IOS: leave space from a nsstring and manage commas
===

I have this nsstring 

    Manhattan, New York, Stati Uniti

I want leave all space and I can use replacestring with @"", it's ok for me;
my very problem is that I want put all element separate by commas in an array, is it possible?

for example the array'll be array = [Manhattan] [New York] [Stati Uniti]

thanks
