iOS App Launch Image After a Kill

Question

When I kill my iPhone app and relaunch it I have an image of the app\'s previous state instead of the launch image. How can I force iOS to always show the launch image?

Answer 1

Swift 4.2

func applicationDidEnterBackground(_ application: UIApplication) {

        let imageView = UIImageView(frame: self.window!.bounds)
        imageView.tag = 25
        imageView.image = UIImage(named: )
        UIApplication.shared.keyWindow?.subviews.last?.addSubview(imageView)
}

func applicationWillEnterForeground(_ application: UIApplication) {

        if let imageView : UIImageView = UIApplication.shared.keyWindow?.subviews.last?.viewWithTag(25) as? UIImageView {
            imageView.removeFromSuperview()
        }

}
