Answer 1

Below is a solution based on Jesse Rusak's suggestion, however even the UITextInputTokenizer seems to be unable to properly parse the text, unless of course the error is on my part :)

+(void)parse:(UITextField *)textfield {
    id tokenizer = [textfield tokenizer];
    UITextPosition *pos = textfield.beginningOfDocument;

    while (true) {
        UITextRange *range = [tokenizer rangeEnclosingPosition:pos withGranularity:UITextGranularityCharacter inDirection:UITextStorageDirectionForward];
        NSString *oneCharacter = [textfield textInRange:range];

        NSLog( @"%@", oneCharacter );

        pos = [textfield positionFromPosition:pos offset:-1];

        if (pos == nil) break;
    }
}
