My code to place an overlay in the imagepicker works in iOS6, but not in ios7. In iOS6 the camera display fine; it appears that the overlay is slotted between the picker and the controls nicely. In iOS7, it seems that the overlay is placed on the very top layer, hiding the controls. I can still click on the take photo button though.
Is there anyway to put the camera controls back on top? Or is this a bug?
imagePicker =[[UIImagePickerController alloc] init];
overlayView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageString]];
imagePicker.cameraOverlayView = overlayView;
imagePicker.delegate=self;
imagePicker.title=#"Test";
imagePicker.showsCameraControls = YES;
[self presentModalViewController:imagePicker animated:YES ];
[imagePicker release];

I am developing app for iPad, in Landscape mode during taking a snapshot from camera a black preview appears.While , UIImagePickerController works properly for Portrait mode.Thanks in advance.
this is my piece of code -
-(UIImagePickerController *)imagePicker{
if(!imagePicker){
imagePicker = [[UIImagePickerController alloc]init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
}
return imagePicker;
}
[self presentViewController:self.imagePicker animated:YES completion:^{ }];
PS: Anybody knows about, "Contacts" default app of iOS device having this feature rotation of camera controls with respect to device orientation.Here, Camera preview looks fine for all orientation.Anybody knows its implementation.
if you are using Autolayout then you first Check for the co-ordinates and size of corresponding preview(UIimageview).
I have a iPad application in Landscape orientation (iOS7), but when I present a UImagePickerViewController (Camera), this can be in portrait mode and need to avoid it.
Is there any way to lock this portrait orientation?
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
imagePicker.allowsEditing = NO;
[self presentViewController:imagePicker animated:YES completion:NULL];
Thanks In advance.
Edit: I have followed the next iOS7 iPad Landscape only app, using UIImagePickerController and now the bars of the camera and preview picture taken appears in landscape mode, but if I take a photo with iPad in portrait orientation (app keeps on landscape orientation) the preview image rotates 90 degrees and 2 black sections appear on each side.
So, what I need is avoid this rotation in preview picture in the UIImagePickerViewController.
Does anyone have any idea?
I have a transparent view with a rectangle drawn onto it using CoreGraphics.
When the camera launches the custom overlay view is above the shutter animation.
What you see is the standard camera shutter with the custom rectangle above it.
How do I get it to go in the right place, underneath the shutter animation? I've looked at other sample code but it's for OS 3.1 and doesn't seem to do anything differently.
Here's my code:
-(IBAction)cameraButton{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerCameraDeviceRear]){
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
//Add the OverlayView with the custom Rectangle
CGRect overlayFrame = CGRectMake(0.0f, 0.0f, 320.0f, 480.0f);
OverlayView *overlayView = [[OverlayView alloc]initWithFrame:overlayFrame];
picker.cameraOverlayView = overlayView;
[overlayView release];
[self presentModalViewController:picker animated:YES];
[picker release];
}
}
On the iPad this problem doesn't exist, and the overlay view is behind the shutter animation by default. But on the iPhone, the overlay appears at front.
I've found a solution that worked for me.
You have to set your overlay view as a subview in this method:
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
if (!viewController)
return;
UIView* controllerViewHolder = viewController.view;
UIView* controllerCameraView = [[controllerViewHolder subviews] objectAtIndex:0];
UIView* controllerPreview = [[controllerCameraView subviews] objectAtIndex:0];
[controllerCameraView insertSubview:self.overlayView aboveSubview:controllerPreview];
}
Hope it helps

You may not do anything else other than what you're already doing; if iOS decides to put your overlay view over the shutter, you'll just have to live with it (unless you want to risk getting rejected from the app store).
As an imperfect workaround, you could start your overlay with alpha=0 and then set alpha to 1 a second or two later. But there is no set time period that the shutter appears for before 'opening' (I think it depends on how long it takes to initialize the camera hardware), so sometimes your interface might not appear until late and sometimes might appear too early.
As of 4.3.3, the shutter animation is broken because elements are displayed on top, and then snap underneath when the animation starts. I've filed this as a Radar: http://openradar.appspot.com/radar?id=1204401
I answered a similar question here. What worked for me (in iOS 6) was setting the cameraOverlayView in navigationController:willShowViewController:animated.
