iphone - UIImageView zoom programmatically

Using CATransition, can I zoom an image view in 开发者_如何学PythoniPhone? Is it possible?

You could use a UIScrollView and its zoomToRect: method.

See: http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIScrollView_Class/Reference/UIScrollView.html

Or... you should use a UIWebView (thats what I did in "Seriously Good! Gluten Free"). You can put in images in HTML code and you get all of the zoom, pan and etc for free! :) And it will work with all versions of the SDK.
