How do I create a UIColor from RGBA?

Question

I want to use NSAttributedString in my project, but when I\'m trying to set color, which isn\'t from the standard set (redColor, blackColor

Answer 1

Since @Jaswanth Kumar asked, here's the Swift version from LSwift:

extension UIColor {
    convenience init(rgb:UInt, alpha:CGFloat = 1.0) {
        self.init(
            red: CGFloat((rgb & 0xFF0000) >> 16) / 255.0,
            green: CGFloat((rgb & 0x00FF00) >> 8) / 255.0,
            blue: CGFloat(rgb & 0x0000FF) / 255.0,
            alpha: CGFloat(alpha)
        )
    }
}

Usage: let color = UIColor(rgb: 0x112233)
