Question

I have something like:

NSString *str = "hello this is 123.";

I want it to be placed into a char array, so I can read it character by character.

So it would be like:

charArray[0] = 'h'
charArray[1] = 'e'
charArray[2] = 'l'

and so on..

How can I convert a string to a char array and how can I read each cell of the char array?

Answer 1

NSString *s = @"hello this is 123.";
const char *c = [s UTF8String];

You could also use -[NSString cStringUsingEncoding:] if your string is encoded with something other than UTF-8.
