Do I need to import the AppDelegate_Phone.h file?

Do I need to import the AppDelegate_Phone.h file (which in turn 开发者_如何学Cimports AppDelegate_Shared.h)?

I am trying to use Core Data. The AppDelegate_Shared.h already has it set up. If I want to read information into a UITableView from Core Data, must I import my delegate file explicitly?

I think so, but I also don't see a down side to doing it anyway.
