log日志管理，方便后面使用

public class WLog: NSObject {
    static func i<T>(_ message: T, file: String = #file, method: String = #function, line: Int = #line){
        Log.info.cat(message)
    }
    
    static func s<T>(_ message: T, file: String = #file, method: String = #function, line: Int = #line){
        Log.success.cat(message)
    }
    
    static func e<T>(_ message: T, file: String = #file, method: String = #function, line: Int = #line){
        Log.error.cat(message)
    }
    
    static func w<T>(_ message: T, file: String = #file, method: String = #function, line: Int = #line){
        Log.warning.cat(message)
    }
}

enum Log {
    case info
    case success
    case error
    case warning
}

extension Log {
    // 輸出默認(rèn)info的日志
    static func cat<T>(_ message: T, file: String = #file, method: String = #function, line: Int = #line) {
        self.info.cat(message)
    }

    // 輸入日志，根據(jù)類型，區(qū)別符號(hào)
    //
    // - Parameters:
    //- message: 顯示的信息
    func cat<T>(_ message: T, file: String = #file, method: String = #function, line: Int = #line) {
        #if DEBUG
            var log: String
            switch self {
            case .info:
                log = " ?? - " + "\(message)"
            case .success:
                log = " ? - " + "\(message)"
            case .error:
                log = " ? - " + "\(message)"
            case .warning:
                log = " ?? - " + "\(message)"
            }
            print("\((file as NSString).lastPathComponent)[\(line)],\(method):\(log)")
        #endif
    }
