纹理(AsyncDisplayKit)图像闪存

Question

我有一个继承了ASDKViewController的视图控制器，背景设置为图片，当我切换选项卡时，图片闪烁，我如何修复它？

​

在SceneDelegate中

    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()
    
}

在ViewController中

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()
}

好的，那么解决方案是：

    let bgImageView = ASImageNode()
    bgImageView.displaysAsynchronously = false
