当广告加载时按钮消失

Question

我用一些按钮编写了一个应用程序。其中一个按下按钮显示插页式广告。当我关闭广告时，视图上的所有按钮消失。我该如何解决这个问题？

Answer 1

这就是所谓的每次视图出现在屏幕上，在加载时不会。在ViewDidLoad方法内移动该代码

//When view is loaded 
override func viewDidAppear(_ animated: Bool) { 
    super.viewDidAppear(animated) 
    BT6.isHidden = true 
    BT5.isHidden = true 
    BT4.isHidden = true 
    BT3.isHidden = true 
    BT2.isHidden = true 
    //Hiding all but one button when the view controller loads 
}
