iOS中常用的巨集定義總結
阿新 • • 發佈：2018-12-17
這篇文章主要給大家介紹了關於iOS中常用的巨集定義的相關資料，例如UI元素、Log、系統、顏色類等等的示例程式碼，文中介紹地方非常詳細，需要的朋友可以參考借鑑，下面隨著小編來一起學習學習吧
前言 巨集定義在C系開發中可以說佔有舉足輕重的作用，為了簡化開發流程，提升工作效率，收集了一些平時常用的巨集定義，今後會不定期更新
1.UI元素
//NavBar高度 #define NAVIGATIONBAR_HEIGHT 44 //StatusBar高度 #define STATUSBAR_HEIGHT 20 //獲取螢幕 寬度、高度 #define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width) #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height) //內容檢視高度 #define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATIONBAR_HEIGHT - STATUSBAR_HEIGHT) //KWindow #define KWINDOW [UIApplication sharedApplication].keyWindow //螢幕解析度 #define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale)) //狀態列 ＋ 導航欄 高度 #define STATUS_AND_NAVIGATION_HEIGHT ((STATUSBAR_HEIGHT) + (NAVIGATIONBAR_HEIGHT))
2.Log
//(在系統Log基礎之上，加入自定義的相關資訊) #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
//獲取當前系統版本 #define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue] #define CurrentSystemVersion [[UIDevice currentDevice] systemVersion] //獲取當前系統語言 #define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0]) //判斷是不是真機 #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 #define IsPortrait ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait || [UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)
4.顏色類
//帶有RGBA的顏色設定
#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]
//設定隨機顏色(除錯時候很有用)
#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進位制顏色
#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]
//快速發通知
#define Post_Notify(_notificationName, _obj, _userInfoDictionary) [[NSNotificationCenter defaultCenter] postNotificationName: _notificationName object: _obj userInfo: _userInfoDictionary];
//新增觀察者
#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.資料儲存
//NSUserDefaults 例項化
#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.時間
//獲取系統時間戳
#define CurentTime [NSString stringWithFormat:@"%ld", (long)[[NSDate date] timeIntervalSince1970]]
9.許可權
//獲取相機許可權狀態
#define CameraStatus [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]
#define CameraDenied ((CameraStatus == AVAuthorizationStatusRestricted)||(CameraStatus == AVAuthorizationStatusDenied))
#define CameraAllowed (!CameraDenyed)
/** 定位許可權*/
#define LocationStatus [CLLocationManager authorizationStatus];
#define LocationAllowed ([CLLocationManager locationServicesEnabled] && !((status == kCLAuthorizationStatusDenied) || (status == kCLAuthorizationStatusRestricted)))
#define LocationDenied (!LocationAllowed)
/** 訊息推送許可權*/
#define PushClose (([[UIDevice currentDevice].systemVersion floatValue]>=8.0f)?(UIUserNotificationTypeNone == [[UIApplication sharedApplication] currentUserNotificationSettings].types):(UIRemoteNotificationTypeNone == [[UIApplication sharedApplication] enabledRemoteNotificationTypes]))
#define PushOpen (!PushClose)
10.本地檔案載入
#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
