我知道，也知道怎么做。但我现在面对的是非常非常困惑的，至少对我来说是如此

背景我有一个多账户应用程序，用户可以同时登录多个账户

该应用程序在只有一个帐户的情况下运行良好，但当用户真正登录越来越多的帐户时，该应用程序也变得越来越容易受到攻击，随机崩溃，但主要发生在

AppLaunch

上。不是8badf00d，而是

EXC\u坏访问（SIGSEGV）/KERN\u无效地址

代码体系结构

Objective-C

-应用程序级，包括用户界面。
|

Objective-C&C++

-帐户上下文，包括登录逻辑。
|

C++

-网络/通信级别，包括套接字

通知和委派都在级别之间使用

复制双击Home（主页）按钮，向外滑动应用程序以将其关闭，然后点击应用程序图标以重新启动。通过

TouchId

后，应用程序将登录帐户，并随机崩溃，导致许多不同的崩溃日志。无论设备是iPhone 6s plus还是iPhone 5s/5c/5、iOS 8还是iOS 9
内存使用率不高，只有几十MB
第一号坠机日志事故日志第二号事故日志第三号事故日志第4号事故日志第5号虽然我手头有日志，但我仍然不知道如何解决它。可能
地址空间
已经变脏了？强制/无意地修改C++级别？

提前感谢。
这些看起来都像是代码中的不同bug。无法猜测。一种可能的情况是，您正在某处存储过时或未初始化的指针，因为
objc\u msgSend
的目标显然无效。NSZOMBOSS的缺乏也暗示了C++中的“宇宙”问题。有很多线吗？一个线程是否释放了另一个线程使用的资源？添加更多代码<代码> NSCORE（）/CUT>来跟踪应用程序的行为，以帮助找出原因。@ MyBDNILO是的，C++是可疑的。@ TROJANFOE，我不这样认为：请看这里
