Cocoa read string character by character?

Question

I am aiming to create an app which receives an NSString, like "A12EE345", then reads the string character by character, perhaps in a for loop, and performs an action on each character. A bit like reading a file line by line, but reading a string character by character?

Thanks in advance

you should read apple documentation. – Parag Bafna Jan 28 '12 at 16:27 — Parag Bafna, Jan 28 '12 at 16:27

NSString *inputString = @"A12EE345";
for (NSUInteger i = 0; i < inputString.length; i++) {
    NSString *character = [inputString substringWithRange:NSMakeRange(i, 1)];
    NSLog(@"Character: %@", character);
}

Or use `characterAtIndex:`, the `unichar` type, and the `%C` formatting sequence. – Peter Hosey Jan 28 '12 at 22:30
