How to get Entity Name in coredata

Question

I have first project that dealing with coreData. I followed this tutorial. Everything was fine until I created new project with new core data models that has same fields and same structure to have deeper understand. However, I couldn't figure out where the variable self.entityName in class SDDateTableViewController.m got assigned value. Because the variable self.entityName in my new project is getting nil in method -(void)loadRecordsFromCoreData in SDDateTableViewController.m class.

Note: I did try copy every single line of code to my project, but the variable self.entityName is still nil

Please help me explain this issue.

Answer 1

It is define in the Storyboard on the SDDateTableViewController scene on "User defined runtime attributes".
