How to explode an NSString into single NSString characters

Say you had an NSString, and you’re interested in each single character. You’d think there’s a method for it, such as getCharactersInRange. Turns out that’s not really helpful, because it delivers unichar characters rather than NSStrings.

To extract single characters as NSStrings, we can use the substringWithRange method like so:

NSString *phrase = @"Complex stuff.";

// split NSString into its characters
for (int i=0; i<phrase.length; i++) {
    NSRange range = NSMakeRange(i, 1);
    NSString *character = [phrase substringWithRange:range];
    NSLog(@"Character is %@", character);
}
