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
为了扩展Esqarrouth的答案,我总是使用以下方法来解除键盘,特别是如果我正在解除键盘的类没有view属性和/或不是UIView的子类。
UIApplication.shared.keyWindow?.endEditing(true)
并且,为了方便起见,下面是uiapplication类的扩展:
extension UIApplication {
/// Dismisses the keyboard from the key window of the
/// shared application instance.
///
/// - Parameters:
/// - force: specify `true` to force first responder to resign.
open class func endEditing(_ force: Bool = false) {
shared.endEditing(force)
}
/// Dismisses the keyboard from the key window of this
/// application instance.
///
/// - Parameters:
/// - force: specify `true` to force first responder to resign.
open func endEditing(_ force: Bool = false) {
keyWindow?.endEditing(force)
}
}

斯威夫特3
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view.endEditing(true)
}
你可以打电话
resignFirstResponder()
在UIResponder的任何实例上,例如UITextField。如果你在当前导致键盘显示的视图上调用它,那么键盘将会消失。
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 ()
//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
}
}
添加这个扩展到你的ViewController:
extension UIViewController {
// Ends editing view when touches to view
open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
self.view.endEditing(true)
}
}
