UITextViewにてPlaceholderを実装する

More than 5 years have passed since last update.

UITextViewにはUITextFieldのようにPlaceholderが設定できませんので、自作する必要があります。まず、UITextViewを作り、その上にLabelを置きます。TextViewに入力されているかどうかで、このLabelを非表示にすれば、Placeholderとして動きます。

    //textviewがフォーカスされたら、Labelを非表示
    func textViewShouldBeginEditing(textView: UITextView) -> Bool
    {
        lbl.hidden = true
        return true
    }

    //textviewからフォーカスが外れて、TextViewが空だったらLabelを再び表示
    func textViewDidEndEditing(textView: UITextView) {

        if(textView.text.isEmpty){
            lbl.hidden = false
        }
    }
