SCREEN SHOT OF ERROR
I have been trying to resolve this error for a couple of days. It is a Thread 1: signal SIGABRT error. Any help will be greatly appreciated. The link is a picture of the code.
回答1:
SIGABRT happens when you call an outlet that is not there.
- No view is connected
- Duplicate might be there
Outlets are references to storyboard/xib-based UI elements inside your view controller. Make sure whatever you are trying to call is there.
