PhotoView aims to help produce an easily usable implementation of a zooming Android ImageView.
Out of the box zooming, using multi-touch and double-tap.
Scrolling, with smooth scrolling fling.
Works perfectly when using used in a scrolling parent (such as ViewPager).
Allows the application to be notified when the displayed Matrix has changed. Useful for when you need to update your UI based on the current zoom/scroll position.
Allows the application to be notified when the user taps on the Photo.

This is a drop-in replacement for Apples Reachability class. It is ARC compatible, uses the new GCD methods to notify of network interface changes.
In addition to the standard NSNotification it supports the use of Blocks for when the network becomes reachable and unreachable.
Finally you can specify wether or not a WWAN connection is considered “reachable”.
