[iOS]混淆-类名混淆

使用runtime混淆类名

objc_runtime_name属性可以在编译时，将Class或Protocol指定为另一个名字，并且新名字不受命名规范制约，可以以数字开头。

脚本如下：

#encoding:utf-8 # 支持中文输入
import re
import os
import string
import random
s = os.sep
 
##获取当前工作目录
root = os.path.abspath('.')
#需要忽略的文件后缀
ignoredTrail = [".py",".c"]
#需要忽略的文件夹
ignoredDirPath   = ["lib",".git"]
#需要匹配的文件后缀
containTrail   = [".h",".m"]
 
 
#获取文件名和后缀
def getFileNameAndExt(filename):
 (filepath,tempfilename) = os.path.split(filename);
 (shotname,extension) = os.path.splitext(tempfilename);
 return shotname,extension
 
#是否是需要根据后缀忽略的文件
def isIgnoredByTrail(filePath):
  file = getFileNameAndExt(filePath)
  for trail in ignoredTrail:
    if file[1] == trail:
      # print "忽略文件:" + filePath
      return bool(1)
  return bool(0)
 
#是否是需要根据后缀匹配的文件
def isContainByTrail(filePath):
  file = getFileNameAndExt(filePath)
  for trail in containTrail:
    if file[1] == trail:
      # print "忽略文件:" + filePath
      return bool(1)
  return bool(0)
  
#是否根据文件夹路径葫芦
def isIgnoredByDirPath(dirpath):
  for path in ignoredDirPath:
    if string.find(dirpath,path) != -1:
      # print "忽略目录：" + dirpath
      return bool(1)
    else:
      # print "匹配目录：" + dirpath
      continue
  return bool(0)
 
#获取所有文件名
def getAllFiles(path):
 allfile=[]
 for dirpath,dirnames,filenames in os.walk(path):
  # print 'dirpath: ' + dirpath 
  if isIgnoredByDirPath(dirpath):
    continue
     
  for name in filenames:
    if isIgnoredByTrail(name):
      continue
    elif isContainByTrail(name):
      allfile.append(os.path.join(dirpath, name))
    
 return allfile
 
 
#获取所有XIB文件名
