Want to use hex color values in swift? To simplify the conversion, let’s create an initializer that takes integer (0 – 255) values. Use the following Swift example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | extension UIColor { convenience init(red: Int, green: Int, blue: Int) { assert(red >= 0 && red <= 255, "Invalid red component") assert(green >= 0 && green <= 255, "Invalid green component") assert(blue >= 0 && blue <= 255, "Invalid blue component") self.init(red: CGFloat(red) / 255.0, green: CGFloat(green) / 255.0, blue: CGFloat(blue) / 255.0, alpha: 1.0) } convenience init(rgb: Int) { self.init( red: (rgb >> 16) & 0xFF, green: (rgb >> 8) & 0xFF, blue: rgb & 0xFF ) } } |
