找不到崩溃异常原因的类型：EXC_BREAKPOINTSIGTRAP

如何解决找不到崩溃异常原因的类型：EXC_BREAKPOINTSIGTRAP

如果有人能花时间帮助我，我将非常感激！

我现在面临的情况 我试图从扩展中显示一个视图控制器，但应用程序崩溃了，却没有带领我出现错误代码行。

我尝试过的事情：我添加了许多断点，发现如果我不显示表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，将信息正确地加载到表中之后，几秒钟后，崩溃就会发生。

我可以提供的服务：我可以提供完整的崩溃报告：

解决方法

看，您的应用程序在以下位置崩溃了：

Triggered by Thread:  1

并使用

[CALayer layoutSublayers]

看起来像是，您正在不在某个主线程中更新UI

每当您看到这样的内容

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...”。

这将创建一个称为“所有Objective-C异常”的断点。这将在引发异常的那一刻暂停调试器，让您看到导致异常的Apple API的误用。
