title: Zooming in UIScrollView is not smooth
body: <p>I created a minesweeper clone game in iphone. My implementaion of the cells in the grid is this, I created a UIView and added buttons in the UIView and then I added the UIView in a UIScrollView, but every time I zoom out or zoom in using zoomToRect method of UIScrollView the zooming is not smooth and the zoom out was distorted. How can implement smooth zooming in UIScrollView?</p>
