At the moment I’m working on an iPad explore game which has a hexagon tile map.
I’ve created a UIScrollView that contains a background view (the game map) and buttons in the form of hexagons (for interaction). I add every UIButton to the view via addSubview.
But… when I add more than 100 buttons the view gets laggy (no surprise here). But what should I do to solve this?
Example:

Adding UIButtons isn’t the way to go here. You should probably draw the “buttons” in a custom -drawRect: method and use -touchesEnded:withEvent: to decide what the user wanted to do.
