[ios] storyboard IBAction 동작 안할 때

가끔 storyboard를 가지고 작업 하다 보면….

IBAction이 호출 되지 않을 때 selector가 잘못 지정 되어있는지 확인 해볼 필요가 있다.
필자는 connections 해당하는 제스쳐에 해당하는 selector가 선언이 되어 있지 않아  호출 되지 않았다.

Main.storyboard를 코드로 열고  tapGestureRecognizer 에
connections, action tag를 작성 하여 이슈를 해결.

If you run into trouble which IBAction’s selector dose not called made from  storyboard, open *.storyboard file by code viewer and check IBAction’s connections tag has proper action context.

action tag’s ‘destination’ attribute  is viewController’s id, id is own (it must be unique)
