Solution

  • In Like_btn_Action() function, you:

    • create an instance of LikeViewController
    • add it as a child view controller
    • add its view to your view
    • set that view's background color

    and then the function exits. At this point, you no longer have a reference to your instance of LikeViewController ... likeVC has gone out of scope.

    You need to use a class-level var to maintain the reference to the loaded child view controller, along these lines:

    var likeVC: LikeViewController?
@IBAction func Like_btn_Action(_ sender: Any) {
    likeVC = self.storyboard?.instantiateViewController( etc ...)
}

    Then, when you want to remove the view you added, you can "get to it" via:

    likeVC.view.removeFromSuperview()

    for example.
