importing AppDelegate

Question

Often times I initialize my model class variables in my AppDelegate so they can be used by different ViewControllers without passing their instance across class files. Howe

Answer 1

You should seriously avoid importing the AppDelegate everywhere and you should feel like you are doing something wrong each time you do it (+1 for that). You are essentially creating a Big Ball of Mud and should reconsider your design. If for example you are using CoreData for your models consider a framework such as Magical Panda Active Record to retrieve data. I work on an enterprise application and the AppDelegate.h is only include in AppDelegate.m.
