swift - 使用 UI 工具栏将 'Done' 按钮添加到键盘

Question

我有一些 TextView ，我希望能够有一个完成按钮。我添加了一个 UI 工具栏，并将其连接为完成按钮的 socket 和 IB 操作

工具栏没有显示？我错过了什么？

    func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
     ingredientsTextField.inputAccessoryView
    = keyboardToolbar
    return true
}

@IBAction func didClickDoneButton(_ sender: UIBarButtonItem) {
    ingredientsTextField.endEditing(true)
}

Answer 1

可能是你创建的工具栏有误，请检查一下

 func textViewShouldBeginEditing(_ textView: UITextView) -> Bool {

        self.addAccessoryView()

        return true
    }


    func addAccessoryView() -> Void {
        let toolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 44))
        let doneButton = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonTapped(button:)))

        let flexibleSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)

        toolBar.items = [flexibleSpace,doneButton]
        toolBar.tintColor = UIColor.red

        self.textView.inputAccessoryView = toolBar
    }
    func doneButtonTapped(button:UIBarButtonItem) -> Void {
        // do you stuff with done here
    }
