There may be a better way to do this, and please direct me if there is.
I'm creating an UIImagePickerController with an overlayView in viewDidAppear for 'choose from library', 'take photo', 'flash' 'camera source', etc.
// Set up the camera
imagePicker = [[UIImagePickerController alloc]
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
imagePicker.cameraOverlayView = [self cameraOverlayView];
cameraOverlayView.backgroundColor = [UIColor clearColor];
imagePicker.showsCameraControls = NO;
imagePicker.toolbarHidden = YES;
imagePicker.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:imagePicker animated:YES];
I then have an IBAction that calls my 'choose from library function', loading another UIImagePickerController to choose a photo from the device.
- (IBAction)library:(id)sender
{
UIImagePickerController *libraryPicker = [[[UIImagePickerController alloc] init] autorelease];
libraryPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
libraryPicker.delegate = self;
[self.imagePicker presentModalViewController:libraryPicker animated:YES];
}
I'm getting a white bar across the top about the size of a status bar when the 'choose from library' modal is presented. I know it has something to do with overlaying a modal on top of a modal, but I don't know how to solve it. (IE, my view layout for 'take photo' navigates fine, although doesn't display the additional 'choose from library' modal).
Any ideas? Any help or direction would be greatly appreciated!
Try
[self presentModalViewController:libraryPicker animated:YES];
Instead of
[self.imagePicker presentModalViewController:libraryPicker animated:YES];

How can I add custom button in UIImagePickerController popover when I am selecting image from gallery?
Got it. These are by default buttons provided by Apple for UIImagePickerViewController. So there is one property you have to use and property is allowsEditing. You have to set it as YES
So that after selecting photo from gallery or camera, those 2 buttons will be shown.
Code should be like:
-(void)openGallery {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
-(void)openCamera {
BOOL isCameraPresent = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
if(isCameraPresent) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
// Add overlay view with custom button on it. Set frames to button as per your choice.
UIView *viewOverlay = [[UIView alloc]initWithFrame:self.view.bounds];
Create and initialise your `UIButton` here
[viewOverlay addSubview:YOUR_BUTTON_OBJECT];
picker.cameraOverlayView = viewOverlay;
[self presentViewController:picker animated:YES completion:NULL];
}
else {
NSLog(#"Camera not present");
}
}
YOU CAN ADD OVERLAY ONLY IF sourceType is UIImagePickerControllerSourceTypeCamera
Make sure that you have confirmed UIImagePickerControllerDelegate protocol in your view controller.
Call those actions on tap of button or action sheet actions as per your choice.
NOTE: UI of popover of UIImagePickerController is dependent on iOS version of device.
I am new to xcode . In my view controller have images gallery option . User can tab the image to view and add the images. When the user click the add new image option , its show popup there two option like image and camera.
user can add the images from gallery as well as capture the new images from camera. In the case , my camera view working fine. Then i click the gallery view the gallery photos are shown perfectly. But when i rotate the gallery photos view to the landscape ,its automatically goes to the camera in sideway. This is my problem.. I want to when phone rotate the photos gallery in landscape its not going to camera view sideway. Please any one help me.
my code is below
- (void)viewWillAppear:(BOOL)animated {//
[super viewWillAppear:animated];
if (!self.disableGalleryUpdate) {
//This will replace share button in FSImageViewController share button in navigation bar
HPLBarButton *barButton = [HPLBarButton barButtonWithImage:AddNewContractor forTarget:self withSelector:#selector(addObject:)];
self.navigationItem.leftBarButtonItem = barButton;
} else {
self.navigationItem.leftBarButtonItem = nil;
}
APP_DELEGATE.screenHasMultipleOrientation = YES;
[self.navigationController setNavigationBarHidden:NO];
}
- (void)addImageClicked:(id)sender {
[[HPLImageSourceSelectionDeviceManager device] showImageSourceSelectionInView:self.view
withGalleryButtonAction:^{[self camera];}
cameraButtonActionBlock:^{[self gallery];}
];}
-(void)camera
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:nil];
}
-(void)gallery
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:nil];
}
When i choose image gallery view in potrait

In my iPad app I create and resize a modal view like this:
ModalViewController *modalController = [[WishlistInfoViewController alloc] initWithNibName:#"WishlistInfoViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:modalController];
navController.modalPresentationStyle = UIModalPresentationPageSheet;
self presentViewController:navController animated:YES completion:nil];
navController.view.superview.bounds = CGRectMake(0, 0, 700, 700);
navController.view.superview.center = CGPointMake(self.view.center.x, self.view.center.y + 35);
Inside that modal view I launch the camera like this:
UIImagePickerController *mypicker = [[UIImagePickerController alloc] init];
mypicker.delegate = self;
mypicker.allowsEditing = NO;
mypicker.sourceType = UIImagePickerControllerSourceTypeCamera;
mypicker.showsCameraControls = YES;
mypicker.wantsFullScreenLayout = YES;
[self.navigationController presentModalViewController:mypicker animated:YES];
I dismiss the camera like this:
[self dismissModalViewControllerAnimated:TRUE];
The problem is that when I dismiss the camera the modal view is resized to fill the whole screen. What can I do to prevent the modal view from resizing?
