IOS obtains the instance method list of a class.

To be referenced:

# Import <Foundation/nsobjcruntime. h>

# Import <objc/runtime. h>

Implementation

 

Class currentclass = [common class];

 While (currentclass ){

 Unsigned int methodcount;

 Method * methodlist = class_copymethodlist (currentclass, & methodcount );

 Unsigned int I = 0;

 For (; I <methodcount; I ++ ){

 Nslog (@ "% @-% @", [nsstring stringwithcstring: class_getname (currentclass) encoding: nsutf8stringencoding], [nsstring stringwithcstring: sel_getname (method_getname (methodlist [I])
Encoding: nsutf8stringencoding]);

 }

  

 Free (methodlist );

 Currentclass = class_getsuperclass (currentclass );

 }

(Smking: I tried it. It is indeed feasible, and in objc/runtime. h. Search for class_copymethodlist in the help document. You can see a considerable number of runtime methods. You can also find a way to replace existing classes. In the runtime process, this allows you to intercept events, you can traverse the methods of this class and then replace a special method to invalidate the purpose .)
