Lock UIImagePickerController in Portrait mode in ios app

In my iOS app, when I open the camera, I put the image on the camera. It looks good in portrait mode. But when it is changed in landscape mode, it looks a little strange. So I want to lock UIImagePickerControllerin portrait mode.

Below is my code for ui image select controller

UIImagePickerController *imgPkr = [[UIImagePickerController alloc] init];
imgPkr.delegate = self;
imgPkr.sourceType = UIImagePickerControllerSourceTypeCamera;

How can it be blocked in portrait mode ....

This is not the best solution, but it works:

AppDelegate *appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];
[appDelegate.window addSubview:cameraOverlay];
imgPicker.cameraOverlayView = appDelegate.window.superview;

The camera in the background is still rotating, but your overlay view is not working. Hope this works for you.

Or you can subclass UIImagePickerController:

UIImagePickerController .

- (BOOL)shouldAutorotate{
return NO;
}

, , UIImagePickerController .

}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}
@end
