ios-UIImagePickerControllerSourceTypeCamera中的UIImagePickerController在iOS7中崩潰EXC_BAD_ACCESS

Question

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];

此代碼使ios7設備上的EXC_BAD_ACCESS崩潰。 在iOS6上-一切正常，並且UIImagePickerControllerSourceSourcePhotoPhotoLibrary正常工作。

使用相機

if ([UIImagePickerController isSourceTypeAvailable:
     UIImagePickerControllerSourceTypeCamera]) {
    UIImagePickerController* imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.delegate = self;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.mediaTypes = [NSArray arrayWithObjects:
                                        (NSString *) kUTTypeImage,
                                        (NSString *) kUTTypeMovie, nil];
    [self presentViewController:imagePickerController animated:YES completion:nil];    }
