ios - 无法关闭 iPhone 5 和 iPhone 5s 的键盘

Question

我正在尝试以编程方式关闭屏幕键盘，我的代码如下

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？

Answer 1

试试这个:

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

让我知道它是否有效!
