如何中斷AVPlayer手動撥入電話

Question

我已經使用此方法How do I get my AVPlayer to play while app is in background?在後臺播放AVPlayer，以便用戶可以在瀏覽Safari瀏覽器時進行收聽等。現在只有問題是AVPlayer在有來電時繼續播放並在通話過程中保持播放。有沒有辦法捕捉來電和結束通話事件，以便AVPlayer可以停止並手動啓動？

通過coreTelephony框架，我們必須找到或檢測來電。從那裏你必須發起你的本地通知來停止你的AVPlayer。 導入後做這樣的

 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"); 
     } 


    };
