Make sure the method parameter has a pointer(*) in it.
Example:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath)indexPath {
NSString *movieSelected = [listOfMovies objectAtIndex:indexPath.row];
NSString *msg = [NSString stringWithFormat:@"You have selected %@", movieSelected];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@”Movie Selected”
message:msg delegate:self cancelButtonTitle:@”OK” otherButtonTitles:nil];
[alert show];
[alert release];
}

In the example above, the NSIndexPath must have * symbol .
