iOS objc_msgSend崩溃，没有报告或警告

问题描述

我测试我的应用程序，推动它很难，我得到它崩溃（黑屏，图像不保存，回到跳板）。但是，我没有崩溃报告登录控制台。

I am testing my app out, pushing it pretty hard, and I'm getting it to crash (black screen, image doesn't save, drops back to springboard). However, I get no crash reports logged in the console. When I test using profiler all I get is a message saying the target died, but it gives no clues.

在组织者中我得到了设备崩溃日志，它给了我这个我相信告诉我，我发送消息到我已经发布的东西（objc-msgSend + 22）？

In the organiser I got the device crash logs which gives me this which I believe is telling me I'm sending a message to something I've released (objc-msgSend + 22)? Am I on the right track here?

推荐答案

1. 如果您怀疑您的内容过于夸张，请尝试在启用NSZombie的情况下运行您的应用程序。 （）

您可以在控制台中打印回溯。

You can set exception breakpoint to print backtrace in console.
