问题描述

我正在尝试重写我的日志类,我想知道如何在swift文件中替换 PRETTY_FUNCTION 或NSStringFromSelector(_cmd)以跟踪方法调用?

$查看我刚刚发布的一个新库: nofollow> https://github.com/DaveWoodCom/XCGLogger



这是Swift的调试日志库。



能够使用 #function 宏的关键是将它们设置为日志功能的默认值。然后编译器将使用期望值填充它们。

  func log(logMessage:String,functionName:String = #function) {
print(\(functionName):\(logMessage))
}

然后只需调用:

  log(my message)



它的工作原理如下:

  whateverFunction():我的消息

I am trying to rewrite my logging class and I would like to know how to substitute PRETTY_FUNCTION or NSStringFromSelector(_cmd) in a swift file in order to track the method calls?

解决方案

Check out a new library I've just published: https://github.com/DaveWoodCom/XCGLogger

It's a debug logging library for Swift.

The key to being able to use the #function macros, is to set them as default values to your logging function. The compiler will then fill them in using the expected values.

func log(logMessage: String, functionName: String = #function) {
    print("\(functionName): \(logMessage)")
}

Then just call:

log("my message")

And it works as expected giving you something like:

whateverFunction(): my message
