Simply way to set background color for a view using RGB color in 0-255

gistfile1.swift

private func setBackgroundColor(redColor: Int, greenColor: Int, blueColor: Int) -> Bool{
        // colors should be from 0 to 255, like you get when picking colors in Photoshop
        if redColor < 0 || greenColor < 0 || blueColor < 0 {
            println("At least one color value not in range. Must be at least 0")
            return false
        }
        if redColor > 255 || greenColor > 255 || blueColor > 255 {
            println("At least one color value not in range. Must be at less than 255")
            return false
        }
        
        self.view.backgroundColor = UIColor(
            red: CGFloat( Float(redColor+1) / Float(256) ),
            green: CGFloat( Float(greenColor+1) / Float(256) ),
            blue: CGFloat( Float(blueColor+1) / Float(256) ),
            alpha: 1.0
        )
        return true
    }
