swift 宏定义

1.自定义 Log输出

func DLog<T>(message: T, fileName: String = #file, methodName: String =  #function, lineNumber: Int = #line){    #if DEBUG        let str: String = ((fileName as NSString).pathComponents.last?.replacingOccurrences(of: "", with: "swift"))!        print("\(str)---\(methodName)---[\(lineNumber)行]======>\(message)")    #endif}

2.颜色

<1>rgb

func rgb(red: CGFloat, green: CGFloat, blue: CGFloat) -> UIColor {    return UIColor.init(red: red/255.0, green: green/255.0, blue: blue/255.0, alpha: 1.0)}func rgba(red: CGFloat, green: CGFloat, blue: CGFloat, alpha: CGFloat) -> UIColor {    return UIColor.init(red: red/255.0, green: green/255.0, blue: blue/255.0, alpha: alpha/1.0)}
