Mutated version of Wax (https://github.com/probablycorey/wax/)
Support method override and direct method call from Obj-C code, which gives you the ability to dynamically change the behavior of a running iOS application.
The patch is a zip file contains patch.lua and other lua codes. The sample code can be found at /patch folder.
The sample iOS project loads the patch from a url (which you probably want to change in AppDelegate.m) before launch.
The Original.png and Patched.png shows the difference.
