title: Presenting UIImagePickerController in camera mode causes crash in iOS 7
body: <p>At the time of presenting UIImagePickerController in camera mode using the code below, Xcode 5 memory view shows that my app consumes about 20 MB. When I present the controller, I receive memory warning in the overrode didReceiveMemoryWarning. But even without a chance to release any resources in there, the app just crashes without leaving any log messages. I am running the code in an iPhone 4S. I see other similar questions but the symptoms are slightly different than mine and I don't see any clear answers that led to resolving my issue. The same code does not cause a problem in iOS 6 or when I present the controller in photo library mode. My specific questions are: </p>
  
  <ol>
  <li><p>Would it be normal to get memory warning with about 20 MB memory usage when presenting UIImagePickerController in camera mode? </p></li>
  <li><p>Should I deal with this problem by reducing the memory consumption level further before I present the UIImagePickerController?</p></li>
  </ol>

      imagePicker.allowsEditing = NO;
  
      imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;  
      [self presentViewController:imagePicker animated:YES completion:nil];
