Swift中自定义Log

Swift中自定义Log

Swift中自定义Log：依次是类名.方法名.行号.内容.

func LTLog(funcName: String = #function,_ message: T,file: String = #file, line: Int = #line) {

​

   #if DEBUG

   let files = (file as NSString).lastPathComponent.replacingOccurrences(of: ".swift", with: "")

       print("\(files) --> \(funcName) -->  \(line) --> \(message) ")

   #endif

}

​

还要配置以下宏

假如我在一个函数中打印这个"我是靓仔"

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

       LTLog("撒大大的")

       return true

   }

​

最终会输出

AppDelegate.application(_:didFinishLaunchingWithOptions:)[23]:撒大大的

​

注:依次是类名.方法名.行号.内容.
