iOS 开发常用宏总结

大家都是知道使用宏不仅方便，而且可以提高开发效率。下面总结了ios开发过程中的一些常用宏，会持续的往里面添加。

objective-c

//字符串是否为空
#define kstringisempty(str) ([str iskindofclass:[nsnull class]] || str == nil || [str length] < 1 ? yes : no )
//数组是否为空
#define karrayisempty(array) (array == nil || [array iskindofclass:[nsnull class]] || array.count == 0)
//字典是否为空
#define kdictisempty(dic) (dic == nil || [dic iskindofclass:[nsnull class]] || dic.allkeys == 0)
//是否是空对象
#define kobjectisempty(_object) (_object == nil \
|| [_object iskindofclass:[nsnull class]] \
|| ([_object respondstoselector:@selector(length)] && [(nsdata *)_object length] == 0) \
|| ([_object respondstoselector:@selector(count)] && [(nsarray *)_object count] == 0))

//获取屏幕宽度与高度

4.通知notification相关的宏

notificationmacros.h
//系统notification定义

#define tncancelfavoriteproductnotification   @"tncancelfavoriteproductnotification"   //取消收藏时
#define tnmarkfavoriteproductnotification    @"tnmarkfavoriteproductnotification"    //标记收藏时

#define knotficationdownloadprogresschanged   @"knotficationdownloadprogresschanged"   //下载进度变化
#define knotificationpausedownload       @"knotificationpausedownload"        //暂停下载
#define knotificationstartdownload       @"knotificationstartdownload"        //开始下载

#define knotificationdownloadsuccess      @"knotificationdownloadsuccess"       //下载成功
#define knotificationdownloadfailed       @"knotificationdownloadfailed"       //下载失败
#define knotificationdownloadnewmagazine    @"knotificationdownloadnewmagazine"
服务端api接口的宏

apistringmacros.h
//////////////////////////////////////////////////////////////////////////////////////////////////
//接口名称相关

#ifdef debug
//debug状态下的测试api
#define api_base_url_string   @"http://boys.test.companydomain.com/api/"

#else
//release状态下的线上api
#define api_base_url_string   @"http://www.companydomain.com/api/"

#endif

//接口
#define get_content_detail   @"channel/getcontentdetail" //获取内容详情(含上一个和下一个)

#define get_comment_list    @"comment/getcommentlist"  //获取评论列表

#define comment_login      @"comment/login"      //获取评论列表

#define comment_publish     @"comment/publish"     //发布评论

#define comment_delete     @"comment/delcomment"    //删除评论

#define loginout        @"common/logout"      //登出
还有很多其他类型的宏，此处不一一列举

创建一个import所有宏相关的文件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项目的pch文件中，导入macros.h文件

xcodeprojectname-prefix.pch
#ifdef __objc__
  #import <uikit/uikit.h>
  #import <foundation/foundation.h>
  #import "macros.h"
#endif
