如果你想解散键盘，当你想去下一个按钮动作或任何地方。

你可以简单地添加下面的行，替换你的文本字段名称。

billTextField.endEditing(真正的) 或 billTextField.resignFirstResponder ()

你可以使用swift

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

}

Swift 5只要两行就够了。添加到你的viewDidLoad应该工作。

 let tapGesture = UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing))
 view.addGestureRecognizer(tapGesture)

如果你的点击手势阻止了一些其他的触摸，那么添加这一行:

tapGesture.cancelsTouchesInView = false

如果你想解散键盘，当你想去下一个按钮动作或任何地方。

你可以简单地添加下面的行，替换你的文本字段名称。

billTextField.endEditing(真正的) 或 billTextField.resignFirstResponder ()

添加这个扩展到你的ViewController:

  extension UIViewController {
// Ends editing view when touches to view 
  open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesBegan(touches, with: event)
    self.view.endEditing(true)
  }
}

我得到了你

override func viewDidLoad() {
    super.viewDidLoad() /*This ensures that our view loaded*/
    self.textField.delegate = self /*we select our text field that we want*/   
    self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: Selector("dismissKeyboard")))
}

func dismissKeyboard(){ /*this is a void function*/
    textField.resignFirstResponder() /*This will dismiss our keyboard on tap*/
}
