I tried with this process, If any thing wrong please correct me.

func applicationDidEnterBackground(_ application: UIApplication) {

        if((self.imgViewStaticImage) != nil)
        {
            self.imgViewStaticImage?.removeFromSuperview()
        }

        self.imgViewStaticImage = UIImageView(frame: (self.window?.bounds)!)
        self.imgViewStaticImage?.image = UIImage(named: "banner")
        self.window?.addSubview(self.imgViewStaticImage!)
    self.window?.bringSubview(toFront: self.imgViewStaticImage!)

    }

    func applicationWillEnterForeground(_ application: UIApplication) {

        if((self.imgViewStaticImage) != nil)
        {
            self.imgViewStaticImage?.removeFromSuperview()
        }

    }
