Hi Rick,

It sounds to me like one way of looking at your data structures is as a NSDictionary with the first array as keys and the second as objects (values).
If so, you could then sort the keys using - (NSArray *)keysSortedByValueUsingComparator:(NSComparator)cmptr , or one of the other sorting methods, and use the returned array to access the objects in turn. If the array-contaner is important for your code add the "sorted" objects to an array.

NSArray, of course, also has a set of sorting methods, you could leverage to co-sort the strings in place.

Any advice on what the best way to approach this is would be great since I don't have a lot of experience in sorting like this.  Thanks!
