FXBlurView is a UIView subclass that replicates the iOS 7 realtime background blur effect, but works on iOS 5 and above. It is designed to be as fast and as simple to use as possible.
FXBlurView offers two modes of operation: static, where the view is rendered only once when it is added to a superview (though it can be updated by calling setNeedsDisplay or updateAsynchronously:completion) or dynamic, where it will automatically redraw itself on a background thread as often as possible.
