title: iOS 7 UIImagePickerController navigationbar overlap
body: <p>I ran into a problem accessing photo library in iOS7 (iOS6 is OK). It seems navigation bar overlaps the photo album view, I tried to set <code>picker.edgesForExtendedLayout = UIRectEdgeNone;</code> but it doesn't work.</p>
  
  <pre><code>UIImagePickerController *picker = [[UIImagePickerController alloc] init];
  picker.delegate = self;
  picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
  
  if ([[[UIDevice currentDevice] systemVersion] floatValue] &gt;= 7) {
      picker.edgesForExtendedLayout = UIRectEdgeNone;
  }
  
  [self presentViewController:picker animated:YES completion:nil];
  </code></pre>
  
  <p>Look at my screenshot</p>
