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iPad 2上看起来像iOS 4.3.2： sorry, I can't post image
我想要的是当用户点击屏幕上的任何地方时它可以拍照原谅我可怜的英语。

我自己解决了这个问题：只需重置目前UIImagePickerController后的cameraOverlayView 的大小。
像这样的代码：

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];

虽然它不优雅，但它有效：）
