指向@implementation的EXC_BAD_ACCESS报错？

Question

1.如题，程序崩溃指向@implementation那一行。查阅资料得知，问题产生原因是向向已经销毁的对象发送消息，内存方面问题。
2.按照网上的方法，设置僵尸对象，说是控制台会打印出出错信息，我这没有。。。
3.还有就是通过shift + cmd + b 来分析可能出错的代码，我这也没用、

请教下各位，这种问题该怎么处理？有什么方法才能然我看到出错的问题，定位到问题代码呢？

-------------------------------控制台没有任何信息...截图如下------------------------

---------------------控制台并没有输出任何错误信息-------------------
代码写的太丑了，先不放了，怕被喷。。。下面这个信息你看有用吗

Answer 1

请尝试使用下面的方法找到是哪个变量出现了问题

1. 在Xcode 中，通过快捷键 command+7 进入断点界面。

2. 点击左下角的“+”，并通过添加全局异常断点，

3. 运行程序。

如果无法通过上面方案解决问题，请把相关代码和异常截图贴出来。

Answer 2

我也遇到了相同的问题 ，原因是创建了连个含有地图的页面，在定位的时候发生问题

大神，你去年这个问题最后怎么解决的呀？
