横竖屏切换崩溃

[wlinshicong]

利用AVCaptureConnection，设置了横屏状态下的videoConnection.videoOrientation = AVCaptureVideoOrientationLandscapeRight，横竖屏切换N次之后会崩溃

在AVCaptureViewController的viewDidLoad里加入[[NSNotificationCenter defaultCenter] addObserverForName:UIApplicationDidChangeStatusBarOrientationNotification object:nil queue:nil usingBlock:^(NSNotification * _Nonnull note) {

    //UIDeviceOrientationFaceUp
    switch ([UIApplication sharedApplication].statusBarOrientation) {
        case UIInterfaceOrientationLandscapeLeft:

// stuckview.affineTransform = CGAffineTransformMakeRotation(M_PI+ M_PI_2); // 270 degress
weakSelf.videoConnection.videoOrientation = AVCaptureVideoOrientationLandscapeLeft;
NSLog(@"横屏 左侧");
break;
case UIInterfaceOrientationPortrait:
// stuckview.affineTransform = CGAffineTransformMakeRotation(M_PI_2); // 90 degrees
weakSelf.videoConnection.videoOrientation = AVCaptureVideoOrientationPortrait;
NSLog(@"竖屏向下x");

            break;
        case UIInterfaceOrientationLandscapeRight:

// stuckview.affineTransform = CGAffineTransformMakeRotation(M_PI); // 180 degrees
weakSelf.videoConnection.videoOrientation = AVCaptureVideoOrientationLandscapeRight;

            NSLog(@"竖屏向下");
            break;
        default:
            NSLog(@"qita");
            break;
    }
}];

声明
@Property (strong, nonatomic) AVCaptureConnection *videoConnection;//视频录制连接
懒加载了videoConnection
//视频连接

• (AVCaptureConnection *)videoConnection {
  _videoConnection = [self.videoDataOutput connectionWithMediaType:AVMediaTypeVideo];
  return _videoConnection;
  }

复现流程：横屏启动程序-》点击开始——》转屏到竖屏——》崩溃
如果是让ipad保持竖屏，然后启动程序，好像怎么转都不会崩溃
