How to zoom image in iPhone?

Answer 1

You would probably have to use the size property of UIImage, triggered by UIImageView's touchesBegan method.

You can also use animations if you want the zoom effect to be smooth.

Another option could be to place your UIImageView inside a UIScrollView, or use a UIWebView.

Also, I suggest you take a look at the Three20 project. I think TTPhotoView supports zooming.
