仅当键盘处于活动状态时，点击背景才能关闭TextField键盘

Question

我一直有一个问题，我设置为十进制键盘的文本字段，因为它的十进制键盘没有返回键，所以我必须点击背景来关闭它。我想只允许它识别键盘是否打开时点击。目前，只要你点击背景，它就能识别它。任何帮助都会非常棒。

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

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

您可以添加此扩展程序，它对我有用：

trapframe

然后将此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) } } 放入self.hideKeyboardWhenTappedAround()

viewDidLoad
