数组是否为空

#define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0)

字典是否为空

#define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0)

是否是空对象

#define kObjectIsEmpty(_object) (_object == nil \
|| [_object isKindOfClass:[NSNull class]] \
|| ([_object respondsToSelector:@selector(length)] && [(NSData *)_object length] == 0) \
|| ([_object respondsToSelector:@selector(count)] && [(NSArray *)_object count] == 0))

获取屏幕宽度与高度 ( " \ ":连接行标志，连接上下两行 )

//屏宽
#define kScreenWidth \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width)
//屏高
#define kScreenHeight \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.height)
//屏的size(宽、高)
#define kScreenSize \
([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? CGSizeMake([UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale,[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale) : [UIScreen mainScreen].bounds.size)

#endif

The general purpose logger. This ignores logging levels.

#ifdef ITTDEBUG
#define ITTDPRINT(xx, ...) NSLog(@"%s(%d): " xx, __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)

#else
#define ITTDPRINT(xx, ...) ((void)0)
#endif

打印当前方法的名称

#define ITTDPRINTMETHODNAME() ITTDPRINT(@"%s", __PRETTY_FUNCTION__)

Log-level based logging macros.

#define ITTAssert(condition, ...)                                      \
 do {                                                                      \
 if (!(condition)) {                                                    \
[NSAssertionHandler currentHandler]                                  \

} while(0)

系统

是否iPad

#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

是iPad还是iPhone

#define someThing (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)? ipad: iphone

获取系统版本

#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]

#define CurrentSystemVersion [[UIDevice currentDevice] systemVersion]

获取当前语言

#define CurrentLanguage (［NSLocale preferredLanguages] objectAtIndex:0])

判断设备是否是Retina屏、是否为iPone 5、是否是iPad

#define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] \
? CGSizeEqualToSize(CGSizeMake(640, 960), ［UIScreen mainScreen] currentMode].size) : NO)


#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] \
? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)

#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

//iphone型号：4、5、 6、6plus
#define SCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width)
#define SCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height)
#define SCREEN_MAX_LENGTH (MAX(SCREEN_WIDTH, SCREEN_HEIGHT))
#define SCREEN_MIN_LENGTH (MIN(SCREEN_WIDTH, SCREEN_HEIGHT))
#define IS_IPHONE_4_OR_LESS (IS_IPHONE && SCREEN_MAX_LENGTH < 568.0)
#define IS_IPHONE_5 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)
#define IS_IPHONE_6 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)
#define IS_IPHONE_6P (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)

判断设备的操做系统是不是ios7

#define IOS7 ([[UIDevice currentDevice].systemVersion doubleValue] >= 7.0]

判断当前设备是不是iphone5 （远古时期，单纯判断高度。。）
```
#define kScreenIphone5 (([[UIScreen mainScreen] bounds].size.height)>=568)
```

获取当前屏幕的高度

#define kMainScreenHeight ([UIScreen mainScreen].applicationFrame.size.height)

获取当前屏幕的宽度

#define kMainScreenWidth  ([UIScreen mainScreen].applicationFrame.size.width)

iOS9之后使用“[UIScreen mainScreen].bounds”属性

定义一个“define”函数

#define TT_RELEASE_CF_SAFELY(__REF) { if (nil != (__REF)) { CFRelease(__REF); __REF = nil; } }

判断是真机还是模拟器

#if TARGET_OS_IPHONE
    //iPhone Device
#endif

#if TARGET_IPHONE_SIMULATOR
    //iPhone Simulator
#endif

检查系统版本

//当前版本 = 版本v 
#define SYSTEM_VERSION_EQUAL_TO(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)

//当前版本 > 版本v
#define SYSTEM_VERSION_GREATER_THAN(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
//当前版本 >= 版本v
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

//当前版本 < 版本v
#define SYSTEM_VERSION_LESS_THAN(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
//当前版本 <= 版本v
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

内存

使用ARC和不使用ARC （ARC）

#if __has_feature(objc_arc)
    //compiling with ARC
#else
    // compiling without ARC
#endif

