iOS 开发常用宏总结 - 快网idc优惠网

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 \\

服务端API接口的宏

APIStringMacros.h

//////////////////////////////////////////////////////////////////////////////////////////////////

//接口名称相关

#ifdef DEBUG

#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
