Ipad UIImagePickerController不'；t显示旋转按钮

这是一款iPhone应用程序，在iOS7的iPad上运行。在iPhone中，它工作正常。 然而，在iPad中，旋转按钮不显示，视图就像在顶部被切断一样。 我没有对图像选择器做任何奇怪的事情。下面是我如何展示它的：

- (void)showImagePickerWithSourceType:(UIImagePickerControllerSourceType)sourceType
{
     UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
     imagePicker.mediaTypes = @[(NSString*)kUTTypeImage];
     imagePicker.sourceType = sourceType;
     imagePicker.delegate = self;
     imagePicker.allowsEditing = YES;

     //Select front facing camera if available
     if (sourceType == UIImagePickerControllerSourceTypeCamera && [UIImagePickerController   isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront])
     {
         imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
     }

     [self presentViewController:imagePicker animated:YES completion:nil];
}

你能发布iPad应用程序的屏幕截图吗？很抱歉耽搁了。我对问题进行了编辑以添加屏幕截图。@mdonati您找到解决方案了吗？
