今天在逆向一款经典软件，创建软件里面一个类的对象，调用里面的方法却没有在控制台打印，挺疑惑的

技能讨论

贴出tweak代码
就是LocationRetriever这个类，然后在button的点击事件中创建一个LocationRetriever对象 并调用LocationRetriever的对象方法 在xcode控制台并没有打印，而且用lldb下断点也没反应，通过打印测试（“11111111111”） 可以确定点击事件确实执行了 懂得大神给小弟指点一下。

哎，我的阅读能力有问题。。。。并没有打印什么？

3

只打印了 111111111 所以没贴出来 创建了LocationRetrieve这个类的对象 却没有执行对象方法

4

问题已解决，谢谢各位大神:grinning:

5

解决方法贴一下啦，万一以后有小伙伴遇到哈

6

没脸贴:joy:

7

那低级错误，也算个原因啦

8

LocationRetrieve 少个“r”, 哈哈 也不知道为什么不报错和崩机

9

可以看看%c的原理，估计就是当字符串 NSClassFromString 之类的了:joy:

好的喃，大神，早点休息
