设置html 导图颜色

extension UIColor {

/// 用十六进制颜色创建UIColor

///

/// - Parameter hexColor: 十六进制颜色 (0F0F0F)

convenience init(hexColor: String) {

// 存储转换后的数值

var red:UInt32 = 0, green:UInt32 = 0, blue:UInt32 = 0

// 分别转换进行转换

Scanner(string: hexColor[0..<2]).scanHexInt32(&red)

Scanner(string: hexColor[2..<4]).scanHexInt32(&green)

Scanner(string: hexColor[4..<6]).scanHexInt32(&blue)

self.init(red: CGFloat(red)/255.0, green: CGFloat(green)/255.0, blue: CGFloat(blue)/255.0, alpha: 1.0)

}

convenience init(hexColor: String, alpha: CGFloat) {

// 存储转换后的数值

var red:UInt32 = 0, green:UInt32 = 0, blue:UInt32 = 0

// 分别转换进行转换

Scanner(string: hexColor[0..<2]).scanHexInt32(&red)

Scanner(string: hexColor[2..<4]).scanHexInt32(&green)

Scanner(string: hexColor[4..<6]).scanHexInt32(&blue)

self.init(red: CGFloat(red)/255.0, green: CGFloat(green)/255.0, blue: CGFloat(blue)/255.0, alpha: alpha)

}

}
