ios - AVPlayerViewController 上没有 "Done"按钮

Question

我正在使用 AVPLayerViewController 来流式传输内容。回放工作正常，但我没有看到关闭 View 的“完成”按钮。

这是我如何设置和显示 View Controller

NSURL* url = [content localSessionUrl];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.player = [AVPlayer playerWithURL:url];
[self.navigationController pushViewController:playerViewController animated:YES];
[self.navigationController setNavigationBarHidden:YES];

是不是因为我在导航 Controller 上推送它？

与其推送或添加 subview ，不如尝试呈现 View 。完成按钮将自动显示。下面是代码片段。

-(void)playVideoWithUrl:(NSURL *)url{
    AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc]init];
    playerViewController.player = [[AVPlayer alloc]initWithURL:url];
    [self presentViewController:playerViewController animated:YES completion:nil];
    playerViewController.view.frame = self.view.frame;
    [playerViewController.player play];
}
