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
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*/
}
其他回答
如果你有其他视图也应该接收触摸,你必须设置 cancelsTouchesInView = false
是这样的:
let elsewhereTap = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard))
elsewhereTap.cancelsTouchesInView = false
self.view.addGestureRecognizer(elsewhereTap)
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")
}
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)
}
}
斯威夫特3: 关闭键盘的最简单方法:
//Dismiss keyboard method
func keyboardDismiss() {
textField.resignFirstResponder()
}
//ADD Gesture Recignizer to Dismiss keyboard then view tapped
@IBAction func viewTapped(_ sender: AnyObject) {
keyboardDismiss()
}
//Dismiss keyboard using Return Key (Done) Button
//Do not forgot to add protocol UITextFieldDelegate
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
keyboardDismiss()
return true
}
你可以使用swift
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
view.endEditing(true)
}
