title: UIImagePickerController cameraOverlayView can not be full screen on the iPad
body: <p>this is my code:  </p>
  
  <pre><code>UIImagePickerController *picker = [[UIImagePickerController alloc] init];
  picker.sourceType = UIImagePickerControllerSourceTypeCamera;
  picker.showsCameraControls = NO;
  picker.allowsEditing = NO;
  picker.delegate = self;
  picker.navigationBarHidden = YES;
  picker.toolbarHidden = YES;
  picker.wantsFullScreenLayout = YES;
  
  UIView *overlay = [[UIView alloc] initWithFrame:CGRectZero];
  overlay.backgroundColor = [UIColor greenColor];
  overlay.alpha = 0.3;
  overlay.clipsToBounds = NO;
  
  UIButton *takePictureButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 1024, 1024)];
  [takePictureButton addTarget:self action:@selector(takePictureButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
  takePictureButton.backgroundColor = [UIColor purpleColor];
  [overlay addSubview:takePictureButton];
  
  picker.cameraOverlayView = overlay;
  [takePictureButton release];
  [overlay release];
  
  _currentPicker = picker;
  [self presentModalViewController:picker animated:YES];
  [picker release];
  </code></pre>
  
  <p>And it's look like on iPad 2 with iOS 4.3.2:<br>

  What I want is it can take picture when user tap anywhere on the screen.<br>
  Forgive my poor English.</p>
