Play a Sound when a cell is tapped

Question

I'm working on a project where when a cell in a tableview is pressed, a sound will play. I have put my sounds into an array, like so:

- (void)viewDidLoad
{
 [super viewDidLoad];
//Data
soundArray = [NSArray arrayWithObjects:
              [Sounds soundOfCategory:@"Sound" name:@"clipOne"],
              [Sounds soundOfCategory:@"Sound" name:@"clipTwo"],
              [Sounds soundOfCategory:@"Sound" name:@"clipThree"],
              nil];
//Reload the table
[[self tableView] reloadData];
}

I'm using the following to play the sound:

 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:    (NSIndexPath *)indexPath{

static NSString *cellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}

//Create new Sound Object
Sounds *sound = nil;
sound = [soundArray objectAtIndex:indexPath.row];

//Configure the cell
[[cell textLabel]setText:[sound name]];
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];

return cell;
}

-(void)PlayClip:(NSString *)soundName
{
NSString *path = [[NSBundle mainBundle] pathForResource:soundName ofType:@"mp3"];
AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL     fileURLWithPath:path] error:NULL];

[theAudio play];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath     *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[self PlayClip:[soundArray objectAtIndex:indexPath.row]];
}

But with no luck. I receive the error : * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Sounds length]: unrecognized selector sent to instance 0xa35d720'

What is the issue? Is there a better way to play the sound? I'm new to working with tableviews, so please forgive my ignorance.

Thanks!

You have a problem in the last line of your code:

[self PlayClip:[soundArray objectAtIndex:indexPath.row]]; // PlayClip:(NSString *)

[soundArray objectAtIndex:indexPath.row] returns Sounds not NSStrintg .

I think it should be:

[self PlayClip:[[soundArray objectAtIndex:indexPath.row] name]];
