年夜家都是曉得應用宏不只便利，並且可以進步開辟效力。上面總結了IOS開辟進程中的一些經常使用宏，會連續的往外面添加。

Objective-C

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

//獲得屏幕寬度與高度
#define kScreenWidth \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width)
#define kScreenHeight \

//弱援用/強援用
#define kWeakSelf(type) __weak typeof(type) weak##type = 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)

//獲得一段時光距離
#define kStartTime CFAbsoluteTime start = CFAbsoluteTimeGetCurrent();

1.界說尺寸類的宏

DimensMacros.h
//狀況欄高度
#define STATUS_BAR_HEIGHT 20
//NavBar高度
#define NAVIGATION_BAR_HEIGHT 44
//狀況欄 ＋ 導航欄 高度
#define STATUS_AND_NAVIGATION_HEIGHT ((STATUS_BAR_HEIGHT) + (NAVIGATION_BAR_HEIGHT))

#define kPathSplashScreen      [kPathCache stringByAppendingPathComponent:@"splashScreen"]
#endif

3.對象類的宏

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)


// 獲得RGB色彩
#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]]))


//角度轉弧度
#define DEGREES_TO_RADIANS(d) (d * M_PI / 180)

//年夜於等於7.0的IOS版本
#define IOS7_OR_LATER SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")

//年夜於等於8.0的ios版本
#define iOS8_OR_LATER SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")

//iOS6時，導航VC中view的肇端高度
#define YH_HEIGHT (iOS7_OR_LATER ? 64:0)

//獲得體系時光戳
#define getCurentTime [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]]

4.告訴Notification相干的宏

NotificationMacros.h
//體系Notification界說

#define TNCancelFavoriteProductNotification   @"TNCancelFavoriteProductNotification"   //撤消珍藏時
#define TNMarkFavoriteProductNotification    @"TNMarkFavoriteProductNotification"    //標志珍藏時

#define kNotficationDownloadProgressChanged   @"kNotficationDownloadProgressChanged"   //下載進度變更
#define kNotificationPauseDownload       @"kNotificationPauseDownload"        //暫停下載
#define kNotificationStartDownload       @"kNotificationStartDownload"        //開端下載

#define kNotificationDownloadSuccess      @"kNotificationDownloadSuccess"       //下載勝利
#define kNotificationDownloadFailed       @"kNotificationDownloadFailed"       //下載掉敗
#define kNotificationDownloadNewMagazine    @"kNotificationDownloadNewMagazine"
辦事端API接口的宏

APIStringMacros.h
//////////////////////////////////////////////////////////////////////////////////////////////////
//接口稱號相干

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

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

#endif

//接口
#define GET_CONTENT_DETAIL   @"channel/getContentDetail" //獲得內容概況(含上一個和下一個)

#define GET_COMMENT_LIST    @"comment/getCommentList"  //獲得評論列表

#define COMMENT_LOGIN      @"comment/login"      //獲得評論列表

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

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

#define LOGINOUT        @"common/logout"      //登出
還有許多其他類型的宏，此處紛歧一羅列

創立一個import一切宏相干的文件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項目標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
