我正在尝试调试我的应用程序界面,并在启动时立即崩溃:
libc++abi.dylib: terminating with uncaught exception of type NSException
当我在调试窗格中键入bt
时

有没有办法可以获得比这更有用的信息来解决我的问题。我已经在this页面上尝试了所有内容。
有关如何调试Interface Builder文档的任何提示?
答案 0 :(得分:0)
事实证明我抛出了unrecognized selector sent to instance 0xABC123
个异常。我之所以发现这是因为我使用了内联闭包:
NSSetUncaughtExceptionHandler { exception in
print(exception)
print(exception.callStackSymbols)
}
在我的应用程序结束时(_:didFinishLaunchingWithOptions :)在我的AppDelegate中。由于某种原因,符号任何异常断点都没有为我提供相同数量的细节。
