//介面名稱相關
#ifdef DEBUG
//Debug狀態下的測試API
#define API_BASE_URL_STRING   @"http://boys.test.companydomain.com/api/"
#else
//Release狀態下的線上API
#define API_BASE_URL_STRING   @"http://www.companydomain.com/api/"
#endif
//介面
#define GET_CONTENT_DETAIL   @"channel/getContentDetail" //獲取內容詳情(含上一個和下一個)
#define GET_COMMENT_LIST    @"comment/getCommentList"  //獲取評論列表
#define COMMENT_LOGIN      @"comment/login"      //獲取評論列表
#define COMMENT_PUBLISH     @"comment/publish"     //釋出評論
#define COMMENT_DELETE     @"comment/delComment"    //刪除評論
#define LOGINOUT        @"common/logout"      //登出
還有很多其他型別的巨集，此處不一一列舉
建立一個import所有巨集相關的檔案Macros.h
Macros.h
#import "UtilsMacros.h"
#import "APIStringMacros.h"
#import "DimensMacros.h"
#import "NotificationMacros.h"
#import "SharePlatformMacros.h"
#import "StringMacros.h"
#import "UserBehaviorMacros.h"
#import "PathMacros.h"
在xcode專案的pch檔案中，匯入Macros.h檔案
XcodeProjectName-Prefix.pch
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import "Macros.h"
#endif
