ios - Xcode 8.1 发布 APP 崩溃 libobjc.A.dylib objc_msgSend

Question

APP在Xcode8.1上直接安装在手机上所有版本上运行都没有任何问题，发布.ipa到第三方平台安装，在iOS9.3以下没有任何问题，但是当我提交的时候将AppStore和testfight安装到手机上，在iOS9.3以下版本会出现异常闪退，谁遇到过同样的问题呀，解决了，我在使用Xcode7发布的时候没有遇到过这个问题。

谁能告诉我如何追踪到它？

我在 Crashlytics 中遇到如下所示的崩溃。

ObjC 运行时和/或自动释放操作中的崩溃几乎总是悬空指针。

我非常怀疑这与环境有关。更像是，只有您在正常开发过程中看不到的代码路径/边缘情况。我将从 NSZombies 开始，它真的很有帮助。

我还建议查看您的 Crashlytics 崩溃，以查找奇怪的无法识别的选择器崩溃或运行时代码中的其他问题。它们都可能与相同的根本原因有关。
