cocoa - NSApplicationMain() 中的 strlen 发生奇怪的 cocoa 崩溃

Question

几天前我关闭了我的 xcode 项目，当我回来时，它一直崩溃!我没有更改任何代码，所以我不知道发生了什么。我在 NSApplicationMain() 方法内的 strlen 上收到 EXC_BAD_ACCESS (code=1, address=0x0) 并查看错误堆栈，看起来我的应用程序没有甚至推出了!

这是错误堆栈

Answer 1

您的应用程序的持久状态似乎已以某种方式损坏。如果您进入 ~/Library/Saved Application State/ 目录并删除您的应用程序的目录，它应该会修复它。
