Adding activity indicator while AVplayer gets ready to play music

audio-streaming, avplayer, ios

Solution

This will add the activity view to the center of the view. Add this code in the "IBAction" where u handle the play button.

UIActivityIndicatorView *activityView=[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

    activityView.center=self.view.center;

    [activityView startAnimating];

    [self.view addSubview:activityView];
    [self.view userInteractionEnabled:NO];   //to avoid touch events when activity is on

And to stop the activity indicator use

[activityView stopAnimating];    
[activityView removeFromSuperview];
[self.view userInteractionEnabled:YES];

This is from this link about AV Foundation. and this answer ->

Using KVO, it's possible to be notified for changes of the player status:

player = [AVPlayer playerWithURL:fileURL];
[player addObserver:self forKeyPath:@"status" options:0 context:nil];

In the PLAY button's event add the code to start the `UIActivityIndicator`

This method will be called when the status changes:

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object
                        change:(NSDictionary *)change context:(void *)context {
    if (object == player && [keyPath isEqualToString:@"status"]) {
        if (player.status == AVPlayerStatusReadyToPlay) {
            //DISABLE THE UIACTIVITY INDICATOR HERE
        } else if (player.status == AVPlayerStatusFailed) {
            // something went wrong. player.error should contain some information
        }
    }
}
