大家都是知道使用宏不僅方便，而且可以提高開發效率。下面總結了iOS開發過程中的一些常用宏，會持續的往裡面添加。

Objective-C

//字符串是否為空
#define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO )
//數組是否為空
#define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0)
//字典是否為空
#define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0)
//是否是空對象
#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))

//獲取屏幕寬度與高度
#define kScreenWidth \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width)
#define kScreenHeight \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.height)
#define kScreenSize \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? CGSizeMake([UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale,[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale) : [UIScreen mainScreen].bounds.size)

green:((float)((rgbValue & 0xFF00) >> 8)) / 255.0 \
blue:((float)(rgbValue & 0xFF)) / 255.0 alpha:1.0]

//弱引用/強引用
#define kWeakSelf(type) __weak typeof(type) weak##type = type;
#define kStrongSelf(type) __strong typeof(type) type = weak##type;

//由角度轉換弧度
#define kDegreesToRadian(x)  (M_PI * (x) / 180.0)
//由弧度轉換角度
#define kRadianToDegrees(radian) (radian * 180.0) / (M_PI)

//獲取一段時間間隔
#define kStartTime CFAbsoluteTime start = CFAbsoluteTimeGetCurrent();
#define kEndTime NSLog(@"Time: %f", CFAbsoluteTimeGetCurrent() - start)

1.定義尺寸類的宏

DimensMacros.h
//狀態欄高度
#define STATUS_BAR_HEIGHT 20
//NavBar高度
#define NAVIGATION_BAR_HEIGHT 44
//狀態欄 ＋ 導航欄 高度

#define iOS8_OR_LATER SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")

//iOS6時，導航VC中view的起始高度
#define YH_HEIGHT (iOS7_OR_LATER ? 64:0)

//獲取系統時間戳
#define getCurentTime [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]]

4.通知Notification相關的宏

NotificationMacros.h
//系統Notification定義

#define TNCancelFavoriteProductNotification   @"TNCancelFavoriteProductNotification"   //取消收藏時
#define TNMarkFavoriteProductNotification    @"TNMarkFavoriteProductNotification"    //標記收藏時

#define kNotficationDownloadProgressChanged   @"kNotficationDownloadProgressChanged"   //下載進度變化
#define kNotificationPauseDownload       @"kNotificationPauseDownload"        //暫停下載
#define kNotificationStartDownload       @"kNotificationStartDownload"        //開始下載

#define kNotificationDownloadSuccess      @"kNotificationDownloadSuccess"       //下載成功
#define kNotificationDownloadFailed       @"kNotificationDownloadFailed"       //下載失敗
#define kNotificationDownloadNewMagazine    @"kNotificationDownloadNewMagazine"
服務端API接口的宏

APIStringMacros.h
//////////////////////////////////////////////////////////////////////////////////////////////////
//接口名稱相關

#ifdef DEBUG
//Debug狀態下的測試API
#define API_BASE_URL_STRING   @"http://boys.test.companydomain.com/api/"

#else
//Release狀態下的線上API
#define API_BASE_URL_STRING   @"http://www.companydomain.com/api/"

#endif

//接口
#define GET_CONTENT_DETAIL   @"channel/getContentDetail" //獲取內容詳情(含上一個和下一個)

#define GET_COMMENT_LIST    @"comment/getCommentList"  //獲取評論列表

#define COMMENT_LOGIN      @"comment/login"      //獲取評論列表

#define COMMENT_PUBLISH     @"comment/publish"     //發布評論

#define COMMENT_DELETE     @"comment/delComment"    //刪除評論

#define LOGINOUT        @"common/logout"      //登出
還有很多其他類型的宏，此處不一一列舉

創建一個import所有宏相關的文件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項目的pch文件中，導入Macros.h文件

XcodeProjectName-Prefix.pch
#ifdef __OBJC__
  #import <UIKit/UIKit.h>
  #import <Foundation/Foundation.h>
  #import "Macros.h"
#endif
