How can I use UIColorFromRGB in Swift?

Question

In Objective-C, we use this code to set RGB color codes for views:

#define UIColorFromRGB(rgbValue)        
[UIColor colorWithRed:((float)((rgbValue & 0x         


        

Answer 1

solution for argb format:

//  UIColorExtensions.swift
import UIKit
extension UIColor {

    convenience init(argb: UInt) {
        self.init(
            red: CGFloat((argb & 0xFF0000) >> 16) / 255.0,
            green: CGFloat((argb & 0x00FF00) >> 8) / 255.0,
            blue: CGFloat(argb & 0x0000FF) / 255.0,
            alpha: CGFloat((argb & 0xFF000000) >> 24) / 255.0
        )
    }
}

usage:

var clearColor: UIColor = UIColor.init(argb: 0x00000000)
var redColor: UIColor = UIColor.init(argb: 0xFFFF0000)
