ios - 无法找到崩溃的原因 - 异常类型：EXC_BREAKPOINT (SIGTRAP)
问题描述
如果有人能花时间帮助我，我将不胜感激！！！
我现在面临的问题是 我试图从扩展中展示一个视图控制器，但应用程序在没有引导我出现错误代码行的情况下崩溃了。
我尝试了什么： 我添加了许多断点，发现如果我不显示表格视图控制器来显示正确的信息，则不会崩溃。但是在演示之后，在表格中正确加载信息之后，几秒钟后，崩溃发生了。
我可以提供什么： 我可以提供完整的崩溃报告：

解决方案
每当你看到这样的东西
1 libobjc.A.dylib 0x19825fbcc objc_exception_throw + 55
您应该转到 Xcode 中的断点选项卡，单击 + 按钮，然后单击异常断点...
这将创建一个名为“所有 Objective-C 异常”的断点。这将在抛出异常时暂停调试器，让您看到导致异常的 Apple API 的确切滥用。
