you can also use [NSString getCharacters:(unichar array) range:(nsrange)]; you will get an easy to manipulate array.I needed it my self and found it on this link

NSString * fooString = @"FOOSTRING";
NSMutableArray *list = [NSMutableArray array];
for (int i=0; i<fooString.length; i++) {
    [list addObject:[fooString substringWithRange:NSMakeRange(i, 1)]];
}
NSLog(@"%@", list);

NSLog output:

(
                                                  F,
                                                  O,
                                                  O,
                                                  S,
                                                  T,
                                                  R,
                                                  I,
                                                  N,
                                                  G
                                                  )

How about

[fooString cStringUsingEncoding: NSUTF8StringEncoding];
