objective c - NSString get -characters -

i want characters of nsstring. this:

but nsstring won't respond -characters. how characters of nsstring?

thanks, elijah

you can use function:

for(int =0 ;i<[mystring length]; i++) {   char character = [mystring characteratindex:i]; } 

or

nsstring *str = @"astring"; const char *cstring = [str utf8string];
