宏定义在C系开发中可以说占有举足轻重的作用，为了简化开发流程，提升工作效率，收集了一些平时常用的宏定义，今后会不定期更新

1.UI元素

//NavBar高度
#define NAVIGATIONBAR_HEIGHT 44

//StatusBar高度
#define STATUSBAR_HEIGHT 20

//获取屏幕 宽度、高度
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

//内容视图高度
#define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATIONBAR_HEIGHT - STATUSBAR_HEIGHT)

//KWindow
#define KWINDOW [UIApplication sharedApplication].keyWindow

//屏幕分辨率
#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))

//状态栏 ＋ 导航栏 高度
#define STATUS_AND_NAVIGATION_HEIGHT ((STATUSBAR_HEIGHT) + (NAVIGATIONBAR_HEIGHT))

2.Log

//(在系统Log基础之上，加入自定义的相关信息)
#define NSLog(format, ...) do {            \
fprintf(stderr, "<%s : %d> %s\n",           \
[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], \
__LINE__, __func__);              \
(NSLog)((format), ##__VA_ARGS__);           \
fprintf(stderr, "-------\n");            \
} while (0)

3.系统

//获取当前系统版本
#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]
#define CurrentSystemVersion [[UIDevice currentDevice] systemVersion]

//获取当前系统语言
#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])

//判断是不是真机
#if TARGET_OS_IPHONE
 //iPhone Device
#endif

//判断是不是模拟器
#if TARGET_IPHONE_SIMULATOR
 //iPhone Simulator
#endif

//是否在ARC环境下
#if __has_feature(objc_arc)
 //compiling with ARC
#else
 //compiling without ARC
#endif

//判断是否为iPhone
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

//判断是否为iPad
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

//判断是否为ipod
#define IS_IPOD ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])

//判断是否为iPhone 5(S)(E)
#define iPhone5SE [[UIScreen mainScreen] bounds].size.width == 320.0f &&[[UIScreen mainScreen] bounds].size.height == 568.0f

//判断是否为iPhone 6/6s
#define iPhone6_6s [[UIScreen mainScreen] bounds].size.width == 375.0f &&[[UIScreen mainScreen] bounds].size.height == 667.0f

//判断是否为iPhone 6Plus/6sPlus
#define iPhone6Plus_6sPlus [[UIScreen mainScreen] bounds].size.width == 414.0f && [[UIScreen mainScreen] bounds].size.height == 736.0f

//判断 iOS 或更高的系统版本
#define IOS_VERSION_6_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue]>=6.0)? (YES):(NO))
#define IOS_VERSION_7_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue]>=7.0)? (YES):(NO))
#define IOS_VERSION_8_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0)? (YES):(NO))
#define IOS_VERSION_9_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue]>=9.0)? (YES):(NO))
#define IOS_VERSION_10_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue]>=10.0)? (YES):(NO))

//系统版本工具
#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)

//检测是否是竖屏状态
#define IsPortrait ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)

4.颜色类

//带有RGBA的颜色设置
#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]

//设置随机颜色(调试时候很有用)
#define RandomColor [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]

//16进制颜色
#define RGB16Color(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

5.通知

//获取通知中心
#define NotificationCenter [NSNotificationCenter defaultCenter]

//快速发通知
#define Post_Notify(_notificationName, _obj, _userInfoDictionary) [[NSNotificationCenter defaultCenter] postNotificationName: _notificationName object: _obj userInfo: _userInfoDictionary];

//添加观察者
#define Add_Observer(_notificationName, _observer, _observerSelector, _obj) [[NSNotificationCenter defaultCenter] addObserver:_observer selector:@selector(_observerSelector) name:_notificationName object: _obj];

//移除观察者
#define Remove_Observer(_observer) [[NSNotificationCenter defaultCenter] removeObserver: _observer];

6.数据存储

//NSUserDefaults 实例化
#define USER_DEFAULT [NSUserDefaults standardUserDefaults]

//获取temp

//获取沙盒Cache
#define kPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask, YES) firstObject]

7.单例模式

#define SingleH(name) +(instancetype)share##name;

#if __has_feature(objc_arc)
//条件满足 ARC
#define SingleM(name) static id _instance;\
+(instancetype)allocWithZone:(struct _NSZone *)zone\
{\
static dispatch_once_t onceToken;\
dispatch_once(&onceToken, ^{\
_instance = [super allocWithZone:zone];\
});\
\
return _instance;\
}\
\
+(instancetype)share##name\
{\
return [[self alloc]init];\
}\
\
-(id)copyWithZone:(NSZone *)zone\
{\
return _instance;\
}\
\
-(id)mutableCopyWithZone:(NSZone *)zone\
{\
return _instance;\
}

#else
//MRC
#define SingleM(name) static id _instance;\
+(instancetype)allocWithZone:(struct _NSZone *)zone\
{\
static dispatch_once_t onceToken;\
dispatch_once(&onceToken, ^{\
_instance = [super allocWithZone:zone];\
});\
\
return _instance;\
}\
\
+(instancetype)share##name\
{\
return [[self alloc]init];\
}\
\
-(id)copyWithZone:(NSZone *)zone\
{\
return _instance;\
}\
\
-(id)mutableCopyWithZone:(NSZone *)zone\
{\
return _instance;\
}\
-(oneway void)release\
{\
}\
\
-(instancetype)retain\
{\
 return _instance;\
}\
\
-(NSUInteger)retainCount\
{\
 return MAXFLOAT;\
}
#endif

8.时间

//获取系统时间戳
#define CurentTime [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]]

9.权限

//获取相机权限状态
#define CameraStatus [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]
#define CameraDenied ((CameraStatus == AVAuthorizationStatusRestricted)||(CameraStatus == AVAuthorizationStatusDenied))
#define CameraAllowed (!CameraDenyed)

/** 定位权限*/
#define LocationStatus [CLLocationManager authorizationStatus];
#define LocationAllowed ([CLLocationManager locationServicesEnabled] && !((status == kCLAuthorizationStatusDenied) || (status == kCLAuthorizationStatusRestricted)))
#define LocationDenied (!LocationAllowed)

/** 消息推送权限*/
#define PushClose (([[UIDevice currentDevice].systemVersion floatValue]>=8.0f)?(UIUserNotificationTypeNone == [[UIApplication sharedApplication] currentUserNotificationSettings].types):(UIRemoteNotificationTypeNone == [[UIApplication sharedApplication] enabledRemoteNotificationTypes]))
#define PushOpen (!PushClose)

10.本地文件加载

#define LoadImage(file,type) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:type]]
#define LoadArray(file,type) [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:type]]
#define LoadDict(file,type) [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:type]]

11.Block

//弱引用
#define WeakWithNameAndObject(obj,name) __weak typeof(obj) weak##name = obj
//强引用
#define StrongWithNameAndObject(obj,name) __strong typeof(obj) strong##name = obj
