- (void)textFieldDidBeginEditing:(UITextField *)textField{

    [self animateTextField:textField up:YES];

}

- (void)textFieldDidEndEditing:(UITextField *)textField{

    [self animateTextField:textField up:NO];}

-(void)animateTextField:(UITextField*)textField up:(BOOL)up

{

    int movementDistance = -100; // tweak as needed

    float movementDuration = 0.3f; // tweak as needed

    int movement = (up ? movementDistance : -movementDistance);

    [UIView beginAnimations: @"animateTextField" context: nil];

    [UIView setAnimationBeginsFromCurrentState: YES];

    [UIView setAnimationDuration: movementDuration];

    self.view.frame = CGRectOffset(self.view.frame, 0, movement);

    [UIView commitAnimations];
