create a 10.99 (with small "99") string that can be placed in a label.

SmallCent.swift

func formatPriceString(costString:String,costLabel:UILabel) {
  if let range = costString.rangeOfString(".") {
				let attributeString: NSMutableAttributedString =  NSMutableAttributedString(string: costString)
				let pos = costString.startIndex.distanceTo(range.startIndex)
				let centsRange = NSMakeRange(pos, 3)
				
				let smallFont = UIFont(name: costLabel.font.fontName,size:10)
				let offsetAmount = self.costLabel.font.capHeight - smallFont!.capHeight
				attributeString.addAttribute(NSFontAttributeName, value: smallFont!, range: centsRange)
				attributeString.addAttribute(NSBaselineOffsetAttributeName, value: offsetAmount, range: centsRange)
				self.costLabel.attributedText = attributeString
			}
