I have defined this in code: @property (nonatomic, weak) IBOutletCollection(UITableViewCell) NSSet * certaintyCells; and synthesized. I made absolutely sure that this controller is used in story board, and connected three cells to this collection. Next, in the didSelectRowAtIndexPath: method call, I added this code, with NSLog added for debugging: NSLog(@"Certainty Cells: %@",certaintyCells); for (UITableViewCell * cell in certaintyCells) { [cell.textLabel setTextColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1]]; [cell setSelectionStyle:UITableViewCellSelectionStyleBlue]; } The output is this: Certainty Cells: (null) And of course, behaviour expected does not happen. Any ideas as to why this is happening? I did make sure that I am using static cells, and not dynamic prototypes. As a side note, these three cells are also connected to (working) IBOutlets of their own. Thanks,
