仅当键盘处于活动状态时，点击背景以关闭 TextField 键盘

Question

我一直对我设置为十进制键盘的文本字段有问题，因为它的十进制键盘没有 return 键，所以我必须点击背景来关闭它。我只想让它在键盘打开时识别该点击。目前它会在您点击背景时识别它。任何帮助都会非常感谢。

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

    self.view.endEditing(true)
    label.text = "tapped"
}

你可以添加这个扩展，它对我有用：

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }
    @objc func dismissKeyboard() {
        view.endEditing(true)
    }
}

然后把这个self.hideKeyboardWhenTappedAround()放在viewDidLoad

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        view.endEditing(true)
    }

仅当键盘处于活动状态时，点击背景以关闭 TextField 键盘

Tap background to dismiss TextField keyboard only if keyboard is active
