libc ++ abi.dylib：以NSException类型的未捕获异常终止（lldb） [英] libc++abi.dylib: terminating with uncaught exception of type NSException (lldb)
问题描述
我正在使用swift编写应用程序，当我在iPhone模拟器上运行测试应用程序时，一切正常，但后来我尝试向右滑动，这是我添加的一个手势，以便转到下一页（查看控制器2）它崩溃并在控制台日志中显示此错误报告。
I'm programming an app in swift and when I run the test app on the iPhone simulator everything works, but then I try to swipe right, which is a gesture that I added for it to go to the next Page(View Controller Two) it crashes and shows this error report in the console log.

推荐答案
CMYR - 如果您已将按钮连接到不再存在的IBAction（或已经存在），也可能发生这种情况已重命名）
CMYR - "his could also happen if you've wired up a button to an IBAction that doesn't exist anymore (or has been renamed)"
如果您遇到此问题，请确保转到Main.storyboard，右键单击黄色方框图标（视图控制器）电话号码顶部，并用黄色标记删除插座。
If you're running into this problem make sure that you go to Main.storyboard, RIGHT click on the yellow box icon (view controller) at the top of the phone outline and DELETE the outlet(s) with yellow flags.
在这样的情况下会发生什么事情，你可能会命名一个动作，然后重命名它。您需要删除旧名称，如果这是唯一的问题将立即开始在SIM！
What happens in instances like this is you probably named an action, then renamed it. You need to delete the old name and if that was the only issue will start right up in sim!
