【进阶篇】iOS常用的OC宏定义
备忘一下iOS常用的一些宏定义，开发效率Up~
整理一下开发中常用的宏定义，正所谓工欲善其事必先利其器，没有一些方便好用的东西，就能让编码变得更加高效~~~
//获取屏幕 宽度、高度 #define DV_W ([UIScreen mainScreen].bounds.size.width) #define DV_H ([UIScreen mainScreen].bounds.size.height) //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]) //判断是否 Retina屏、设备是否%fhone 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) //判断设备的操做系统是不是ios7 #define IOS7 ([[[UIDevice currentDevice].systemVersion doubleValue] >= 7.0] //判断设备的操做系统是不是ios8 #define IOS8 ([[[UIDevice currentDevice].systemVersion doubleValue] >= 8.0] //判断设备的操做系统是不是ios9 #define IOS9 ([[[UIDevice currentDevice].systemVersion doubleValue] >= 9.0] //判断当前设备是不是iPhone4或者4s #define IPHONE4S (([[UIScreen mainScreen] bounds].size.height)==480) //判断当前设备是不是iPhone5 #define IPHONE5 (([[UIScreen mainScreen] bounds].size.height)==568) //判断当前设备是不是iPhone6 #define IPHONE6 (([[UIScreen mainScreen] bounds].size.height)==667) //判断当前设备是不是iPhone6Plus #define IPHONE6_PLUS (([[UIScreen mainScreen] bounds].size.height)>=736) //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) //判断是真机还是模拟器 #if TARGET_OS_IPHONE //iPhone Device #endif #if TARGET_IPHONE_SIMULATOR //iPhone Simulator #endif //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] // 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) #define THE_THEME_COLORA(a) RGBA(6,187,106,a) //方正黑体简体字体定义 #define FONT(F) [UIFont fontWithName:@"FZHTJW--GB1-0" size:F] //G－C－D #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) //由角度获取弧度 有弧度获取角度 #define degreesToRadian(x) (M_PI * (x) / 180.0) #define radianToDegrees(radian) (radian*180.0)/(M_PI) //打印当前方法的名称 #define ITTDPRINTMETHODNAME() ITTDPRINT(@"%s", __PRETTY_FUNCTION__)再来个GCD的//G－C－D #define BACK(block) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), block) //G-C-D主线程 #define MAIN(block) dispatch_async(dispatch_get_main_queue(),block) //延迟GCD时间 #define DisTime(time) dispatch_time(DISPATCH_TIME_NOW, time * NSEC_PER_SEC) //延迟GCD #define DisBACK(disTime,block) dispatch_after(disTime, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){dispatch_async(dispatch_get_main_queue(), block);}); ```延迟时间的用法如下//GCD延迟0.5秒执行执行 DisBACK(DisTime(0.5f),^ { //这里的代码延迟在主线程中执行 });引用楼下大神的回复再加一段：#ifdef DEBUG #define HLog(...) NSLog(__VA_ARGS__) #else #define HLog(...) #endif 用16进制的方式获取颜色： //RGB Color macro #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] //RGB color macro with alpha #define UIColorFromRGBWithAlpha(rgbValue,a) [UIColor \ colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \ green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \ blue:((float)(rgbValue & 0xFF))/255.0 alpha:a]
是不是感觉有了这些东西后，效率变得更高了~~~
