ios - 子类化后的AVPlayerViewController横向定位

Question

我将AVPlayerViewController子类化，以便可以通过重写supportedInterfaceOrientations在iPhone上以横向模式显示它。这很好。但是，当我单击右下角的云以选择“字幕”和“抄送”选项时，它将以“人像”模式打开。可能是什么原因？

还有其他方法可以在不子类化的情况下以横向模式显示AVPlayerViewController吗？

Answer 1

您是说只创建一个简单的类吗？因为很简单，所以只需创建一个新的Class并添加一个AVLayer即可，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;
}
