title: UIImagePickerControllerSourceTypePhotoLibrary in iOS 7 is not Working
body: <p>When I upgraded to iOS7, my app is showing an empty view controller when I access the photo Library from the application. It was working with older frameworks.</p>
  
  <pre><code> UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
      imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
      imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
      imagePickerController.delegate = self;
      self.imagePicker = imagePickerController;
      //self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
      [self presentViewController:self.imagePicker animated:YES completion:nil];
  </code></pre>
