While working on an iPhone app, I had occasion to create some ‘utility code’ – functions that were used by several view controllers, but that didn’t really belong to any one in particular. It wasn’t clear to me where this code should live; assigning it to any one VC was a non-starter, and, since I was using pure plist data structures (NSDictionaries, NSArrays, etc.) as my models, it didn’t seem natural to add the code to them, either.
In the end I decided to stick the code into the Application Delegate, but I felt guilty about it.
