问题 In VIPER, unlike the MVC, the role and place not so clearly defined for NSFetchedResultsController.

问题 I am writing an application which has a TabBar based navigation. I am adopting the VIPER architecture but I am really confused with the topic of how a UITabBarController's tab changing should be implemented. 回答1: This might be late, but it might be helpful for others. My use case was to implement the tabBarController after the login screen. There can be many ways we can do it in VIPER but how I did it is as follows: Allocated TabBar manually, without using storyboards. Create a new WireFrame
