Texture(AsyncDisplayKit) image flash

I have a viewcontroller inheriting ASDKViewController, the background is set to a picture, when I switch tabs, the picture flashes，how can i fix it?

enter image description here

in SceneDelegate:

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = (scene as? UIWindowScene) else { return }
    

    
    window = UIWindow(frame: UIScreen.main.bounds)
    window?.windowScene = windowScene
    
    let tab = UITabBarController()
    let vc1 = ViewController()
    vc1.title = "vc1"
    let vc2 = TestViewController()
    vc2.title = "vc2"
    tab.viewControllers = [vc1,vc2]
    window?.rootViewController = tab
    window?.makeKeyAndVisible()
    
}

in ViewController:

class ViewController: ASDKViewController<ASDisplayNode> {

override init() {
    let bgImageView = ASImageNode()
    bgImageView.image = UIImage(named: "backBg")
    bgImageView.isUserInteractionEnabled = true
    super.init(node: bgImageView)
}

required init?(coder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

override func viewDidLoad() {
    super.viewDidLoad()
}
Solution

  • Ok, so the solution will be:

        let bgImageView = ASImageNode()
    bgImageView.displaysAsynchronously = false
