【问题描述】：

我正在使用 AVPlayerViewController 来显示带有 AVPlayer 的视频。

当我锁定手机屏幕时，视频会继续在后台播放。

如何防止这种情况发生？

【参考方案1】：

试试这个禁用音频和 Airplay 的背景模式

- (void)applicationDidEnterBackground:(UIApplication *)application 
     // pause the video here
 

- (void)applicationWillEnterForeground:(UIApplication *)application      
    // resume video when screen unlock

    if (self.backgroundedToLockScreen) 
        ... // App was backgrounded to lock screen

    self.backgroundedToLockScreen = NO;
