AVPlayer在后台播放视频

我正在使用AVPlayer在我的应用中播放视频，现在我想让该视频在后台模式下播放.

I am using AVPlayer to play a video in my app,now i want to let the video play in background mode.

这就是我放入的- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions:

[[AVAudioSession sharedInstance] setDelegate: self]; [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];

，我也添加到plist中: 所需的背景模式->应用播放音频

and i also add to the plist: Required background modes -> App plays audio

我也添加了它:

-(void)viewDidAppear:(BOOL)animated{ [super viewDidAppear:animated]; [[UIApplication sharedApplication] beginReceivingRemoteControlEvents]; [self becomeFirstResponder]; } - (BOOL)canBecomeFirstResponder { return YES; } - (void)remoteControlReceivedWithEvent:(UIEvent *)event { switch (event.subtype) { case UIEventSubtypeRemoteControlTogglePlayPause: NSLog(@"4"); break; case UIEventSubtypeRemoteControlPlay: break; case UIEventSubtypeRemoteControlPause: NSLog(@"3"); break; case UIEventSubtypeRemoteControlNextTrack: NSLog(@"2"); break; case UIEventSubtypeRemoteControlPreviousTrack: NSLog(@"1"); break; default: break; } }

当我将应用程序移至后台并按下按钮时，nslog将打印到控制台

And when i move the app to the background and press the buttons the nslog print to the console

我需要添加其他内容吗?

Did i need to add something else?

推荐答案

只需添加[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];和其他一些调整即可.都是此处.

Just add [[UIApplication sharedApplication] beginReceivingRemoteControlEvents]; and some other tweaks. It's all here.
