Question

When I try to dismiss my UIImagePickerController, it crashes the app. the error is: “Terminating app due to uncaught exception ‘UIApplicationInvalidInterfaceOrientation’, reason: ‘preferredInterfaceOrientationForPresentation must return a supported interface orientation!'”

I have the preferred interface orientation set in my view controller.

-(NSUInteger)supportedInterfaceOrientations
{
 return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
 {
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}

- (BOOL) shouldAutorotate {
return YES;
}

Here is the method I’m calling to bring up the camera, this works fine for adding the camera, but like I said, crashes when I try to remove the camera.

-(IBAction)addCamera:(id)sender
{

self.cameraController = [[UIImagePickerController alloc] init];
self.cameraController.sourceType = UIImagePickerControllerSourceTypeCamera;

self.cameraController.cameraViewTransform = CGAffineTransformScale(self.cameraController.cameraViewTransform,
                                                                   1.13f,
                                                                   1.13f);

self.cameraController.showsCameraControls = NO;
self.cameraController.navigationBarHidden = YES;

self.wantsFullScreenLayout = YES;

ar_overlayView = [[UIView alloc] initWithFrame:CGRectZero];

self.view = ar_overlayView;
[self.cameraController setCameraOverlayView:ar_overlayView];
[self presentViewController:cameraController animated:NO completion:nil];
[ar_overlayView setFrame:self.cameraController.view.bounds];
}

-(IBAction)back:(id)sender
{
[ar_overlayView removeFromSuperview];
[cameraController dismissViewControllerAnimated:NO completion:nil];
}

Alright, found the solution, it was really simple, I just changed my back method to:

    [self dismissModalViewControllerAnimated:YES];

Now my camera goes away and I can see my original view when I press the back button.
I still haven’t figured out what was causing the original problem as I’ve gone through the info.plist and the methods for supported orientations, but this accomplishes what I wanted.

I’m still curious as to what was causing the error though if anyone has any ideas.
