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
#define kScreenWidth \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width)
#define kScreenHeight \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.height)
#define kScreenSize \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? CGSizeMake([UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale,[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale) : [UIScreen mainScreen].bounds.size)

blue:((float)(rgbValue & 0xFF)) / 255.0 alpha:1.0]

//弱引用/强引用
#define kWeakSelf(type) __weak typeof(type) weak##type = type;

#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
