如何阅读 Xcode 崩溃报告？

How do I read an Xcode crash report?

提问by Nathan Mackinnon

I have an app that I just submitted it to the app sore (The app was developed for me as I do not know iOS development I do however know know other coding languages). Apple rejected the app saying that is crashed (The strange thing is is never crashed in all tests I did, probably about 50!) I got their crash log, Symbolicated it in Xcode and get this as a result. The only problem is that I don't understand this either. I was wondering if someone can explain what this means, Where abouts in my code that this error is and how I can fix it.

我有一个应用程序，我刚刚将它提交给应用程序痛处（该应用程序是为我开发的，因为我不知道 iOS 开发，但我知道其他编码语言）。Apple 拒绝了该应用程序，称该应用程序已崩溃（奇怪的是在我所做的所有测试中从未崩溃过，可能大约有 50 次！）我得到了他们的崩溃日志，在 Xcode 中对其进行了符号化，结果得到了这个。唯一的问题是我也不明白这一点。我想知道是否有人可以解释这意味着什么，这个错误在我的代码中的位置以及我如何修复它。

This kind of question have been asked many more times. Look at the below question.

这种问题已经被问过很多次了。看看下面的问题。

understanding crash report

了解崩溃报告

in the console report you have

在控制台报告中，您有

Exception Type:  EXC_CRASH (SIGABRT)

This means you are using some thing which is deallocated.

这意味着您正在使用一些已解除分配的东西。

Here are some tutorials how to debug the code when any crash occur, by raywenderlich.

You say you symbolicated it in Xcode, but I see unresolved addresses in frames 1, 2, 15, and 16 of the stack trace, in code loaded from something called “Chapter3 Framework”, which must be part of your app since it's not an Apple framework. You need to get the .dSYMfile for the version of “Chapter3 Framework” in your app.

你说你在 Xcode 中对它进行了符号化，但我在堆栈跟踪的第 1、2、15 和 16 帧中看到未解析的地址，在从称为“第 3 章框架”的东西加载的代码中，它必须是你的应用程序的一部分，因为它不是苹果框架。您需要.dSYM在您的应用中获取“Chapter3 Framework”版本的文件。

Frame 3 of the stack trace is in -[UIApplication _handleApplicationSuspend:eventInfo:]and frame 2 is in some function in “Chapter3 Framework”. The tester at Apple probably switched away from your app, which puts it in the background. When an app enters the background, it sends the message applicationDidEnterBackground:to the app delegate. So I guess frame 2 is in your app delegate's applicationDidEnterBackground:method. Did you test switching away from your app? Did you test switching away from it lots of times, with your app in different states?

堆栈跟踪的第 3-[UIApplication _handleApplicationSuspend:eventInfo:]帧位于“第 3 章框架”中的某个函数中，第 2 帧位于某个函数中。Apple 的测试人员可能会离开您的应用程序，将其置于后台。当应用程序进入后台时，它会将消息发送applicationDidEnterBackground:给应用程序委托。所以我猜第 2 帧在您的应用程序委托的applicationDidEnterBackground:方法中。您是否测试过离开您的应用程序？您是否在应用处于不同状态的情况下测试过多次关闭它？

The crash report says it crashed on iOS 5.0.1. Did you test switching away from your app on iOS 5.0.1?

崩溃报告说它在 iOS 5.0.1 上崩溃了。您是否在 iOS 5.0.1 上测试过离开您的应用程序？

The crash report says it crashed on an “iPhone4,1”, which is an iPhone 4S. Did you test switching away from your app on an iPhone 4S?

崩溃报告说它在“iPhone4,1”上崩溃了，这是一部 iPhone 4S。您是否在 iPhone 4S 上测试过退出应用程序？

Did you test switching away from your app on iOS 5.0.1 on an iPhone 4S?

您是否在 iPhone 4S 上测试过从 iOS 5.0.1 上的应用程序切换？

Did you test switching away from your app on a clean install of your app on iOS 5.0.1 on an iPhone 4S?

您是否测试过在 iPhone 4S 上的 iOS 5.0.1 上全新安装您的应用程序时切换离开您的应用程序？

15  Chapter3 Framework             0x000024d6 0x1000 + 5334
16  Chapter3 Framework             0x0000246c 0x1000 + 5228

You don't seem to have the symbols in a place where Xcode (Spotlight) can find it. You need the .app and .dsym files for the binary this crashlog is from.

您似乎在 Xcode (Spotlight) 可以找到它的地方没有符号。您需要此崩溃日志来自的二进制文件的 .app 和 .dsym 文件。

Identifier:      Chapter3 Framework
Version:         ??? (???)

This looks like there's no version number available.

这看起来没有可用的版本号。