- (void) navigationController:(UINavigationController*) navigationController willShowViewController:(UIViewController*) viewController animated:(BOOL) animated {
self.imagePickerController.cameraOverlayView = ...; // your camera overlay view
}
Is there any model view like this on the iPad?
Yes, there is:
UIModalPresentationFormSheet
The width and height of the presented view are smaller than those of the screen and the view is centered on the screen. If the device is in a landscape orientation and the keyboard is visible, the position of the view is adjusted upward so that the view remains visible. All uncovered areas are dimmed to prevent the user from interacting with them.
For example:
UIViewController *viewController = [[UIViewController alloc] init];
viewController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:viewController animated:YES];
viewController.view.superview.frame = CGRectMake(0, 0, 540, 500); // this is important to do this after presentModalView
viewController.view.superview.center = self.view.superview.center;
I'm using MPMoviePlayerViewController - with the player controls set to: MPMovieControlStyleFullscreen
I'm having a problem with some of buttons that are in MPMovieControlStyleFullscreen: forward, reverse, and fullscreen (the one with the arrows pointing at eachother).
I would like to either remove the forward, reverse, and fullscreen buttons or control what they do when the user taps them.
Thank you!
There isn't a way to customize the MPMovieControlStyle values provided by Apple. What you need to do is is turn off the Apple controls (MPMovieControlStyleNone) and then create your own custom controls. Apple is fine with you putting your own UIViews in to the hierarchy here, so you can get started with something like this:
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: YOUR_URL];
moviePlayer.controlStyle = MPMovieControlStyleNone;
UIView *movieView = moviePlayer.view;
[movieView addSubview: _movieControlsView];
[movieView bringSubviewToFront: _movieControlsView];
Where _movieControlsView was set up earlier in code or in IB.
Aesthetically, you can do what you want, but I would recommend sticking with something that looks like Apple's choices so as not to confuse the user. For the project I just finished, I created a transparent button the exact size of the movie player. Clicking the button fades in a control bar on the bottom with my custom controls. If one of the controls isn't clicked, the control bar fades back out again after a few seconds.
First off, MPMoviePlayerController is a little different than MPMoviePlayer*View*Controller, so some of these answers lead to problems when converting applications that were built in an iOS 4.3+ environment.
I've built some apps using MPMoviePlayerController that worked fine when built in iOS 3.2. When I rebuilt it with XCode 3.2.6, (iOS 4.3), the videos don't even play on the iPhone. I since fixed that by adding the MPMoviePlayerController instance to a subView, then presenting a modal (Player is a UIViewController) with the movplayer in fullScreenMode:
//from didSelectRowAtIndexPath
Vid *selected = [items objectAtIndex:position];
player = [[Player alloc] init];
movplayer = [[MPMoviePlayerController alloc] initWithContentURL:selected.vidURL];
movplayer.view.frame = player.view.bounds;
movplayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight |
UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[player.view addSubview:movplayer.view];
[self presentModalViewController:player animated:YES];
[movplayer setFullscreen:YES animated:NO];
[movplayer play];
[player release];
//movplayer is released inside - (void)exitedFullscreen:(NSNotification*)notification
This was done on account of the UINavigationBar being half cut off when rotating.
When I got to the iPad version of the app the modal option wouldn't work aesthetically. It was also having the UISplitViewController navBar and toolbars half cut off when rotating in full screen mode. So I tried implementing MPMoviePlayerViewController instead of MPMoviePlayerController. With this conversion, XCode gave me errors when trying to set:
movplayer.controlStyle = MPMovieControlStyleEmbedded;
The proper way to do this with a MPMoviePlayerViewController is:
movplayer.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
When the player is added as a subView, the pinch gestures will toggle the player between fullScreen and the size of your parentView (player.view.bounds) smoothly, as well as preserve the toolbars and navBars native to the parent.
//iPad version with a view (viewForMovie) inside the DetailViewController
movplayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[current vidURL]];
movplayer.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
movplayer.view.backgroundColor = [UIColor clearColor];
movplayer.view.frame = viewForMovie.bounds;
[viewForMovie addSubview:movplayer.view];
So these two examples show some workarounds for those who want to convert their iPhone or iPad apps to a newer iOS version.
Try setting MPMovieControlStyle of your MPMoviePlayerController object to MPMovieControlStyleNone
