Handling the keyboard notifications

// MARK: - View Life Cycle
overridefunc viewWillAppear(animated:Bool){
super.viewWillAppear(animated)EventBox.onMainThread(self, name: UIKeyboardWillShowNotification, handler:{ n inself.keyboardWillChangeFrame(n, showsKeyboard:true)})EventBox.onMainThread(self, name: UIKeyboardWillHideNotification, handler:{ n inself.keyboardWillChangeFrame(n, showsKeyboard:false)})}overridefunc viewDidDisappear(animated:Bool){
super.viewDidDisappear(animated)EventBox.off(self)}
// MARK: - Keyboard Event Notifications
func keyboardWillChangeFrame(notification:NSNotification, showsKeyboard:Bool){letuserInfo= notification.userInfo!
letanimationDuration=(userInfo[UIKeyboardAnimationDurationUserInfoKey]asNSNumber).doubleValue
letkeyboardScreenEndFrame=(userInfo[UIKeyboardFrameEndUserInfoKey]asNSValue).CGRectValue()if showsKeyboard {letorientation:UIInterfaceOrientation=UIApplication.sharedApplication().statusBarOrientation
if(orientation.isLandscape){
containerViewButtomConstraint.constant = keyboardScreenEndFrame.size.width
}else{
containerViewButtomConstraint.constant = keyboardScreenEndFrame.size.height
}}else{
containerViewButtomConstraint.constant =0}self.view.setNeedsUpdateConstraints()UIView.animateWithDuration(animationDuration, delay:0, options:.BeginFromCurrentState, animations:{self.containerView.alpha = showsKeyboard ?1:0self.view.layoutIfNeeded()}, completion:{ finished inif !showsKeyboard {self.view.hidden =true}})}
