这篇文章是我从开源中国转载过来的,说下转载原因,就是开发中
需要跟同事配合,但是每个人都有每个人得编程习惯,但是都各不相同,比如有些人喜欢这样定义
#define screenW [UIScreen mainScreen].bounds.size.width
有人喜欢
#define Width_Screen [UIScreen mainScreen].bounds.size.width...
为了让大家更好地协同工作,编码必须要有一定的规范,这就是我转过来的原因.当然,不一定按照这个样式写,但一定要有规范,每个程序员都遵守规范,这样利人利己.
宏定义在很多方面都会使用，例如定义高度、判断iOS系统、工具类，还有诸如文件路径、服务端api接口文档。为了对宏能够快速定位和了解其功能，我们最好在定义的时候将其放入特定的头文件中，下面我抛砖引玉，对一些常用的宏进行分类、分文件定义，希望对大家有所帮助。
1 .定义尺寸类的宏
DimensMacros.h
//状态栏高度
#define STATUS_BAR_HEIGHT 20
//NavBar高度
#define NAVIGATION_BAR_HEIGHT 44
//状态栏 ＋ 导航栏 高度
#define STATUS_AND_NAVIGATION_HEIGHT ((STATUS_BAR_HEIGHT) + (NAVIGATION_BAR_HEIGHT))
//屏幕 rect
#define SCREEN_RECT ([UIScreen mainScreen].bounds)
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)
#define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATION_BAR_HEIGHT - STATUS_BAR_HEIGHT)
//屏幕分辨率
#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))
//广告栏高度
#define BANNER_HEIGHT 215
#define STYLEPAGE_HEIGHT 21
#define SMALLTV_HEIGHT 77
#define SMALLTV_WIDTH 110
#define FOLLOW_HEIGHT 220
#define SUBCHANNEL_HEIGHT 62
2 .定义沙盒目录文件的宏
PathMacros.h
//文件目录
#define kPathTemp NSTemporaryDirectory()
#define kPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]
#define kPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0]
#define kPathSearch [kPathDocument stringByAppendingPathComponent:@"Search.plist"]
#define kPathMagazine [kPathDocument stringByAppendingPathComponent:@"Magazine"]
#define kPathDownloadedMgzs [kPathMagazine stringByAppendingPathComponent:@"DownloadedMgz.plist"]
#define kPathDownloadURLs [kPathMagazine stringByAppendingPathComponent:@"DownloadURLs.plist"]
#define kPathOperation [kPathMagazine stringByAppendingPathComponent:@"Operation.plist"]
#define kPathSplashScreen [kPathCache stringByAppendingPathComponent:@"splashScreen"]
#endif
3 .工具类的宏
UtilsMacros.h
//Log utils marco
#define ALog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);
#ifdef DEBUG
#define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);
#else
#define DLog(...)
#endif
#ifdef DEBUG
#define ULog(...)
//#define ULog(fmt, ...) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"%s\n [Line %d] ", __PRETTY_FUNCTION__, __LINE__] message:[NSString stringWithFormat:fmt, ##__VA_ARGS__] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; }
#else
#define ULog(...)
#endif
//System version utils
#define SYSTEM_VERSION_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)
// 获取RGB颜色
#define RGBA(r,g,b,a) [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:a]
#define RGB(r,g,b) RGBA(r,g,b,1.0f)
#define IsPortrait ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)
#define IsNilOrNull(_ref) (((_ref) == nil) || ([(_ref) isEqual:[NSNull null]]))
//角度转弧度
#define DEGREES_TO_RADIANS(d) (d * M_PI / 180)
//大于等于7.0的ios版本
#define iOS7_OR_LATER SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")
//大于等于8.0的ios版本
#define iOS8_OR_LATER SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")
//iOS6时，导航VC中view的起始高度
#define YH_HEIGHT (iOS7_OR_LATER ? 64:0)
//获取系统时间戳
#define getCurentTime [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]]
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...
作者在网络请求的时候,和我的请求思路不太一样,我的习惯如下:
/*
开发环境用户版：xx.x.x.xxx:7272
测试环境IOS用户版：xx.x.x.xxx:8282
测试环境android用户版：xx.x.x.xxx:9292
线上环境: userapi.xxxx.xxx
性能测试环境 ： xx.x.x.xxx:6262
..............
本地测试 10.0.0.110:20081
*/
#define URL_SERVER @"10.0.0.247:9292"
/**
* 搜索附近商户URL
*/
#define URL_SEARCHSHOP [NSString stringWithFormat:@"http://%@/searchshops",URL_SERVER]
/**
* 登陆URL
*/
#define URL_LOGIN [NSString stringWithFormat:@"http://%@/login",URL_SERVER]
/**
* 注册URL
*/
#define URL_REGISTER [NSString stringWithFormat:@"http://%@/register",URL_SERVER]
......
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
现在项目没有使用pch,需要的地方#import下头文件就ok...
