    [[_items objectAtIndex:indexPath.row] objectForKey:@"redirect_url"]]];
    NSData *data = [NSData dataWithContentsOfURL:url];
    audioPlayer = [[AVAudioPlayer alloc] initWithData:data error:nil]; 
    // Now we are assigning it in an instance variable thus ARC will not deallocate it.
    [audioPlayer play];

Answer 1

The right way to do it is this:

NSString *urlString = [NSString stringWithFormat:@"http://bla.bla/bla/%@/%@-%@.mp3", @"upperCaseString", @"combinedString", @"wordIndex"];
NSURL *url = [NSURL URLWithString:urlString];

Edit:

The final code will look like this:

-(void)getWord:(NSString*)upperCaseString :(NSString *)combinedString :(NSString *)wordIndex
{
    NSString *urlString = [NSString stringWithFormat:@"http://quicklanguages.com/materiales/quicklanguages/audios/%@/%@-%@.mp3",@"upperCaseString", @"combinedString", @"wordIndex"];
    NSURL *url = [NSURL URLWithString:urlString];
    //  [tweetSheet setInitialText:[NSString stringWithFormat:@"%@", 
    [[_items objectAtIndex:indexPath.row] objectForKey:@"redirect_url"]]];
    NSData *data = [NSData dataWithContentsOfURL:url];
    audioPlayer = [[AVAudioPlayer alloc] initWithData:data error:nil]; 
    // Now we are assigning it in an instance variable thus ARC will not deallocate it.
    [audioPlayer play];
}
