ios 应用程序在启动时发生奇怪的崩溃

Question

我的项目名为 OBI，从 Xcode 启动时运行良好，但当我创建 .ipa 文件时，它会崩溃并提供日志。在项目中没有名称为:Mutex、DelayedPointerDeletionManager 或 MemoryManager 的类，因此我无法理解此异常的来源。

如果有任何帮助或挖掘方向，我将非常高兴

编辑最后我找到了导致这个异常的原因。build设置中的 symbol striping 选项，在我将其从 all symbols 更改为 debug symbols 后，一切都变得很好。

当 iOS 将您的类加载到内存中时，这会在动态加载器中崩溃。此过程的一部分是在任何实现该方法的类上调用 +load。

一种可能是您在 +load 中做了太多工作，并因“未能及时启动”而被杀死。提供完整的崩溃日志将显示是否属于这种情况。
