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)
}
其他回答
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*/
}
下面是关于如何在Xcode 6.1中使用Swift消除键盘的回答:
import UIKit
class ItemViewController: UIViewController, UITextFieldDelegate {
@IBOutlet var textFieldItemName: UITextField!
@IBOutlet var textFieldQt: UITextField!
@IBOutlet var textFieldMoreInfo: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
textFieldItemName.delegate = self
textFieldQt.delegate = self
textFieldMoreInfo.delegate = self
}
...
/**
* Called when 'return' key pressed. return NO to ignore.
*/
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
/**
* Called when the user click on the view (outside the UITextField).
*/
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
}
(此信息的来源)。
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
}
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
可以通过在AppDelegate的窗口属性中添加全局点击手势识别器来实现这一点。
这是一种非常全面的方法,对某些人来说可能不是理想的解决方案,但对我来说很有效。请让我知道这个解决方案是否有任何陷阱。
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Globally dismiss the keyboard when the "background" is tapped.
window?.addGestureRecognizer(
UITapGestureRecognizer(
target: window,
action: #selector(UIWindow.endEditing(_:))
)
)
return true
}
}
