iOS宏定义的使用与规范

时间：2024-10-02 16:34:38

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

    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

.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

.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]]

.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

还有很多其他类型的宏，此处不一一列举
