Question

我正常设置带有数字键盘的文本字段以及解除键盘和resignFirstResponder操作，但是当我点击背景时，数字键盘会变为普通键盘，然后当我再次点击背景键盘时，键盘会自动关闭 - 陌生！如何只需点击一下即可关闭数字键盘？

self.textField.delegate = self
        textField.keyboardType = UIKeyboardType.DecimalPad

 @IBAction func tapBackground(sender: AnyObject) {
        view.endEditing(true)
    }

@IBAction func viewTapped(sender: AnyObject) {
       textField.resignFirstResponder()
    }

尝试以下操作可能会对您有所帮助：）

override func viewDidLoad() {
        super.viewDidLoad()
        let tap = UITapGestureRecognizer(target: self, action: "handleTapGesture:")
        tap.delegate = self
        self.view.addGestureRecognizer(tap)

    }
// MARK: - UITapGestureRecognizer
    func handleTapGesture(gesture : UITapGestureRecognizer) {
        self.view.endEditing(true)
    }

    func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool
 {
return true
 }

数字键盘在swift中调到普通键盘
