前言

宏定義在C系開發(fā)中可以說占有舉足輕重的作用,為了簡化開發(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

//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//強(qiáng)引用#define StrongWithNameAndObject(obj,name) __strong typeof(obj) strong##name = obj

總結(jié)

以上就是這篇文章的全部內(nèi)容了,希望本文的內(nèi)容對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,如果有疑問大家可以留言交流,謝謝大家對VEVB武林網(wǎng)的支持。
