This is what I got so far. - (IBAction)HUDPanelDictionaryHide:(id)sender{ extern NSPanel HUDPanelDictionary; [HUDPanelDictionary close]; } This obviously does NOT work.

I've figured out how to create a new UI element where I touch and add it using [self.view addSubview:[uilabel reference]]. However, if I tap in the same place, it'll simply add another subview on top of the current one. I am able to create a unique key for each part of the grid I'm making (and thus placing subviews). Is there any way I ...
