title: Objective-C Runtime: How to remove a method from a class?
body: <p>In the <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ObjCRuntimeRef/Reference/reference.html" rel="nofollow">Objective-C Runtime Reference</a>, I see <code>class_addMethod</code> but not <code>class_removeMethod</code>. How do I dynamically remove a method?</p>
  
  <p>Also, does <code>class_addMethod</code> add an instance method or a class method?</p>
