推荐答案

当你的程序崩溃时，你可以进入调试器控制台并输入 bt （回溯），它可以让您了解崩溃时正在执行的代码。顶级项目可能不是您的代码，但如果您继续向下移动，您最终应该会在那里看到您的内容。

When your program crashes, you can go to the debugger console and type bt (backtrace) which will give you an idea of what code was being executed at the time of the crash. The top level items may not be your code, but if you keep moving down you should see something of yours in there eventually.

如果您的代码没有任何调用，那么这些SIGABRT错误通常与您的xib文件有关，在xib中会丢失或重命名或以其他方式更改未在代码中反映的文件。

If there aren't any calls from your code then these SIGABRT errors are often related to your xib files, there will be something missing or renamed or otherwise changed in a xib file that hasn't been reflected in your code.
