ios - Swinject 注册 UIViewController 最佳实践

Question

此时，在我的项目中，我使用 Swinject(DI 容器)。

如果我有以下层次结构，我想知道如何注册 ViewController:

class RateAnswersBaseVC: UIViewController { }
class RateAnswersDoctorVC: RateAnswersBaseVC { }
class RateAnswersQualityVC: RateAnswersBaseVC { }

如何将自己的权利注册和使用？在我使用第一个选项的项目中，此时我有两个选项，但感觉我们应该使用第二个:)

// ------- 1 --------
container.register(RateAnswersDoctorVC.self) { r in
    let vc: RateAnswersDoctorVC = RateAnswersDoctorVC()
    self.configureBasicFields(with: vc, container: container, resolver: r)
    return vc
}

container.register(RateAnswersQualityVC.self) { r in
    let vc: RateAnswersQualityVC = RateAnswersQualityVC()
    self.configureBasicFields(with: vc, container: container, resolver: r)
    return vc
}

// ------- 2 --------
container.register(RateAnswersBaseVC.self, name: "doctor") { r in
    let vc: RateAnswersDoctorVC = RateAnswersDoctorVC()
    self.configureBasicFields(with: vc, container: container, resolver: r)
    return vc
}

container.register(RateAnswersBaseVC.self, name: "quality") { r in
    let vc: RateAnswersQualityVC = RateAnswersQualityVC()
    self.configureBasicFields(with: vc, container: container, resolver: r)
    return vc
}

如果您解释为什么使用其中一种方法，我将很高兴。

上次我在项目中使用 MVVM 模式。因此，我将应用程序的业务逻辑拆分为模块 - 提供某些功能或业务逻辑的完整代码部分(例如在应用程序中登录、全屏播放视频等)。我为每个模块创建一个 Assembly 对象来配置模块中的依赖项。

class PasswordAssembly: Assembly {
     func assemble(container: Container) {
        container.register(PasswordViewInterface.self) { (_: Resolver) in
            PasswordViewController(nibName: "PasswordViewController", bundle: nil)
        }
        .initCompleted { resolver, view in
            var view = view as PasswordViewInterface
            view.viewModel = resolver.resolve(PasswordViewModelInterface.self)
            view.router = resolver.resolve(PasswordRouterInterface.self)
        }

        container.register(PasswordViewModelInterface.self) { (resolver: Resolver) in
            return PasswordViewModel(coreModel: resolver.resolve(CoreViewModelInterface.self)!)
        }

        container.register(PasswordRouterInterface.self) { _ in
            return PasswordRouter()
        }
        .initCompleted { (resolver, router) in
            var router = router as PasswordRouterInterface
            router.view = resolver.resolve(PasswordViewInterface.self)
            router.resolver = container
        }
    }
}

我还注入(inject)路由器 Resolver (Container) 对象来制作 Router 构建层次结构

protocol PasswordRouterInterface {
    var view: PasswordViewInterface! { get set }
    var resolver: Resolver! { get set }

    func presentFilesListView()
    func presentContentView()
}

class PasswordRouter: PasswordRouterInterface {
    var view: PasswordViewInterface!
    var resolver: Resolver!

    func presentFilesListView() {
        if let listViewController = resolver.resolve(FilesListViewInterface.self)?.getViewController() {
            let navigationController = UINavigationController(rootViewController: listViewController)
            view.getViewController().present(navigationController, animated: true) {

            }
        }
    }

    func presentContentView() {

    }
}
