This code worked for me on iOS 6:

    - (void)tappedTextView:(UITapGestureRecognizer *)recognizer {
        UITextView *textView = (UITextView *)recognizer.view;
        CGPoint location = [recognizer locationInView:textView];
        UITextPosition *tapPosition = [textView closestPositionToPoint:location];
        UITextRange *textRange = [textView.tokenizer rangeEnclosingPosition:tapPosition withGranularity:UITextGranularityCharacter inDirection:UITextLayoutDirectionRight];        
        NSString *character = [textView textInRange:textRange];
        NSLog(@"%@", character);
    }
