onLeave中如何获取到self类本身的实例变量

• 思路：onEnter时，把self变量赋值保存给this.xxx，onLeave时去读取即可

• 代码

  Interceptor.attach(curMethod.implementation, {
    onEnter: function(args) {
        this.argSelfObj = argSelfObj
        ...
    },
  
    onLeave: function (retval) {
      var retValObj = ObjC.Object(retval);
      var retValObjStr = retValObj.toString();
      console.log("onLeave: retValObj=" + retValObj + ",retValObjStr=" + retValObjStr)
      const curSelfObj = this.argSelfObj
      console.log("curSelfObj=" + curSelfObj)
    }
  })
  

• 输出

  ==================== -[NSXPCConnection setExportedObject:] ====================
  argSelfObj:  <ACTrackedXPCConnection: 0x154907c50> connection to service named com.apple.accountsd.accountmanager
  onLeave: retValObj=nil,retValObjStr=nil
  curSelfObj=<ACTrackedXPCConnection: 0x154907c50> connection to service named com.apple.accountsd.accountmanager
