How to the fix the problem in UIView animation?

Question

Textfield animation view moves upward 240 then the keyboard and view between there is a black background. I need to fix it.

The program I tried:

func textFieldDidBeginEditing(_ textField: UITextField) {
    animateViewMoving(up: true, moveValue: 240)
}

func textFieldDidEndEditing(_ textField: UITextField) {
    animateViewMoving(up: false, moveValue: 240)
}

func animateViewMoving (up:Bool, moveValue :CGFloat){
    let movementDuration:TimeInterval = 0.3
    let movement:CGFloat = ( up ? -moveValue : moveValue)
    UIView.beginAnimations( "animateView", context: nil)
    UIView.setAnimationBeginsFromCurrentState(true)
    UIView.setAnimationDuration(movementDuration )
    self.view.frame = self.view.frame.offsetBy(dx: 0, dy: movement)
    UIView.commitAnimations()
    self.view.backgroundColor = UIColor.red
}

func textFieldDidBeginEditing(_ textField: UITextField) {
    animateViewMoving(up: true, moveValue: 240)
}

func textFieldDidEndEditing(_ textField: UITextField) {
    animateViewMoving(up: false, moveValue: 240)
}

I expect the black background colour to be replaced with the white background but it's not working. I tried with view background colour the actual colour I need white colour.

Make Outlet of view which you want to move up and set outlet instead of UIVIEW. and try — Dhaval Umraliya, Apr 18 '19 at 04:12
Instead of hard coded 240, get the height of the keyboard and move view to that value. [This](https://stackoverflow.com/questions/31774006/how-to-get-height-of-keyboard) might help!. — Kamran, Apr 18 '19 at 04:21

I think this is the window color. You can try changing the color by UIApplication.shared.keyWindow?.backgroundColor = UIColor.white

@kranthibabu please upvote if the answer was correct – ayon.gupta Apr 18 '19 at 05:32
This is hack at its best :D. Will fail if the UIView background color is anything but white. Better option still would be to use keyboard height and move accordingly as mentioned by @Kamran in the comments section of the question – iOSer Apr 18 '19 at 05:34
