Equivalent of C++ STL container "pair<T1, T2>" in Objective-C?

Question

I'm new to Objective-C, so please don't judge me too much. I was wondering: Is there an equivalent of the C++ STL pair container I can use in Objective-C?

I want to build an array that contains an NSInteger associated to an NSBool. I know I could use an array with each entry being a NSDictionary with a single key-value but I find it to be a little overkill.

Any ideas?

Thanks.
