iPad iOS7 - UIImagePickerController in UIPopoverController has wrong preview image

Question

I am using an UIImagePickerController within an UIPopoverController which is working perfectly with iOS6. With iOS 7 the \"preview\" image which is shown to capture the imag

Answer 1

I've found another solution which handles the case where a device is rotated while the UIIMagePickerView is presenting based on the answer Journeyman provided. It also handles the case where the view is rotated from UIOrientationLandscapeRight/UIOrientationLandscapeLeft back to UIOrientationPortrait.

I created a subclass of UIImagePickerController:

#import 

@interface PMImagePickerController : UIImagePickerController

@end

Then registered it to receive notifications if the device orientation changes:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(fixCameraOrientation:) name:UIDeviceOrientationDidChangeNotification object:nil];

The selector fixCameraOrientation contains Journeyman's code with one extra case, wrapped in a check to make sure the sourceType is the camera:

- (void)fixCameraOrientation:(NSNotification*)notification
{
    if (self.sourceType == UIImagePickerControllerSourceTypeCamera) {
        CGFloat scaleFactor=1.3f;

        switch ([UIApplication sharedApplication].statusBarOrientation) {
            case UIInterfaceOrientationLandscapeLeft:
                self.cameraViewTransform = CGAffineTransformScale(CGAffineTransformMakeRotation(M_PI * 90 / 180.0), scaleFactor, scaleFactor);
                break;


            case UIInterfaceOrientationLandscapeRight:
                self.cameraViewTransform = CGAffineTransformScale(CGAffineTransformMakeRotation(M_PI * -90 / 180.0), scaleFactor, scaleFactor);
                break;

            case UIInterfaceOrientationPortraitUpsideDown:
                self.cameraViewTransform = CGAffineTransformMakeRotation(M_PI * 180 / 180.0);
                break;

            case UIInterfaceOrientationPortrait:
                self.cameraViewTransform = CGAffineTransformIdentity;
                break;

            default:
                break;
        }
    }

}

The important case here is the case where the device orientation goes to portrait. The overlay's view needs to be reset in this case. It's also important for the fixCameraOrientation selector to be called after the image picker view loads, in case the device is rotated:

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self fixCameraOrientation:nil];
}
