How to change AVPlayer Live Streaming URL?

Question

Hi developers and experts, I need your good suggestions and help. I am working an application which has four different radio channels(buttons). I am using AVPlayer for live streaming. I would like to create an AVPlayer object in ViewDidLoad and just change the streaming url by using the four different buttons without having to re-create the AVPlayer object again and again. I googled but not find any solution. So your good suggestions and help would be appreciated. Thanks

- (IBAction)playBtn_clicked:(id)sender {

     NSURL *streamURL = [NSURL URLWithString:urlString];

    // I don't like this line, creating a new object again and again
    _streamPlayer = [[AVPlayer alloc] initWithURL:streamURL]; 

    if (_streamPlayer.rate == 1.0) {
        [_streamPlayer pause];
    } else {
        [_streamPlayer play];
    }
}

My code is so simple . I don't want to create the Player again and again . I want to create it in the viewDidLoad and just change the url with the button clicked. — Nisar Ahmad, Apr 19 '17 at 09:50

AVPlayer has a method to change the "currentItem" to the new one.

On ViewDidLoad()

let player = AVPlayer(playerItem: nil) // You can use an item if you have one

Then, when you want to change the current item... Or set nil to remove it...

player.replaceCurrentItem(with: AVPlayerItem(url: streamingURL))

NOTE: Yeah, it's in Swift 3, I don't have it's ObjC version at hand.

This way, you can create one single instance of AVPlayer, and handle the current AVPlayerItem being played.

ObjC: [player replaceCurrentItemWithPlayerItem:[AVPlayerItem playerItemWithURL:streamingURL]]; — Hans Knöchel, Jan 15 '18 at 08:00

Finally i found the solution by replacing the current item in AVPlayer instead of changing the Streaming URL in the Player.

 - (void)viewDidLoad {
   [super viewDidLoad];
   // Do any additional setup after loading the view.

   _streamPlayer = [[AVPlayer alloc] init];
}


- (IBAction)playBtn_clicked:(id)sender {

  NSURL *streamURL = [NSURL URLWithString:_urlString];
  AVPlayerItem *currentItem = [[AVPlayerItem alloc] initWithURL:streamURL];
  [_streamPlayer replaceCurrentItemWithPlayerItem:currentItem];
}

I'm glad you found the solution, but that's exactly what I've pointed on my comment above (except that mines was in Swift 3). So, if you think my comment helped you, it would be good to mark it as the correct answer. Have a nice coding day! – Esteban Vallejo Jun 05 '17 at 14:16
