ios - 在视频播放期间响应 apple tv 控件

Question

我有一个带有 AVPlayer 的应用程序可以播放视频。我希望能够检测到用户何时按下 Remote 上的按钮。我已经尝试实现以下方法，但是 remoteControlReceivedWithEvent() 不响应任何控制事件。

- (void)remoteControlReceivedWithEvent:(UIEvent *)event {
    //if it is a remote control event handle it correctly
    if (event.type == UIEventTypeRemoteControl) {
        if (event.subtype == UIEventSubtypeRemoteControlPlay) {
            NSLog(@"play");
        } else if (event.subtype == UIEventSubtypeRemoteControlPause) {
            NSLog(@"pause");
        } else if (event.subtype == UIEventSubtypeRemoteControlTogglePlayPause) {
            NSLog(@"toggle");
        }
    }
}

- (BOOL)canBecomeFirstResponder {
    return YES;
}

- (void)viewDidAppear:(BOOL)animated {
    // Setup Apple TV control events
    [super viewDidAppear:animated];
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    [self becomeFirstResponder];
}

- (void)viewWillDisappear:(BOOL)animated {
    // Remove Apple TV control events
    [super viewWillDisappear:animated];
    [[UIApplication sharedApplication] endReceivingRemoteControlEvents];
    [self resignFirstResponder];
}

任何帮助将不胜感激，谢谢!

这似乎是使用 Xcode 7/iOS 9 SDK 构建的项目的问题。使用 Xcode 6 尝试了同样的事情，效果很好。我已经向 Apple bug reporter 提出了这个问题。
