Hook for Objective C class' category initialization?

[Eimantas Vaičiūnas]

Dear List,

I'm creating a category for enumerable types of cocoa frameworks (like
NSArray, NSSet and NSDictionary). I was wondering if there are any
methods that are called when category is being "included" for the
object (loaded into memory?). Something like + (void)initialize?

All the best,

+load is called when categories are loaded into memory, but there's no
+initialize when they're first used I'm afraid.

Thanks for such a quick response, Jim!

Note that +load is special. Unlike any other method, a +load in a category will not override +load in the original class. Both will get called.
