如何使用XCGLogger输出调用方法的名称？

Question

我已经创建了一个MyLogger类，它将参数传递给XCGLogger以输出日志。我为XCGLogger的showFileName和dateshowFunctionName指定了showFileName，但它总是输出MyLogger自己的文件名和方法名。有没有办法让它输出调用者的文件名和方法名？

这就是现在的输出。

2022/06/17,11:44:54.054 [Debug] [MyLogger.swift] logWrite(level:message:) > New user is comming.
2022/06/17,11:44:54.054 [Warning] [MyLogger.swift] logWrite(level:message:) > Invaild login_name or password. [login_name:marverick] failed 1 times.
2022/06/17,11:44:58.058 [Info] [MyLogger.swift] logWrite(level:message:) > Login success. Hello maverick!

我想要的是这个。

2022/06/17,11:44:54.054 [Debug] [Login.swift] top() > New user is comming.
2022/06/17,11:44:54.054 [Warning] [Auth.swift] authCheck(login_name:password:) > Invaild login_name or password. [login_name:marverick] failed 1 times.
2022/06/17,11:44:58.058 [Info] [Main.swift] main(param:) > Login success. Hello maverick!

我的密码是这个。它似乎有点长，但我不知道是什么原因造成的问题，所以我没有缩写太多。

import Foundation
import SSZipArchive
import XCGLogger

publc class MyLogger: NSObject, URLSessionTaskDelegate {
    static public func logWrite(level: LOGLEVEL, message:String) {
        let logSetUp = settings.logger()
        let fileName = createFileName()
        let log = XCGLogger.default
       
        do {
            let folderName = FileManager.default.urls(for:.libraryDirectory,in:.userDomainMask).first?.appendingPathComponent("Logs",isDirectory:true)
            try FileManager.default.createDirectory(at: folderName!, withIntermediateDirectories: true, attributes: nil)
        }
        catch{
            MyLogger.logWrite(level: .ERROR, message: error.localizedDescription)
        }
       
        let path = FileManager.default.urls(for: .libraryDirectory,in: .userDomainMask).first?.appendingPathComponent("Logs", isDirectory: false).appendingPathComponent(fileName + ".log")
        log.dateFormatter?.dateFormat = logSetUp.dateformat
       
        let autorotateFileDestination = AutoRotatingFileDestination(writeToFile: path, identifier: log.identifier, shouldAppend: logSetUp.shouldappend, maxTimeInterval: logSetUp.targetmaxtimeinterval, targetMaxLogFiles: logSetUp.targetmaxlogfiles)
        autorotateFileDestination.showLogIdentifier = logSetUp.showlogidentifier
        autorotateFileDestination.showFunctionName = logSetUp.showfunctionname
        autorotateFileDestination.showThreadName = logSetUp.showthreadname
        autorotateFileDestination.showLevel = logSetUp.showlevel
        autorotateFileDestination.showFileName = logSetUp.showfilenames
        autorotateFileDestination.showLineNumber = logSetUp.showlinenumbers
        autorotateFileDestination.showDate = logSetUp.showdata
        log.add(destination: autorotateFileDestination)
       
        switch level {
        case .DEBUG:
            log.debug(message)
        case .INFO:
            log.info(message)
        case .WARNING:
            log.warning(message)
        case .ERROR:
            log.error(message)
        }
    }
    
    //other methods here
}

我没有得到答案，但这段代码给了我预期的结果。我从#file、#line和#function参数中获取调用者的信息，并将其添加为字符串。

import Foundation
import SSZipArchive
import XCGLogger

publc class MyLogger: NSObject, URLSessionTaskDelegate {
    static public func logWrite(level: LOGLEVEL, message:String, file: String = #file, line: Int = #line, function: String = #function) {

        //
        // no change here
        // 
       
        let callerFileName :String = String(file.split(separator: "/").last ?? "")
        let customMessage = "[\(callerFileName):\(line)] \(function) >> \(message)"
        switch level {
        case .DEBUG:
            log.debug(customMessage)
        case .INFO:
            log.info(customMessage)
        case .WARNING:
            log.warning(customMessage)
        case .ERROR:
            log.error(customMessage)
        }
    }
    
    //other methods here
}
