Ios Can'；t关闭iPhone 5和iPhone 5s的键盘

我试图以编程方式消除屏幕键盘，我的代码如下所示

override func viewDidLoad() {
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("keyboardWillShow:"), name:UIKeyboardWillShowNotification, object: nil);
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("keyboardWillHide:"), name:UIKeyboardWillHideNotification, object: nil);
}

func keyboardWillShow(notification: NSNotification) {
    var info = notification.userInfo!
    let keyboardFrame: CGRect = (info[UIKeyboardFrameEndUserInfoKey] as! NSValue).CGRectValue()
    UIView.animateWithDuration(0.1, animations: { () -> Void in
        self.Bottomspace.constant = keyboardFrame.size.height
    })
}

func keyboardWillHide(notification: NSNotification){
    self.Bottomspace.constant = 0
}

它适用于iPhone 6和iPad，但不适用于iPhone 5和iPhone 5s，有什么建议吗？

试试这个：

 // Dismiss Keyboard when user touch screen
    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        self.view.endEditing(true)
    }

//当用户触摸屏时关闭键盘
覆盖功能触摸开始（触摸：设置，withEvent事件：UIEvent？）{
self.view.endEditing（true）
}

让我知道它是否有效

将UITextFieldDelegate添加到类声明中：

class ViewController: UIViewController, UITextFieldDelegate

连接文本字段或以编程方式编写

@IBOutlet weak var userText: UITextField!

将视图控制器设置为视图中委托加载的文本字段：

override func viewDidLoad() {
super.viewDidLoad()
self.userText.delegate = self
}

添加此代理

func textFieldShouldReturn(userText: UITextField!) -> Bool {
yourtextfield.resignFirstResponder()
return true;
}

当你点击UITextField外部时？不，我点击键盘上的返回键。当你点击UITextField外部时？不，我点击键盘上的返回键
