I wouldn’t use UIButtons at all for this. I’ll start by assuming you’re talking about one tap at a time, ie that you don’t need to be able to tap more than one cell simultaneously. You finish one gesture then start another. So make your board a UIView, the whole thing, one view, and attach one single, one double and one long press gesture recogniser to it, and configure them appropriately so they allow each other to run or not, depending on how your game works. Then all you have to do when you have a gesture which is recognised is to take the coordinates of the gesture, and work out which virtual ‘cell’ that represents on your board. This is totally scalable from 1x1 cells to however many x however many, the board dimensions are just a property of your custom view. You can easily draw your own highlight as the cell is tapped and make it look like a button, or probably better look not like a button but like a cell in your game being tapped. Just make sure your cell to coordinates and coordinates back to cell logic is in one place so the drawing and gameplay are using the same transformation as the gesture recognisers. _______________________________________________ Do not post admin requests to the list.
