Answer 1

有时 xcode 不会使您的崩溃报告可读（出于某种原因），如果是这样，您可以执行以下步骤：

• 查找创建此错误的相应存档。您可以通过转到组织者并右键单击存档并执行“在查找器中显示”来完成此操作。
• 打开存档（显示包内容）并将应用程序（在产品/应用程序中）和 dSym（在 dSyms 中）复制到临时文件夹。
• 打开终端并转到临时文件夹。
• 打开“/Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gdb/gdb-arm-apple-darwin $(APPNAME).app/$(APPNAME)”
• 这将给出有关框架的各种警告，忽略它们。
• 执行以下操作： set print asm-demangle on
• 并且： set print symbol-filename on
• 然后： p/a {崩溃日志文件中的地址}

这将为您提供堆栈中的类和函数。

首先找到崩溃的负责线程。从你的日志来看，崩溃的线程似乎是6（崩溃的线程：6）。然后你必须去函数回调堆栈（看看顶部），找出负责的框架及其CoreFoundation，方法是[__NSArrayM insertObject:atIndex:]。您在这里做错了什么。去检查一下。
