I want to create a magnifying glass type effect in my iPhone app, where the text goes from blurry to not blurry in an animation. Can anyone think of a way to do that? Thanks.

In iOS 6 we finally have the ability to make an image literally blurry, using a CIFilter. So you could, if you really wanted to, make an image of the area to be blurred, blur it with CIFilter, and superimpose that blurred image. Then you could use a timer or CADisplayLink to ask for successive “frames” of the animation, and each time you would do the same thing, only creating a less and less blurred image and showing it.
