swift - 如何在没有 AppDelegate Swift 的情况下创建 CosmicMind CardTableView

Question

我需要通过从另一个视图调用它来创建这个视图，我需要能够在没有 appdelegate 的情况下创建视图。我需要这方面的帮助。谢谢

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

SampleData.createSampleData()

let graph = Graph()
let search = Search<Entity>(graph: graph).for(types: "Category")

var viewControllers = [PostsViewController]()

for category in search.sync() {
    if let name = category["name"] as? String {
        viewControllers.append(PostsViewController(category: name))
    }
}

let pageTabBarController = AppPageTabBarController(viewControllers: viewControllers)
let toolbarController = AppToolbarController(rootViewController: pageTabBarController)
let menuController = AppMenuController(rootViewController: toolbarController)
let leftViewController = LeftViewController()

let navigationDrawerController = NavigationDrawerController(rootViewController: menuController,
                                                            leftViewController: leftViewController
                                                            )

window = UIWindow(frame: Screen.bounds)
window!.rootViewController = navigationDrawerController
window!.makeKeyAndVisible()

return true 

}

**这是我的代码，一直崩溃**

导入 UIKit 导入 材质 导入 Graph

类视图控制器：PageTabBarController {

var window: UIWindow?

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}


open override func prepare() {
    super.prepare()
    SampleData.createSampleData()

    let graph = Graph()
    let search = Search<Entity>(graph: graph).for(types: "Category")

    var viewControllers = [PostsViewController]()

    for category in search.sync() {
        if let name = category["name"] as? String {
            viewControllers.append(PostsViewController(category: name))
        }
    }

    let pageTabBarController = AppPageTabBarController(viewControllers: viewControllers)
    let toolbarController = AppToolbarController(rootViewController: pageTabBarController)
    let menuController = AppMenuController(rootViewController: toolbarController)
    let leftViewController = LeftViewController()

    let navigationDrawerController = NavigationDrawerController(rootViewController: menuController,
                                                                leftViewController: leftViewController
    )

    window = UIWindow(frame: Screen.bounds)
    window!.rootViewController = navigationDrawerController
    window!.makeKeyAndVisible()
}

} 扩展 ViewController: PageTabBarControllerDelegate { func pageTabBarController(_ pageTabBarController: PageTabBarController, didTransitionTo viewController: UIViewController) {

}

}
