Tag:  iOS开发 ,iOS宏定义
这篇文章主要给大家介绍了关于iOS中常用的宏定义的相关资料,例如UI元素、Log、系统、颜色类等等的示例代码,文中介绍地方非常详细,需要的朋友可以参考借鉴,下面随着小编来一起学习学习吧

广州快乐十分开奖记录 www.2hyn.net 前言
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

//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

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

#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)

#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

但是太多的宏定义会拖慢编译速度
