I am using UINavigation controller as root view controller to navigate my app.After login/sign-up my app launches UITab-Bar-Controller which has static tabs(UI-View-Controllers),which is created/linked in storyboard.
Here I am getting nil in presenter obj in my tab bar (view-controller) class, because may be i only pushed UI-Tab-Bar-Controller not viewController in UINavigationController and when I try to call presenter. Also I have no clue how do I manage tab bar internal class while changing tabs.
