2,049 Pointsapplication logout functionality in iOS 9 using objective C
I'm designing an app with logout functionality where the logout button is embedded in UITableViewCell and this logout button is presented as a popover using UIPopOverPresentationControllerDelegate. Its like a 3tier hierarchy first login screen (rootVIewController) will be shown then it will be navigated to UITabBarController using navigation controller with three tabs like this (navigationController->rootVIewController->navigationController->TabBarController). This tab bar controller consists of logout button which is represented as UIBarButtonItem. Entire navigation is done using storyboards. My question is how to get back to login screen (rootViewController) on clicking this logout button (presented as popover). Any help is much appreciated and sorry for my english. could have provided the screen shot of my storyboard for clear understanding but there isn't any option here
