I have the following (view) controller arrangement:

an uitableview –(embedded in)–> navigation controller –(embedded in)–> Tab bar controller –(modal segue to)–> button in a view (uiviewcontroller).

description of my problem:

The view with the button is the initial view of my app. Pressing this button leads to a tableview in a tab bar. At the beginning the table view is empty, but you can manually add information on the cells, like names. However, once you go back to initial view (with button) and press the button again, the previous entries in the table view are erased.Can somebody give a hint how to retain these entries with the given arrangement. Thank you very much in advance.

    You can use the singleton pattern. It will create a shared instance of your object, that you can access anywhere. You will then be able to write in it when the user adds a row in the table, and read it when you come to the tableView.

    Here is a bit of help : Singleton pattern

    EDIT : you can also use core data, but it may not be appropriate in your situation (plenty of docs on the web about that one)
