通过UIColor的extension方法 convenience init(hex8: UInt32)中，可以看到传入的值计算之后得到的red，green，blue，alpha，都不对

最后修改为
let alpha = CGFloat((hex8 & 0xFF000000) >> 24) / divisor
let red = CGFloat((hex8 & 0x00FF0000) >> 16) / divisor
let green = CGFloat((hex8 & 0x0000FF00) >> 8) / divisor
let blue = CGFloat( hex8 & 0x000000FF ) / divisor
