无法为iPhone 5和iPhone5s

关闭键盘

我试图编程方式关闭屏幕上的键盘和我有我的代码如下无法为iPhone 5和iPhone5s

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 
}

它做工精细的iPhone 6和iPad，而不是iPhone 5和iPhone 5s，有什么建议吗？

就在您点击UITextField外部时？ – senty

诺普，我做键盘上的返回键 –

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，如果它的工作原理！

啊，它的工作原理！非常感谢你！ –

添加UITextFieldDelegate到类声明：

class ViewController: UIViewController, UITextFieldDelegate

连接文本框或者编程写

@IBOutlet weak var userText: UITextField!

设置您的视图控制器在视图中的文本字段代表做负载：

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

添加此代表

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