ioMainViewController currentViewController];
ioScreenEditorViewController.elementSelectedFromList = [elementsForPage objectAtIndex:0];
// Show an image picker to allow the user to choose a new photo.
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = ioScreenEditorViewController;
imagePicker.allowsEditing = NO;
NSArray * ourMediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil];
[imagePicker setMediaTypes: ourMediaTypes];
[ourMediaTypes release];
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) {
// imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
} else {
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
[imagePicker.view setFrame:CGRectMake(0,0, 340, 500)]; // just for testing
//imagePicker.modalInPopover = YES;
//imagePicker.modalPresentationStyle = UIModalPresentationCurrentContext;
[self.view addSubview:imagePicker.view];
[imagePicker release];
}
I changed the class type that the Picker was being called from to a UIViewController and then altered the presentation code to look like this:
imagePicker.modalInPopover = YES;
imagePicker.modalPresentationStyle = UIModalPresentationCurrentContext;
[self presentViewController:imagePicker animated:NO completion:^{ }];
I still get the Cancel Button, though the Image Picker does seem to be working like it should.
Although I was also as of yet unable to hide the Cancel button of the picker, I would suggest you revise how you are presenting it.
As an effort to get help from the community of iOS developers about this, I've made a sample project, please go and download it. In the project you can see that I am using view controller containment in order to get the picker on screen.
This may perhaps be a better way for you do do this too?

I have a Web Service application and it has alogin view. I want to make my application's login view come when the first time app is loaded(installed) and after that it must allways start with a second view. How can i make it? In this link there are some solutions but i think this isn't what i'm looking for. Since mine is a web servise, mean the content of the second view(which i want to be pushed allways) is fetched from a server(i use NSJSONSerialization class for this work)
I would do the login view as a modal view which is only presented when needed.
Edit:
This is VERY brief: (I assume that you are using ARC.)
In AppDelegate:
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController: mySecondViewController];
if (![self isUserLoggedIn]) {
MyLogInViewController *logInViewController = [[MyLogInViewController alloc] init];
[self presentModalViewController: MyLogInViewController animated: YES];
}
[[self window] setRootViewController: [self navigationController]];
and in logInViewController:
- (void)logInSuccessful {
[self dismissModalViewControllerAnimated: YES];
}
