uiimagepickercontrollercameraoverlayview在iPad上不能全屏

Question

这是我的代码:

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];

在ios4.3.2的iPad 2上是这样的:
对不起，我不能发布图片
我想要的是，当用户点击屏幕上的任何地方时，它都可以拍照。
请原谅我英语不好

我自己解决了这个问题:在 present UIImagePickerController后，重置cameraOverlayView 的大小。
代码如下:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.allowsEditing = NO;
picker.delegate = self;
UIButton *takePictureButton = [[UIButton alloc] initWithFrame:CGRectZero];
[takePictureButton addTarget:self action:@selector(takePictureButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
picker.cameraOverlayView = takePictureButton;
[self presentModalViewController:picker animated:YES];
takePictureButton.frame = CGRectMake(0, 0, 1024, 1024);
[picker release];
[takePictureButton release];

虽然不优雅，但它工作:)
