Swinject, injecting an object in a subclass of UICollectionView Or UIView

[chandrapal199]

I have created a subclass of UICollectionView and assigned this custom class into storyboard's collection view. I have to inject a shared object in that custom class.

// ViewController
class BZConnectSocialAcccountViewC: BZSignupWizardBase {

    @IBOutlet weak var collectionView: BZConnectSocialListView!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func viewDidLoad() {
        super.viewDidLoad()

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

// Sub Class
class BZConnectSocialListView: UICollectionView {

    var connectSocialAccountViewModeling: BZConnectSocialAccountViewModeling?
}

// View Model
protocol BZConnectSocialAccountViewModeling {
}

class BZConnectSocialAccountVM: BZConnectSocialAccountViewModeling {

 private var objApiManager: APIManagerModeling?
    init(_ apiManager: APIManagerModeling) {

        self.objApiManager = apiManager
    }
}

// API Manager

protocol APIManagerModeling {
}
class APIManager: SessionManager, APIManagerModeling {
}

// Injection

container.register(APIManagerModeling.self) { _ in
            APIManager()
        }.inObjectScope(.container)

container.register(BZConnectSocialAccountViewModeling.self) { r in
            BZConnectSocialAccountVM(r.resolve(APIManagerModeling.self)!)
        }

container.register(BZConnectSocialAcccountViewC.self) { r in

            return self.viewControllerFor(storyboard: self.storyboardSettings(className: BZConnectSocialAcccountViewC.self), identifier: BZConnectSocialAcccountViewC.className) as! BZConnectSocialAcccountViewC

            }.initCompleted { r, c in

                c.collectionView.connectSocialAccountViewModeling = r.resolve(BZConnectSocialAccountViewModeling.self)

        }

c.collectionView in getting nil

Hi @chandrapal199 this looks more like a problem with your storyboard setup than Swinject configuration.

It is hard to say without seeing your storyboard, although couple of things that come to mind:

• is collectionView part of a view hierarchy of BZConnectSocialAcccountViewC?
• is @IBOutlet weak var collectionView properly linked in storyboard?
• have you tried making @IBOutlet weak var collectionView not-weak?

It is properly connected in storyboard. Please check in screen shot.

Can you please give me some idea to inject a dependency on sub-class.

@chandrapal199, do you still have the issue? Or did you resolve the issue yourself?

I took another way to handle this problem.
