Swinject 容器注册失败

Question

在尝试将某些协议绑定到各种 classes 时，我遇到了在协议中获取 nil 的奇怪行为。这是依赖注入器 class:

class DependencyInjector: NSObject {
    
    let container: Container
    
    override init() {
        container = Container()
        super.init()
        register()
    }
}

extension DependencyInjector {
    
    func register() {
        container.register(NetworkProtocols.self) { _ in ApiManager() }.inObjectScope(.container)
        container.register(ConnectivityManager.self) { r in
            let controller = ConnectivityManager()
            controller.network = r.resolve(NetworkProtocols.self)
            return controller
        }
        
        container.storyboardInitCompleted(ChooseCameraViewController.self) {r,c in
            c.network = r.resolve(NetworkProtocols.self)
        }
        
        container.storyboardInitCompleted(InstallationViewController.self) {r,c in
            c.network = r.resolve(NetworkProtocols.self)
        }
        
        container.storyboardInitCompleted(CameraSetupViewController.self) {r,c in
            c.network = r.resolve(NetworkProtocols.self)
        }
        
        container.storyboardInitCompleted(LoginViewController.self) { r,c in
            c.network = r.resolve(NetworkProtocols.self)
        }
    }
}

这是AppDelegate:

var dependencyInjector: DependencyInjector!

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.        
    dependencyInjector = DependencyInjector()
    
    let window = UIWindow(frame: UIScreen.main.bounds)
    self.window = window
    let bundle = Bundle(for: ViewController.self)
    let storyboard = SwinjectStoryboard.create(name: "Main", bundle: bundle, container: dependencyInjector.container)
    window.rootViewController = storyboard.instantiateInitialViewController()
    
    return true
}

在下面的 class 中，我在协议属性:

中得到 nil

class ConnectivityManager: NSObject {
    
    var network: NetworkProtocols!
    
    func connectHotSpot() {
        self.network.whoAmI(success: {
            print("api succses")
        }, failure: { (error) in
            print(error.localizedDescription)
        })
    }
}

网络变量始终是 nil，而在使用 storyboardInitCompleted 的其他 class 中，网络变量有效。

我做错了什么？

Answer 1

正如@JakubVano 所说，我必须获得 ConnectivityManager:

的一个实例

    container.register(ConnectivityManager.self) { r in
        let controller = ConnectivityManager()
        controller.network = r.resolve(NetworkProtocols.self)
        return controller
    }

   container.storyboardInitCompleted(ChooseCameraViewController.self) {r,c in
    c.connectivityManager = r.resolve(ConnectivityManager.self)!

    }