Ok, so I fixed my issue but just resetting the size of the view right after calling [self dismissModalViewControllerAnimated:YES];. I don't know why I didn't try this until now.
I am trying to change the size of a UIImagePicker which I am presenting via a UIPopOver. The code is shown below. The issue is that the PopOver size doesn't display properly - it briefly flashes up in the correct size, then animates down to the usual default size.
Can anybody advise me on how I can change the size of the popover ?
- (void)showImagePickerForPhotoLibrary {
NSLog(#"Picker");
imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.contentSizeForViewInPopover = CGSizeMake(768, 1000);
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
Class cls = NSClassFromString(#"UIPopoverController");
if (cls != nil) {
popoverController = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
//popoverController.popoverContentSize = CGSizeMake(768, 1000);
[popoverController presentPopoverFromRect:selectedRect inView:self.view permittedArrowDirections:4 animated:YES];
}
}
else {
[app.mainViewController presentModalViewController:imagePickerController animated:YES];
}
}
I'm not sure this is the most elegant solution, however it seems to work fine for me:
You can embed the UIImagePickerController's view into a "container" UIViewController's view.
- (void)showImagePickerForPhotoLibrary {
NSLog(#"Picker");
imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
UIViewController *containerController = [[UIViewController alloc] init];
containerController.contentSizeForViewInPopover = CGSizeMake(768, 1000);
[containerController.view addSubview:imagePickerController.view];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
Class cls = NSClassFromString(#"UIPopoverController");
if (cls != nil) {
popoverController = [[UIPopoverController alloc] initWithContentViewController:containerController];
[popoverController presentPopoverFromRect:selectedRect inView:self.view permittedArrowDirections:4 animated:YES];
[imagePickerController.view setFrame:containerController.view.frame];
}
}
else {
[app.mainViewController presentModalViewController:containerController animated:YES];
}
}
Hope this helps
EDIT: for some strange reason, the frame does indeed change when in landscape right.
To come over this, you need to set the image picker's view's frame after you present the popover.
I have edited the code above to show this.
Also, in your controller, add this:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
[imagePickerController.view setFrame:imagePickerController.view.superview.frame];
}
When I tried Mutix's solution the popover showed just the navigation bar with an empty white view.
My way around it was to add imagePickerController as a child of containerController and not just adding the picker's view.
Mainly it means to replace this line:
[containerController.view addSubview:imagePickerController.view];
with these lines:
[containerController addChildViewController:imagePickerController];
[containerController.view addSubview:imagePickerController.view];
[imagePickerController didMoveToParentViewController:containerController];
In addition, when using this approach, I didn't need any special handling for landscape mode.
I am showing a UIImagePicker (itself in a UIView) via a UIPopOver. This works fine, however when the iPad is rotated onto its right side I get a strange black bar along the left hand side of the popover as per the image below. The cancel button is also partially off the right hand of the screen. This doesn't happen in any other orientation which is odd.
The code is also listed below. Can anyone suggest why I am getting this black bar ?
imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
CGFloat width = CGRectGetWidth(self.view.bounds);
CGFloat height = CGRectGetHeight(self.view.bounds);
UIViewController *containerController = [[UIViewController alloc] init];
containerController.contentSizeForViewInPopover = CGSizeMake(width, height);
[imagePickerController.view setFrame:containerController.view.frame];
[containerController.view addSubview:imagePickerController.view];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
Class cls = NSClassFromString(#"UIPopoverController");
if (cls != nil) {
popoverController = [[UIPopoverController alloc] initWithContentViewController:containerController];
[popoverController presentPopoverFromRect:selectedRect inView:self.view permittedArrowDirections:4 animated:YES];
[containerController release];
}
For some strange reason, the view's frame does change in landscape right.
To come over this, set the frame after you present the popover (view code below).
That should do the trick.
imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
CGFloat width = CGRectGetWidth(self.view.bounds);
CGFloat height = CGRectGetHeight(self.view.bounds);
UIViewController *containerController = [[UIViewController alloc] init];
containerController.contentSizeForViewInPopover = CGSizeMake(width, height);
[containerController.view addSubview:imagePickerController.view];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
Class cls = NSClassFromString(#"UIPopoverController");
if (cls != nil) {
popoverController = [[UIPopoverController alloc] initWithContentViewController:containerController];
[popoverController presentPopoverFromRect:selectedRect inView:self.view permittedArrowDirections:4 animated:YES];
[imagePickerController.view setFrame:containerController.view.frame];
[containerController release];
}
Also, in your controller, add this to reset the frames when the rotation occurs:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
[imagePickerController.view setFrame:imagePickerController.view.superview.frame];
}
The above approach works with iOS 5 and above but on iOS 4 and prior it's not possible to add the UIImagePickerController as a subview and then show it. It always has to be presented as a ModalViewController.
Try this. Reposting one solution I found using [currentDevice endGeneratingDeviceOrientationNotifications]
UIImagePickerController *picker = [[[UIImagePickerController alloc] init] autorelease];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
// Display the camera.
[self presentModalViewController:picker animated:YES];
// Given by default your orientation is in landscape right already
while ([currentDevice isGeneratingDeviceOrientationNotifications])
[currentDevice endGeneratingDeviceOrientationNotifications];
