  2. If you XCode doesn't recognize NSFontAttributeName, you are probably not using SDK 6.0

  6. NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:@"Iamthebest"];
    UIFont *font=[UIFont fontWithName:@"Helvetica-Bold" size:25.0f];
    [attString addAttribute:NSFontAttributeName value:font range:NSMakeRange(0,1)];


    mLbl.attributedText=attString;

    This will make Character I as BOLD

  12. I need to still get it working w/ everything NSAttributedString has to offer, but I think fontName, fontSize and color cover the bulk of it. Expect lots of updates soon :)

    I can help you get started with this if you need. Also looking for feedback, so if it makes your life easier, I'd say mission accomplished.
