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

您还可以添加一个点击手势识别器来重新使用键盘。: D

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let recognizer = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
    backgroundView.addGestureRecognizer(recognizer)
}
    func handleTap(recognizer: UITapGestureRecognizer) {
    textField.resignFirstResponder()
    textFieldtwo.resignFirstResponder()
    textFieldthree.resignFirstResponder()

    println("tappped")
}

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*/
}

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)

    }

斯威夫特3:

扩展选择器作为参数，能够做额外的东西在解散函数和cancelsTouchesInView，以防止扭曲与触摸的其他元素的视图。

extension UIViewController {
    func hideKeyboardOnTap(_ selector: Selector) {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: selector)
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }
}

用法:

override func viewDidLoad() {
    super.viewDidLoad()
    self.hideKeyboardOnTap(#selector(self.dismissKeyboard))
}

func dismissKeyboard() {
    view.endEditing(true)
    // do aditional stuff
}

可以通过在AppDelegate的窗口属性中添加全局点击手势识别器来实现这一点。

这是一种非常全面的方法，对某些人来说可能不是理想的解决方案，但对我来说很有效。请让我知道这个解决方案是否有任何陷阱。

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        // Globally dismiss the keyboard when the "background" is tapped.
        window?.addGestureRecognizer(
            UITapGestureRecognizer(
              target: window, 
              action: #selector(UIWindow.endEditing(_:))
            )
        )

        return true
    }
}
