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?

Swift 5只要两行就够了。添加到你的viewDidLoad应该工作。
let tapGesture = UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing))
view.addGestureRecognizer(tapGesture)
如果你的点击手势阻止了一些其他的触摸,那么添加这一行:
tapGesture.cancelsTouchesInView = false

如何解散键盘时,你点击任何地方关闭它
//Setup dismiss keyboard gesture
let tap = UITapGestureRecognizer(target: self, action: #selector(UIInputViewController.dismissKeyboard))
view.addGestureRecognizer(tap)
}
//Calling this function when the tapped
@objc func dismissKeyboard() {
view.endEditing(true)
}
你可以使用swift
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
view.endEditing(true)
}
//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
}
}
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)
}
}
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)
