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 ()

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
    }
}

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)

    }

使用IQKeyboardmanager，将帮助您解决简单.....

[如何禁用键盘..][1].

import UIKit

class ViewController: UIViewController,UITextFieldDelegate {

   @IBOutlet weak var username: UITextField!
   @IBOutlet weak var password: UITextField!

   override func viewDidLoad() {
      super.viewDidLoad() 
      username.delegate = self
      password.delegate = self
      // Do any additional setup after loading the view, typically from a nib.
   }

   override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
   }

   func textFieldShouldReturn(textField: UITextField!) -> Bool // called when   'return' key pressed. return NO to ignore.
   {
      textField.resignFirstResponder()
      return true;
   }

   override func touchesBegan(_: Set<UITouch>, with: UIEvent?) {
     username.resignFirstResponder()
     password.resignFirstResponder()
     self.view.endEditing(true)
  }
}

下面是关于如何在Xcode 6.1中使用Swift消除键盘的回答:

import UIKit

class ItemViewController: UIViewController, UITextFieldDelegate {

    @IBOutlet var textFieldItemName: UITextField!

    @IBOutlet var textFieldQt: UITextField!

    @IBOutlet var textFieldMoreInfo: UITextField!


    override func viewDidLoad() {
        super.viewDidLoad()

        textFieldItemName.delegate = self
        textFieldQt.delegate = self
        textFieldMoreInfo.delegate = self
    }

                       ...

    /**
     * Called when 'return' key pressed. return NO to ignore.
     */
    func textFieldShouldReturn(textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        return true
    }


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

}

(此信息的来源)。

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)
    }
}
