选择1，生成 mars.framework, 我们主要是使用头文件目录。

将 mars.xcodeproj 作为子工程，添加为依赖项

通过 cmake 生成的 project 定义了生成 mars.framework 的几个相关target， 将 mars.xcodeproj 设置为子工程，
主工程依赖 mars.xcodeproj 定义的target，即可实现 xlog 的源码调试。

  1. create new macOS project: xlog-test, selcte language: Objective-C
  2. mars.xcodeproj 添加到 xlog-test 工程中
  3. 将 mars.framework/Headers 拷贝到 xlog-test 根目录
  4. xlog-test 配置 header search paths， 值为 $(SRCROOT)/Headers

  5. xlog-test 配置 linked libraries

  6. 添加辅助代码，从 MacDemo 中获取， 拷贝到 xlog-test 工程中

  7. LogHelper 中添加 setup 方法，用于初始化 xlog

    + (void)setup {
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
        NSString *libraryDirectory = [paths firstObject];
        
        // init xlog
    #if DEBUG
        xlogger_SetLevel(kLevelDebug);
        mars::xlog::appender_set_console_log(true);
    #else
        xlogger_SetLevel(kLevelInfo);
        appender_set_console_log(false);
    #endif
        mars::xlog::XLogConfig config;
        config.mode_ = mars::xlog::kAppenderAsync;
        config.logdir_ = [[libraryDirectory stringByAppendingString:@"/log/"] UTF8String];
        config.nameprefix_ = "Test";
        config.pub_key_ = "";
        config.compress_mode_ = mars::xlog::kZlib;
        config.compress_level_ = 0;
        config.cachedir_ = "";
        config.cache_days_ = 0;
        appender_open(config);
    }
  8. main.m 中初始化调用

    #import <Cocoa/Cocoa.h>
    #import "LogHelper.h"
    int main(int argc, const char * argv[]) {
        @autoreleasepool {
            [LogHelper setup];
        }
        return NSApplicationMain(argc, argv);
    }
  9. 用LogUtil.h中宏定义打log
    1
    LOG_ERROR(kModuleViewController, @"this is a test log!");
  10. 愉快地断点，调试吧
