iphone - UIImagePicker allowsEditing卡在中心

Question

我有一个 UIImagePicker，它非常适合一种 UIImagePickerControllerSourceTypePhotoLibrary，但是当我使用 UIImagePickerControllerSourceTypeCamera 时，编辑框无法从图像的中心移动。因此，如果图片的高度大于宽度，则用户无法将编辑框移动到图片的顶部正方形。

有人知道为什么会这样吗？只有当源来自相机而不是库时才会发生这种情况。

编辑:一些代码!!!

if (actionSheet.tag == 2) {
    if (buttonIndex == 0) { // Camera
        // Check for camera
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES) {
            // Create image picker controller
            UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

            // Set source to the camera
            imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;
            imagePicker.allowsEditing = YES;

            // Delegate is self
            imagePicker.delegate = self;

            // Show image picker
            [self presentViewController:imagePicker 
                               animated:YES 
                             completion:^(void) {
                             }];
        }
    }
    else if (buttonIndex == 1) { // Photo Library
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary] == YES) {
            // Create image picker controller
            UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

            // Set source to the camera
            imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            imagePicker.allowsEditing = YES;

            // Delegate is self
            imagePicker.delegate = self;

            // Show image picker
            [self presentViewController:imagePicker 
                               animated:YES 


                          completion:^(void) {
                                 }];
            }
}

如您所见，我显示它们完全相同，但相机编辑与照片库编辑的行为不同。

看起来这种行为只是 iOS 6 中的一个错误...基本上您不能移动编辑框，除非您放大一点，否则它总是弹回到中间。希望他们能尽快解决这个问题。
