我正在使用此代码从十六进制值创建UIColor.它的工作完美.

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(netHex:Int) {
   self.init(red:(netHex >> 16) & 0xff, green:(netHex >> 8) & 0xff, blue:netHex & 0xff)
}
}

用法:

var textColor = UIColor(netHex: …
