使用此代码

    self.view.endEditing(true)
}
func textFieldDidBeginEditing(textField: UITextField) {

    textField.keyboardType = UIKeyboardType.EmailAddress
    self.animateViewMoving(true, moveValue: 50)
}
func textFieldDidEndEditing(textField: UITextField) {
    self.animateViewMoving(false, moveValue: 50)

}
func textFieldShouldReturn(textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    return true
}
func animateViewMoving (up:Bool, moveValue :CGFloat){
    var movementDuration:NSTimeInterval = 0.3
    var movement:CGFloat = ( up ? -moveValue : moveValue)
    UIView.beginAnimations( "animateView", context: nil)
    UIView.setAnimationBeginsFromCurrentState(true)
    UIView.setAnimationDuration(movementDuration )
    self.view.frame = CGRectOffset(self.view.frame, 0,  movement)
    UIView.commitAnimations()
}
