Object-C开发常用宏定义

Object-C开发中宏会将经常用到的系统常量进行封装,方便使用:

1、获取通知中心
#define EYNotificationCenter(name, object, userInfo) [[NSNotificationCenter defaultCenter] postNotificationName:name object:object userInfo:userInfo]

2、设置 view 圆角和边框
#define EYViewBorderRadius(View, Radius, Width, Color)\
\
[View.layer setCornerRadius:(Radius)];\
[View.layer setMasksToBounds:YES];\
[View.layer setBorderWidth:(Width)];\
[View.layer setBorderColor:[Color CGColor]]

3、由角度转换弧度 由弧度转换角度
#define EYDegreesToRadian(x) (M_PI * (x) / 180.0)
#define EYRadianToDegrees(radian) (radian*180.0)/(M_PI)

4、获取图片资源
#define EYGetImage(imageName) [UIImage imageNamed:[NSString stringWithFormat:@"%@",imageName]]

5、获取当前语言
#define EYCurrentLanguage ([NSLocale preferredLanguages].firstObject)

6、判断当前项目的环境
#if __has_feature(objc_arc)
// 编译器是ARC环境
#else
// 编译器是MRC环境
[p release];
#endif

7、判断当前的iPhone设备/系统版本
//判断是否为iPhone
#define IS_IPHONE ([[[UIDevice currentDevice] model] isEqualToString:@"iPhone"])

//判断是否为iPad
#define EYiPAD ([[[UIDevice currentDevice] model] isEqualToString:@"iPad"])

//判断是否为ipod
#define EYiPOD ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])

// 判断是否为 iPhone SE
#define EYiPhoneSE [[UIScreen mainScreen] bounds].size.width == 320.0f && [[UIScreen mainScreen] bounds].size.height == 568.0f

// 判断是否为iPhone 7
#define EYiPhone7 [[UIScreen mainScreen] bounds].size.width == 375.0f && [[UIScreen mainScreen] bounds].size.height == 667.0f

// 判断是否为iPhone 7Plus
#define EYiPhone7Plus [[UIScreen mainScreen] bounds].size.width == 414.0f && [[UIScreen mainScreen] bounds].size.height == 736.0f

8、获取系统版本
#define EYSystemVersion [[UIDevice currentDevice] systemVersion]

//判断 iOS 8 或更高的系统版本
#define IOS_VERSION_8_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0)? (YES):(NO))

9、判断是真机还是模拟器
#if TARGET_OS_IPHONE
//iPhone Device
#endif

#if TARGET_IPHONE_SIMULATOR
//iPhone Simulator
#endif

10、沙盒目录文件
//获取temp
#define EYPathTemp NSTemporaryDirectory()

//获取沙盒 Document
#define EYPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]

//获取沙盒 Cache
#define EYPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]

11.字符串是否为空
#define EYStringIsEmpty(string) ([string isKindOfClass:[NSNull class]] || string.length == 0 ? YES : NO)

12.数组是否为空
#define EYArrayIsEmpty(array) ([array isKindOfClass:[NSNull class]] || array.count == 0 ? YES : NO)

13.字典是否为空
#define EYDictionaryIsEmpty(dictionary) ([dictionary isKindOfClass:[NSNull class]] || dictionary.allKeys == 0 ? YES : NO)

14.自定义Log
#ifdef DEBUG
#define EYLog(...) NSLog(@"%s 第%d行 \n %@\n\n",__func__,__LINE__,[NSString stringWithFormat:__VA_ARGS__])
#else
#define EYLog(...)

#endif

15.颜色
#define EYRGBColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]

// RGB颜色 red green blue alpha 为系统关键字，不能使用
#define EYRGBAColor(r, g, b, a) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:(a)/1.0]

随机色
#define EYRandomColor EYRGBAColor(arc4random_uniform(256), arc4random_uniform(256), arc4random_uniform(256), 1.0)

clear背景颜色
#define EYClearColor [UIColor clearColor]

16.屏幕的宽度 不要用self.view.bounds.size.width 因为view可能是Xib创建的，导致取出来的宽度不准确，需要取出当前使用设备的屏幕
#define EYScreenWidth [[UIScreen mainScreen] bounds].size.width

#define EYScreenHeight [[UIScreen mainScreen] bounds].size.height
