AVAudioPlayer Freezes the UI when new sound is played

I am new to iOS and I was searching fix for this issue since morning and didn't find the solution yet, I have more than 6000 sound files online which i want to play using AVAudioPlayer when user click on the cell, so i implemented it in didSelectRowAtIndexPath: like this :

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
     NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@", [soundsArray objectAtIndex:(int)indexPath.row]];
     NSData *soundData = [NSData dataWithContentsOfURL:url];
     _audioPlayer = [[AVAudioPlayer alloc] initWithData:soundData  error:NULL];
        [_audioPlayer play];
    }

the problem is, whenever i click on any row, the whole UI freezes till the time it takes to load the complete sound file from internet, for larger files , it takes longer.

I tried with AVPlayer and it is working fine, but I need AVAudioPlayer becouse it seems easy to me to work with -(void)AVAudioPlayerDidFinishPlaying:(AVAudioPlayer *)Player successfully:(BOOL)flag

thats why I want to implement it with AVAudioPlayer

I hope you understood my problem, Sorry for my bad English.

Never use 

 NSData *soundData = [NSData dataWithContentsOfURL:url];

this will block your UI.

You need to use NSURLSession to download data asynchronously.
