How to play a video in background using YTPlayer in iOS app?

Question

I am getting the following error message...

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[YTPlayerView playerView]: unrecognized selector sent to instance 0x7fd77bd41f80'

and here is my code..

- (void)applicationDidEnterBackground:(NSNotification *)notification
{   
    [_playerView performSelector:@selector(playerView) withObject:nil afterDelay:0.1];

}

- (IBAction)didTapPlayPause:(id)sender {
    self.btnPlayPause.selected = !self.btnPlayPause.selected;
    if (self.btnPlayPause.selected)
    {
        self.title=self.strngvideotitle;
        self.playerView=[[YTPlayerView alloc]initWithFrame:CGRectMake(0,0,375,290)];
        [self.playerView loadWithVideoId:self.strngvideoId];
        [self.view addSubview:_playerView];

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

   }

@Anbu.Karthik....I changed it but still showing the same error message — Roby, May 22 '17 at 06:03
change this `[_playerView performSelector:@selector(playerView)` into `[self performSelector:@selector(playerView)` and try once — Anbu.Karthik, May 22 '17 at 06:05
@Roby Anbu asked for the code of `playerView` method, which may be like `-(void)playerView{};` — Piyush, May 22 '17 at 06:07
@Roby - can you show your `playerView` this method where you created — Anbu.Karthik, May 22 '17 at 06:13

Your code fails at this statement

[_playerView performSelector:@selector(playerView) withObject:nil afterDelay:0.1];

The statement expects that your _playerView object will call the method playerView after a delay of 0.1 seconds. But the class YTPlayerView does not have a method called playerView. You might want to check the actual method name and replace it in the selector name.

ya may be correct, allocate your `self.playerView=[[YTPlayerView alloc]` in didfinish launch o – Anbu.Karthik May 22 '17 at 06:22
That is not the point. The problem is that there is no method called `playerView`. The method would be called something else like `playVideo` maybe (https://github.com/youtube/youtube-ios-player-helper/blob/master/Classes/YTPlayerView.h#L247) – lostInTransit May 22 '17 at 06:27