#pragma mark - common functions
#define RELEASE_SAFELY(__POINTER) { [__POINTER release]; __POINTER = nil; }

释放一个对象

#define SAFE_DELETE(P) if(P) { [P release], P = nil; }

或

#define SAFE_RELEASE(x) [x release];x=nil

图片

读取本地图片

#define LOADIMAGE(file,ext) [UIImage imageWithContentsOfFile:[NSBundle mainBundle] pathForResource:file ofType:ext］

定义UIImage对象（路径）

#define IMAGE(A) [UIImage imageWithContentsOfFile:[NSBundle mainBundle] pathForResource:A ofType:nil］

建议使用这两种宏定义，性能高于下者。

定义UIImage对象

#define ImageNamed(_pointer) [UIImage imageNamed:[UIUtil imageName:_pointer］

颜色类

rgb颜色转换（16进制 --> 10进制）

#define UIColorFromRGB(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]

带有RGBA的颜色设置（A：alpha）

#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]

获取RGB颜色

#define RGBA(r,g,b,a) [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:a]

#define RGB(r,g,b) RGBA(r,g,b,1.0f)

背景色

#define BACKGROUND_COLOR [UIColor colorWithRed:242.0/255.0 green:236.0/255.0 blue:231.0/255.0 alpha:1.0]

清除背景色

#define CLEARCOLOR [UIColor clearColor]

#pragma mark - color functions
#define RGBCOLOR(r,g,b) [UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:1]
#define RGBACOLOR(r,g,b,a) [UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:(a)]

其他

方正黑体简体字体定义

#define FONT(F) [UIFont fontWithName:@"FZHTJW--GB1-0" size:F]

定义一个API
```
#define APIURL @"http://xxxxx/"
```

登录API

#define APILogin [APIURL stringByAppendingString:@"Login"]

设置View的tag(值)属性

#define VIEWWITHTAG(_OBJECT, _TAG) [_OBJECT viewWithTag: _TAG]

程序的本地化,引用国际化的文件

#define MyLocal(x, ...) NSLocalizedString(x, nil)

GCD

#define BACK(block) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), block)

#define MAIN(block) dispatch_async(dispatch_get_main_queue(),block)

NSUserDefaults 实例化

#define USER_DEFAULT [NSUserDefaults standardUserDefaults]

由角度获取弧度

#define degreesToRadian(x) (M_PI * (x) / 180.0)

由弧度获取角度

#define radianToDegrees(radian) (radian*180.0)/(M_PI)

单例化一个类

#define SYNTHESIZE_SINGLETON_FOR_CLASS(classname) \
\
 static classname *shared##classname = nil; \
\

 + (classname *)shared##classname \
{ \

@synchronized(self) \
{ \

 if (shared##classname == nil) \
{ \

 shared##classname = ［self alloc] init]; \
} \

} \
\

 return shared##classname; \
} \
\

 + (id)allocWithZone:(NSZone *)zone \
{ \

@synchronized(self) \
{ \

 if (shared##classname == nil) \
{ \

 shared##classname = [super allocWithZone:zone]; \
 return shared##classname; \
} \
} \
\

 return nil; \
} \
\

- (id)copyWithZone:(NSZone *)zone \
{ \

 return self; \
}

#endif

后续有的话，会继续添加进来。

iPhone X的登场改变各别的尺寸！！！

#define Width_IphoneX 375   //iPhoneX 屏宽
#define height_IphoneX 812  //iPhoneX 屏高

//是否 是iPhoneX
#define isIphoneX (kScreenWidth >= 375.0f && kScreenHeight >= 812.0f && isIphone)

安全高度：

//底部 安全高度
#define Bottom_Safe_Height (isIphoneX?34:0)

//系统 手势高度
#define System_Gesture_Height (isIphoneX?13:0)

各个栏的高度：

//tabBar高度
#define TabBar_Height (49 + Bottom_Safe_Height)

//状态栏高度
#define Status_Height (isIphoneX?44:20)



//导航栏高度
#define NavBar_Height 44
