Are there any Objective-C frameworks like Cocoa which provide Arrays, Dictionaries, Strings, etc

Before I start to write my own, are there any Objective-C frameworks or libraries that provide Arrays, Dictionaies and Strings? I am writing for windows so the开发者_StackOverflow中文版re is no Cocoa, there are ports. But I am only writing a small command line application so I don't really want to use Cocoa because it is quite large. I have looked around and all I can find is Cocoa.

Foundation framework provides standard containers for you (each of them can hold objective-c objects only):

• NSArray and NSMutableArray
• NSString and NSMutableString
• NSDictionary and NSMutableDictionary
• NSSet and NSMutableSet
