子类化后的AVPlayerViewController横向

Question

我已经将AVPlayerViewController子类化，以便我可以通过覆盖supportedInterfaceOrientations在iPhone上以横向模式显示它。这很好用。但是当我点击右下角的云选择Subtitle和CC选项时，它将以Portrait模式打开。可能是什么原因？

有没有其他方法可以在横向模式下显示AVPlayerViewController而不进行子类化？

Answer 1

你的意思是只创建一个简单的类吗？因为很简单，只需创建一个新类并添加一个AVLayer而不是创建一个AVPlayerViewController：

NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"mp4"];
    NSURL *videoURL = [NSURL fileURLWithPath:videoPath];

AVPlayerItem * playerItem = [AVPlayerItem playerItemWithURL:videoURL];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(itemDidFinishPlaying:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];

AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = self.view.bounds;
[self.view.layer addSublayer:playerLayer];
[player play];

然后覆盖正确的方法：

- (BOOL)shouldAutorotate {
    return YES;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {

    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {

    return UIInterfaceOrientationLandscapeLeft;
}
