宏定义
2010 年 11 月 11 日
iOS不倒,博客不停
这段时间会玩一个项目(项目名先不说吧,留点悬念),所以会陆陆续续总结一些东西.写完这个项目,考虑换家公司.
今天整理一些自己的项目里零零碎碎的东西,发现有些东西太杂太乱,就是定义的全局.这里一个宏,那边一个 #define ,发现这东西会左右引用,很影响性能
我给宏同意规划分类如下:
一看就知道是为了分工明确,方便添加删除..管理,这样也就能减少各种杂乱应用
下面分开介绍各种宏:
- Macros.h
这里面就放各各宏的头文件,然后在PCH文件中引用着这个一个头文件就OK
#import “DimensMacros.h”
#import “UtilsMacros.h”
#import “PathMacros.h”
#import “NotificationMacros.h”
#import “APIStringMacros.h”
- APIStringMacros_h(服务端API接口的宏)
这里面主要放一些API相关的东西:比如你请求网络的接口hostname,port还有一些第三方的关键字段:极光推送的appkey….
- DimensMacros.h (定义尺寸类的宏)
这里面定义一些尺寸相关的宏:
#pragma mark - 系统UI #define kNavigationBarHeight 44 #define kStatusBarHeight 20 #define kTopBarHeight 64 #define kToolBarHeight 44 #define kTabBarHeight 49 #define kiPhone4_W 320 #define kiPhone4_H 480 #define kiPhone5_W 320 #define kiPhone5_H 568 #define kiPhone6_W 375 #define kiPhone6_H 667 #define kiPhone6P_W 414 #define kiPhone6P_H 736 /*** 当前屏幕宽度 */ #define kScreenWidth [[UIScreen mainScreen] bounds].size.width /*** 当前屏幕高度 */ #define kScreenHeight [[UIScreen mainScreen] bounds].size.height /*** 普通字体 */ #define kFont(size) [UIFont systemFontOfSize:size] /*** 粗体 */ #define kBoldFont(size) [UIFont boldSystemFontOfSize:size] #define kLineHeight (1 / [UIScreen mainScreen].scale) 复制代码
- NotificationMacros.h(通知Notification相关宏)
这里面放一些关于通知定义的宏
#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" 复制代码
- UtilsMacros_h(工具类的宏)
这里面存放一些方便开发的工具:**颜色,打印,单利,版本… **
// 日志输出

*PathMacros.h(沙河路径宏)
这里面是一些沙河路径,还有一些plist路径
//文件目录
#define kPathTemp NSTemporaryDirectory()
#define kPathDocument
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]
#define kPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory,
