使用Swift触摸任意位置以关闭iOS键盘

override func viewDidLoad() {    super.viewDidLoad()    //Looks for single or multiple taps.     let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboard")    //Uncomment the line below if you want the tap not not interfere and cancel other interactions.    //tap.cancelsTouchesInView = false    view.addGestureRecognizer(tap)}//Calls this function when the tap is recognized.@objc func dismissKeyboard() {    //Causes the view (or one of its embedded text fields) to resign the first responder status.    view.endEditing(true)}

如果要多次使用此功能，这是另一种执行此任务的方法

UIViewControllers

// Put this piece of pre anywhere you likeextension 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)    }}

现在在每个中

UIViewController

override func viewDidLoad() {    super.viewDidLoad()    self.hideKeyboardWhenTappedAround() }

此功能作为标准功能包含在我的存储库中，其中包含许多类似这样的有用的Swift扩展，请查看：https
