We need to set the AVPlayer to nil so that the app continue playing the audio in the background .

the problem is how to get the AVPlayer instance from AppDelegate I tried this method but nothing work and the app crash when I Enter the Background

I found the answer

we need to controll applicationDidEnterBackground and applicationDidEnterBackground in the same Player UIViewController class by adding this 2

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(disconnectAVPlayer) name:UIApplicationDidEnterBackgroundNotification  object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reconnectAVPlayer) name:UIApplicationWillEnterForegroundNotification  object:nil];

then we can set VideoPlayer to nil like this

- (void)disconnectAVPlayer{
    self.playerLayer.player = nil;
}

- (void)reconnectAVPlayer{
    self.playerLayer.player = self.VideoPlayer;    
}

NOTE : We need to set AVPlayerLayer to nil not the actual AVPlayer
