UIImagePickerController相机实时预览错误的横向iPad应用程序方向

Question

我有一个实现UIImagePickerController源类型相机的iPad应用程序。当为设备启用旋转时，如果我在保持纵向模式的情况下从图像选择器中选择相机（应用程序仅支持横向模式），则相机视图将显示90度旋转。如果我们锁定旋转，相机工作正常。用于呈现相机视图的代码是 -

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.delegate = self;

self.imagePickerController = imagePickerController;
    [self presentViewController:self.imagePickerController
                       animated:YES
                     completion:nil
     ];

有人有任何建议吗？
