EEZoomableImageView

Provides full screen zooming ability to UIImageView like instagram.

What does EEZoomableImageView do?

Gives full screen zooming ability to UIImageView with no additional code.

It handles number of the touch changes on the screen. There is no weird behaviour like jumping image's center when user removes one finger from the screen, as far as I know. :squirrel:
