iOS常用宏定義

1.UI元素

//NavBar高度#defineNAVIGATIONBAR_HEIGHT 44//StatusBar高度#defineSTATUSBAR_HEIGHT 20//獲取屏幕 寬度、高度#defineSCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)#defineSCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)//內(nèi)容視圖高度#defineCONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATIONBAR_HEIGHT - STATUSBAR_HEIGHT)//KWindow#defineKWINDOW [UIApplication sharedApplication].keyWindow//屏幕分辨率#defineSCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))//狀態(tài)欄 ＋ 導(dǎo)航欄 高度#defineSTATUS_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",? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? \[[[NSStringstringWithUTF8String:__FILE__] lastPathComponent] UTF8String],? \__LINE__, __func__);? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? \(NSLog)((format),##__VA_ARGS__);? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? \fprintf(stderr,"-------\n");? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? \}while(0)

4.顏色類

//帶有RGBA的顏色設(shè)置#defineCOLOR(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)試時候很有用)#defineRandomColor [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#defineRGB16Color(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#defineNotificationCenter [NSNotificationCenter defaultCenter]//快速發(fā)通知#definePost_Notify(_notificationName, _obj, _userInfoDictionary) [[NSNotificationCenter defaultCenter] postNotificationName: _notificationName object: _obj userInfo: _userInfoDictionary];//添加觀察者#defineAdd_Observer(_notificationName, _observer, _observerSelector, _obj) [[NSNotificationCenter defaultCenter] addObserver:_observer selector:@selector(_observerSelector) name:_notificationName object: _obj];//移除觀察者#defineRemove_Observer(_observer) [[NSNotificationCenter defaultCenter] removeObserver: _observer];

6.數(shù)據(jù)存儲

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\{\staticdispatch_once_tonceToken;\dispatch_once(&onceToken, ^{\_instance = [superallocWithZone:zone];\});\\return_instance;\}\\+(instancetype)share##name\{\return[[selfalloc]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\{\staticdispatch_once_tonceToken;\dispatch_once(&onceToken, ^{\_instance = [superallocWithZone:zone];\});\\return_instance;\}\\+(instancetype)share##name\{\return[[selfalloc]init];\}\\-(id)copyWithZone:(NSZone*)zone\{\return_instance;\}\\-(id)mutableCopyWithZone:(NSZone*)zone\{\return_instance;\}\-(onewayvoid)release\{\}\\-(instancetype)retain\{\return_instance;\}\\-(NSUInteger)retainCount\{\returnMAXFLOAT;\}#endif

8.時間

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

9.權(quán)限

//獲取相機(jī)權(quán)限狀態(tài)#defineCameraStatus [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]#defineCameraDenied ((CameraStatus == AVAuthorizationStatusRestricted)||(CameraStatus == AVAuthorizationStatusDenied))#defineCameraAllowed (!CameraDenyed)/** 定位權(quán)限*/#defineLocationStatus [CLLocationManager authorizationStatus];#defineLocationAllowed ([CLLocationManager locationServicesEnabled] && !((status == kCLAuthorizationStatusDenied) || (status == kCLAuthorizationStatusRestricted)))#defineLocationDenied (!LocationAllowed)/** 消息推送權(quán)限*/#definePushClose (([[UIDevice currentDevice].systemVersion floatValue]>=8.0f)?(UIUserNotificationTypeNone == [[UIApplication sharedApplication] currentUserNotificationSettings].types):(UIRemoteNotificationTypeNone == [[UIApplication sharedApplication] enabledRemoteNotificationTypes]))#definePushOpen (!PushClose)

10.本地文件加載

#defineLoadImage(file,type)[UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:fileofType:type]]#defineLoadArray(file,type)[NSArray arrayWithContentsOfFile:[[NSBundle mainBundle]pathForResource:fileofType:type]]#defineLoadDict(file,type)[NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle]pathForResource:fileofType:type]]

11.Block

//弱引用#defineWeakWithNameAndObject(obj,name)? __weak? typeof(obj) weak##name? = obj//強(qiáng)引用#defineStrongWithNameAndObject(obj,name) __strong typeof(obj) strong##name = obj
