[Swift]UIViewにaddGestureRecognizerしようとしてつまずいた話

5
Last updated at Posted at 2019-07-30

問題

UIViewにUITapGestureRecognizerをaddGestureRecognizerしようとしてもできなかった

前提

・isUserInteractionEnabled = true
・UIViewもnilではなかった

解決方法

addGestureRecognizer(.init(target: self, action: #selector(tapped)))

initを直したら動きました

addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tapped)))

最後に

今思うとaddGestureRecognizerなので、.initで書いたらサブクラスのUITapGestureRecognizerではなく,スーパークラスのUIGestureRecognizerが呼ばれるので、それはそうですよねというお話(引数が同じなのですっかりハマってしまいました。😇😇
