I saw an example in The iPhone Developer’s Cookbook that extends the UIDevice class using categories.
@interface UIDevice (Reachability)
// some methods
@end
Typically classes are nouns and methods are verbs. From my point of view categories are similar to subclasses, so I would name the category a noun such as NetworkedUIDevice. How should the name of the category be determined?
I don’t think a strict naming convention is established. Personally, I would go with something like
@interface UIDevice (ReachabilityAdditions).More importantly, you should add a custom prefix to your category methods to avoid namespace conflicts. And this prefix should probably be included in the category name as well.
