iphone tab bar controller and core data

Ok bit of a newbie type question.

I want to use Core Data, together with Tab and Navigation controllers.

In XCode if I create a Navigation Based Application I get the option to choose Core Data. Whereas If I create a Tab Bar Application I don't get the choice.

I understand that Tab Bars display view controllers so it kinda makes sense. However given that by default it sticks the basic Core Data code in the Application delegate I don't see why this isn't offered.

At the moment I'm creating the two projects and cutting and pasting between them.

Does this omission in XCode seem weird to you? Is it some sort of oversight?

Thanks, Matt

Solution

  • The templates are designed to be more 'pure', any combination of the templates is left as an exercise for the developer.

    They could do a CoreData + Tab and Nav Controller template, but to be fair they'd then have to do every other combination that might be 'reasonable'.

    Combining them yourself isn't that hard, and there's sample apps in the dev centre that show some of the combinations within a working application.
