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?

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)
}

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)
}
}
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)
}
}
这里有一个简单的方法:
let endEditingTapGesture = UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing(_:)))
endEditingTapGesture.cancelsTouchesInView = false
view.addGestureRecognizer(endEditingTapGesture)
我在uisearchbar上锻炼。看到我的。
import UIKit
class BidderPage: UIViewController,UISearchBarDelegate,UITableViewDataSource {
let recognizer = UITapGestureRecognizer()
// Set recogniser as public in case of tableview and didselectindexpath.
func searchBarTextDidBeginEditing(searchBar: UISearchBar)
{
recognizer.addTarget(self, action: "handleTap:")
view.addGestureRecognizer(recognizer)
}
func handleTap(recognizer: UITapGestureRecognizer) {
biddersearchbar .resignFirstResponder()
}
func searchBarTextDidEndEditing(searchBar: UISearchBar)
{
view .removeGestureRecognizer(recognizer)
}
override func viewDidLoad() {
super.viewDidLoad()
self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tap)))
}
func tap(sender: UITapGestureRecognizer){
print("tapped")
view.endEditing(true)
}
试试这个,很管用
