宏定義在C系開發(fā)中可以說(shuō)占有舉足輕重的作用，為了簡(jiǎn)化開發(fā)流程，提升工作效率，收集了一些平時(shí)常用的宏定義，今后會(huì)不定期更新

1.UI元素

//NavBar高度
#define NAVIGATIONBAR_HEIGHT 44

//StatusBar高度
#define STATUSBAR_HEIGHT 20

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

//內(nèi)容視圖高度
#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))

//狀態(tài)欄 ＋ 導(dǎo)航欄 高度
#define STATUS_AND_NAVIGATION_HEIGHT ((STATUSBAR_HEIGHT) + (NAVIGATIONBAR_HEIGHT))

2.Log

//(在系統(tǒng)Log基礎(chǔ)之上，加入自定義的相關(guān)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.系統(tǒng)

//獲取當(dāng)前系統(tǒng)版本
#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]
#define CurrentSystemVersion [[UIDevice currentDevice] systemVersion]

//獲取當(dāng)前系統(tǒng)語(yǔ)言
#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])

//判斷是不是真機(jī)
#if TARGET_OS_IPHONE
 //iPhone Device
#endif

//判斷是不是模擬器
#if TARGET_IPHONE_SIMULATOR
 //iPhone Simulator
#endif

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

//判斷是否為iPhone
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

//判斷是否為iPad
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

//判斷是否為ipod
#define IS_IPOD ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])

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

//判斷是否為iPhone 6/6s
#define iPhone6_6s [[UIScreen mainScreen] bounds].size.width == 375.0f &&[[UIScreen mainScreen] bounds].size.height == 667.0f

//判斷是否為iPhone 6Plus/6sPlus
#define iPhone6Plus_6sPlus [[UIScreen mainScreen] bounds].size.width == 414.0f && [[UIScreen mainScreen] bounds].size.height == 736.0f

//判斷 iOS 或更高的系統(tǒng)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))

//系統(tǒng)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)

//檢測(cè)是否是豎屏狀態(tài)
#define IsPortrait ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)

4.顏色類

//帶有RGBA的顏色設(shè)置
#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]

//設(shè)置隨機(jī)顏色(調(diào)試時(shí)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進(jìn)制顏色
#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

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

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

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

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

6.數(shù)據(jù)存儲(chǔ)

//NSUserDefaults 實(shí)例化
#define USER_DEFAULT [NSUserDefaults standardUserDefaults]

//獲取temp
#define kPathTemp NSTemporaryDirectory()

//獲取沙盒Document
#define kPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) firstObject]

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

7.單例模式

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

#if __has_feature(objc_arc)
//條件滿足 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.時(shí)間

//獲取系統(tǒng)時(shí)間戳
#define CurentTime [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]]

9.權(quán)限

//獲取相機(jī)權(quán)限狀態(tài)
#define CameraStatus [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]
#define CameraDenied ((CameraStatus == AVAuthorizationStatusRestricted)||(CameraStatus == AVAuthorizationStatusDenied))
#define CameraAllowed (!CameraDenyed)

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

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

10.本地文件加載

#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
