Question

I have a NSArray with some “towns” in it (get these towns from a json database), but there are some towns 2 or 3 times in the array and I have to delete these towns.

How can I solve this problem? with a for-loop or a spezific function in x-code?

please help!

Answer 1

one line solution, you need to add autorelease for non-ARC project

NSArray *array = // your array
NSArray filteredArray = [[[NSOrderedSet alloc] initWithArray:array] array];
