Solution

  • You have to present the UIImagePickerController as a modal view controller. So don't push your controller, but present it as modal:

    [self.navigationController presentModalViewController:imagePickerController animated:YES];

    You can pop the image picker using -[UINavigationController dismissModalViewControllerAnimated:] to go back to the last view controller on the stack.
