    Create a font larger than you would ever want (48 points is probably good). Then use this:

    CGFloat maxFontSize;
[string sizeWithFont:font minFontSize:0 actualFontSize:&maxFontSize forWidth:maxWidth lineBreakMode: UILineBreakModeClip];

    maxFontSize will hold the largest size less than 48 and greater than 0 that will fit within maxWidth.
