unrecognized selector sent to instance というエラー。

 

問題があったコード

Swift

let tap = UITapGestureRecognizer(target: self, action: "doubleTapped") tap.numberOfTapsRequired = 2 textView.addGestureRecognizer(tap)

1 2 3

let tap = UITapGestureRecognizer(target: self, action: "doubleTapped") tap.numberOfTapsRequired = 2 textView.addGestureRecognizer(tap)

 

修正したコード

Swift

let tap = UITapGestureRecognizer(target: self, action: "doubleTapped:") tap.numberOfTapsRequired = 2 textView.addGestureRecognizer(tap)

1 2 3

let tap = UITapGestureRecognizer(target: self, action: "doubleTapped:") tap.numberOfTapsRequired = 2 textView.addGestureRecognizer(tap)

 

doubleTapped → doubleTapped:

 

これでおk
