[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)
}
}
斯威夫特3:
扩展选择器作为参数,能够做额外的东西在解散函数和cancelsTouchesInView,以防止扭曲与触摸的其他元素的视图。
extension UIViewController {
func hideKeyboardOnTap(_ selector: Selector) {
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: selector)
tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
}
用法:
override func viewDidLoad() {
super.viewDidLoad()
self.hideKeyboardOnTap(#selector(self.dismissKeyboard))
}
func dismissKeyboard() {
view.endEditing(true)
// do aditional stuff
}
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
}
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)
}
对于Swift3
在viewDidLoad中注册一个事件识别器
let tap = UITapGestureRecognizer(target: self, action: #selector(hideKeyBoard))
然后我们需要在相同的viewDidLoad中添加手势到视图中。
self.view.addGestureRecognizer(tap)
然后我们需要初始化注册的方法
func hideKeyBoard(sender: UITapGestureRecognizer? = nil){
view.endEditing(true)
}
