keyboardView.swift

A simple solution is to move view up with constant of keyboard height.



override func viewDidLoad() {
super.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(sender: NSNotification) {
let frame = (sender.userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue).CGRectValue()
self.view.frame.origin.y -= frame.height
}

func keyboardWillHide(sender: NSNotification) {
let frame = (sender.userInfo![UIKeyboardFrameEndUserInfoKey] as! NSValue).CGRectValue()
self.view.frame.origin.y += frame.height
}
