While trying to bind some protocols to various classes I have encountered a strange behaviour of getting nil
in the protocols.
This is the dependency injector 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)
}
}
}
This is the 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
}
In the class below I get nil
in the protocol property:
class ConnectivityManager: NSObject {
var network: NetworkProtocols!
func connectHotSpot() {
self.network.whoAmI(success: {
print("api succses")
}, failure: { (error) in
print(error.localizedDescription)
})
}
}
The network var is always nil
while in the other classes that use storyboardInitCompleted
the network var works.
What am I doing wrong?
As @JakubVano said I had to obtain an instance of ConnectivityManager
:
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)!
}
