        }

        setTitleTextAttributes(attributes, forState: .Normal)
    }
    
    override func intrinsicContentSize() -> CGSize {
        var size = super.intrinsicContentSize()
        
        if let fontName = titleFontName, let font = UIFont(name: fontName, size: titleFontSize) {
            size.height = floor(font.lineHeight + 2 * segmentPadding.height)
        }
        else {
            size.height += segmentPadding.height * 2
        }
        
        size.width  += segmentPadding.width * CGFloat(numberOfSegments + 1)
        
        return size
    }
    
}

Line 56 should that be instead : ?

        size.width  += 2*segmentPadding.width * CGFloat(numberOfSegments)
