objective-c - 如何手动中断 AVPlayer 来电

Question

我用过这个方法How do I get my AVPlayer to play while app is in background?让 AVPlayer 在后台播放，以便用户可以在浏览 safari 等时收听。现在唯一的问题是 AVPlayer 在有来电时继续播放，并在通话期间保持播放。有没有办法捕获来电和结束通话事件，以便可以手动停止和启动 AVPlayer？

通过coreTelephony 框架，我们必须找到或检测来电。从那里你必须启动你的本地通知来停止你的 AVPlayer。导入后这样做

     CTCallCenter * _callCenter = [[CTCallCenter alloc] init];
    _callCenter.callEventHandler = ^(CTCall* call)
    {

        if ([call.callState isEqualToString:CTCallStateDisconnected])
        {
            NSLog(@"Call has been disconnected");
        }
        else if([call.callState isEqualToString:CTCallStateDialing])
        {
            NSLog(@"Call start");
        }
        else if ([call.callState isEqualToString:CTCallStateConnected])
        {

          NSLog(@"Call has just been connected");
        }
        else if([call.callState isEqualToString:CTCallStateIncoming])
        {
            NSLog(@"Call is incoming");
            // You have to initiate/post your local notification through NSNotification center like this 
        [[NSNotificationCenter defaultCenter] postNotificationName:@"stopAVPlayer" object:nil];
        } else
        {
            NSLog(@"None of the conditions");
        }


    };
