What to replace a UIButton to improve frame rate?
<p>I created a minesweeper clone game and I made a 30 x 30 grid of cells. Now in my initialize design, I planned to use UIButton for each cell so  that I can use its touchDown and touchUpInside. But my problem is using UIButton makes the game slow in zooming and especially in loading or adding each cell(900 pcs) in a UIView.</p>

<p>Now I'm planning to use images instead of UIButton and I heard about CALayer for easy animation. Can you suggest how can I use this CALayer for my implementation or replacement of UIButton?</p>

<p>Thanks.</p>
