Coming from other object based languages I'm aware that each language can have it's own idioms for common tasks. In particular coming from doing a lot of python, I'm finding myself wanting to do a few things with NSArrays that I would do quite easily with python lists.
Can anybody suggest a good way to: 1) Given an ordered set of objects, create a new non-mutable ordered set, with all the duplicates removed? 2) Given an ordered set of objects, create a new non-mutable ordered set, with each entry being the output of a method applied to each entry of the original array (e.g. Python map())? I can easily write 'for each' loops that do these and create mutable arrays, and then return non-mutable copies, but I half expect that these are common patterns, and there might be a nice, concise, way of writing them. Are there any ObjC shortcuts when doing things like this? Am I best writing a category on top of NSArray the encompass these (and other) patterns? I'd like to retain ordering, so using NSSet for (1) seems counter productive. Thanks P.S. Alternatively, Is there a site like http://aspn.activestate.com/ASPN/Cookbook/Python/ for Objective C? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
