Xcode AVCam不'；不适用于景观模式

我使用的是苹果公司提供的AVCam示例，但出于我应用程序的目的，对其进行了一些修改。然而，除了修复一些其他问题外，没有任何原始内容被真正触及。然而，当它在横向模式下工作时，我遇到了一个主要障碍

我从stackoverflow的另一个问题中获得了正确的类中的以下代码：

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {

[CATransaction begin];
if (toInterfaceOrientation==UIInterfaceOrientationLandscapeLeft){
    captureVideoPreviewLayer.orientation = UIInterfaceOrientationLandscapeLeft;
} else {
    captureVideoPreviewLayer.orientation = UIInterfaceOrientationLandscapeLeft;
}

[CATransaction commit];
[super willAnimateRotationToInterfaceOrientation:toInterfaceOrientation duration:duration];
}

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];

return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
} 

但是，它不起作用。此代码的目的是在移动手机时允许横向移动。每次移动方向时，控制台中都会弹出一条警告：

WARNING: -[<AVCaptureVideoPreviewLayer: 0x1ed97620> setOrientation:] is deprecated.  Please use AVCaptureConnection's -setVideoOrientation:

警告：-[setOrientation:]已弃用。请使用AVCaptureConnection的-setVideoOrientation：

不确定如何修复此弃用错误，或者是否是弃用导致它无法切换到横向。救命啊

我可以为您提供一个解决方案，为我解决这个问题，即使我确信一定有更好的解决方案：

-(void)willAnimateRotationToInterfaceOrientation (UIInterfaceOrientation)toInterfaceOrientation
                                    duration:(NSTimeInterval)duration {
if (![[[self captureManager] recorder] isRecording]) {
[CATransaction begin];
if (toInterfaceOrientation==UIInterfaceOrientationLandscapeLeft){
    captureVideoPreviewLayer.orientation = UIInterfaceOrientationLandscapeLeft;
    captureVideoPreviewLayer.frame = CGRectMake(0, 0, 480, 320);

} else if (toInterfaceOrientation==UIInterfaceOrientationPortrait){
    captureVideoPreviewLayer.orientation = UIInterfaceOrientationPortrait;
    captureVideoPreviewLayer.frame = CGRectMake(0, 0, 320, 480);

} else if (toInterfaceOrientation==UIInterfaceOrientationLandscapeRight){
    captureVideoPreviewLayer.orientation = UIInterfaceOrientationLandscapeRight;
    captureVideoPreviewLayer.frame = CGRectMake(0, 0, 480, 320);

}

[CATransaction commit];
[super willAnimateRotationToInterfaceOrientation:toInterfaceOrientation duration:duration];
}

---

}

要在录制过程中禁用自动旋转：-（BOOL）应自动旋转{if（！[[[self captureManager]recorder]isRecording]）{返回是；}否则返回否；}
