我一直在寻找这个，但是我似乎找不到。我知道如何使用来关闭键盘，Objective-C但是我不知道如何使用Swift？有人知道吗？

回答：

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 code anywhere you like
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)
    }
}

现在在每个中UIViewController，您所需要做的就是调用此函数：

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
