我一直在到处找这个,但我似乎找不到。我知道如何解雇使用Objective-C键盘,但我不知道如何使用Swift?有人知道吗?
当前回答
以下是如何通过点击其他地方来消除键盘,使用Swift 5只需两行。
(我讨厌添加另一个答案,但由于这是谷歌上的顶级结果,我将帮助像我这样的新手。)
在你的ViewController.swift中,找到viewDidLoad()函数。
加上这两行:
let tap: UIGestureRecognizer = UITapGestureRecognizer(target: self.view, action: #selector(UIView.endEditing))
view.addGestureRecognizer(tap)
其他回答
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)。
Dash的回答是正确的。一个更“焦土”的方法是调用view. enditing (true)。这将导致视图及其所有子视图resignFirstResponder。如果您没有想要删除的视图的引用,这是一种俗气但有效的解决方案。
请注意,我个人认为你应该有一个引用的视图,你想要有辞职第一响应者. enditing (force: Bool)是一个野蛮的方法;请不要使用它。

[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.

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

return true;
}
override func touchesBegan(_: Set<UITouch>, with: UIEvent?) {
username.resignFirstResponder()
password.resignFirstResponder()
self.view.endEditing(true)
}
}
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")
}
//Simple exercise to demonstrate, assuming the view controller has a //Textfield, Button and a Label. And that the label should display the //userinputs when button clicked. And if you want the keyboard to disappear //when clicken anywhere on the screen + upon clicking Return key in the //keyboard. Dont forget to add "UITextFieldDelegate" and
//"self.userInput.delegate = self" as below
import UIKit
class ViewController: UIViewController,UITextFieldDelegate {
@IBOutlet weak var userInput: UITextField!
@IBAction func transferBtn(sender: AnyObject) {
display.text = userInput.text
}
@IBOutlet weak var display: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
//This is important for the textFieldShouldReturn function, conforming to textfieldDelegate and setting it to self
self.userInput.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//This is for the keyboard to GO AWAYY !! when user clicks anywhere on the view
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
//This is for the keyboard to GO AWAYY !! when user clicks "Return" key on the keyboard
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
}
