宏定义

    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:


    项目中的宏架构.png

    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)
    • 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"
    • 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
    #ifdef DEBUG
    #define LMLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), PRETTY_FUNCTION, LINE, ##VA_ARGS);
    #else
    #define LMLog(...)
    #endif

    #define WeakSelf(weakSelf)  __weak __typeof(&*self)weakSelf = self;

    *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, 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"]

    这样导入宏,简单明了
