macOS Sorting....help! [SOLVED]

[LostSoul80]

Hi all,
how can i sort an NSArray containing NSDictionaries, wich contain NSNumber objects as a key, ascending by the keys?

Thanks

I would look into:

I just re-read what you said... and it seems like you want to sort by the keys not the values, which seems strange. Can you clarify what the keys look like?

Create a custom sort selector to do the comparison and use -[NSArray sortUsingSelector:]. It's probably not the fastest way to do it, but definitely the easiest.

Hi, thanks for reply.
I was already using NSSortDescriptors, but such in a wrong way - i was having troubles because i hadn't realized NSNumber has a compare: method... so i was trying to create a custom comparison method, wich had had to convert the nsnumber into an nsstring to finally do the comparison, by calling -[NSString compare:string options:NSNumericSearch]. This makes me laugh. Sorry for this topic.
