MethodSwizzling - hewigovens/hewigovens.github.com GitHub Wiki

definition from Cocoadev

The Objective-C runtime lets you modify the mappings from a selector (method name) to an implementation (the method code itself). This allows you to "patch" methods in code you don't have the source to (AppKit, FoundationKit, etc). Unlike creating a category method with the same name as the original method (effectively replacing the original method), MethodSwizzling lets your replacement method make use of the original method, almost like subclassing.
