How to join NSArray elements into an NSString?

Question

Given an NSArray of NSStrings, is there a quick way to join them together into a single NSString (with a Separator)?

Answer 1

NSArray * stuff = /* ... */;
NSString * combinedStuff = [stuff componentsJoinedByString:@"separator"];

This is the inverse of -[NSString componentsSeparatedByString:].

Answer 2

-componentsJoinedByString: on NSArray should do the trick.
