在故事板:

选择TableView 在右边，选择属性检查器 在键盘部分-选择你想要的解散模式

我发现最好的解决方案包括来自@Esqarrouth的接受答案，并进行了一些调整:

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboardView")
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }

    func dismissKeyboardView() {
        view.endEditing(true)
    }
}

电话响了。cancelsTouchesInView = false是关键的:它确保UITapGestureRecognizer不会阻止视图上的其他元素接收用户交互。

方法解雇键盘()被更改为稍微不那么优雅的解雇keyboardview()。这是因为在我的项目相当旧的代码库中，有很多次已经使用了dismissKeyboard()(我想这并不少见)，导致编译器问题。

然后，如上所述，这个行为可以在各个视图控制器中启用:

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

我在uisearchbar上锻炼。看到我的。

import UIKit

class BidderPage: UIViewController,UISearchBarDelegate,UITableViewDataSource {

     let recognizer = UITapGestureRecognizer()

// Set recogniser as public in case of tableview and didselectindexpath.


    func searchBarTextDidBeginEditing(searchBar: UISearchBar)

    {

        recognizer.addTarget(self, action: "handleTap:")
        view.addGestureRecognizer(recognizer)

    }

    func handleTap(recognizer: UITapGestureRecognizer) {
        biddersearchbar .resignFirstResponder()
    }
    func searchBarTextDidEndEditing(searchBar: UISearchBar)
    {
        view .removeGestureRecognizer(recognizer)

    }

如果你使用滚动视图，它会简单得多。

只需在故事板中交互式地选择解散。

因为我编辑的@King-Wizard的回答被拒绝了，所以发布了一个新的答案。

让你的类成为UITextField的委托并重写touchesBegan。

斯威夫特4

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet var textField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        textField.delegate = self
    }

    //Called when 'return' key is pressed. Return false to keep the keyboard visible.
    func textFieldShouldReturn(textField: UITextField) -> Bool {
        return true
    }

    // Called when the user clicks on the view (outside of UITextField).
    override func touchesBegan(touches: Set<UITouch>, with event: UIEvent?) {
        self.view.endEditing(true)
    }

}

我更喜欢这样一句话:

view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "dismissKeyboardFromView:"))

只要把它放在override viewDidLoad函数中，不管你想让它发生在哪个子类UIViewController中，然后把下面的代码放在你的项目中的一个新的空文件中，名为“UIViewController+dismissKeyboard.swift”:

import UIKit

extension UIViewController {
    // This function is called when the tap is recognized
    func dismissKeyboardFromView(sender: UITapGestureRecognizer?) {
        let view = sender?.view
        view?.endEditing(true)
    }
}
