##将iOS开发中常用的宏定义整理如下，仅包含Objective-C。
而对于Swift，不能使用宏，则可以定义全局函数或者extension。请参考博客iOS — 总结Swift中常用的全局函数和extension（持续更新中）。

// App
#define APP_VERSION [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]


// System Version
#define SYSTEM_VERSION ([[[UIDevice currentDevice] systemVersion] floatValue])
#define SYSTEM_VERSION_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_HIGHER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_EQUAL_TO_OR_HIGHER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LOWER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_EQUAL_TO_OR_LOWER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)


// Color
#define RGB(r,g,b) [UIColor colorWithRed:r / 255.f green:g / 255.f blue:b / 255.f alpha:1.f]
#define RGBA(r,g,b,a) [UIColor colorWithRed:r / 255.f green:g / 255.f blue:b / 255.f alpha:a]
#define RGB_HEX(hex) RGBA((float)((hex & 0xFF0000) >> 16),(float)((hex & 0xFF00) >> 8),(float)(hex & 0xFF),1.f)
#define RGBA_HEX(hex,a) RGBA((float)((hex & 0xFF0000) >> 16),(float)((hex & 0xFF00) >> 8),(float)(hex & 0xFF),a)

#define COLOR_LIGHT_BLUE RGB_HEX(0x7f8b97)
#define COLOR_DEEP_BLUE RGB_HEX(0x00b3d6)


// Language
#define CURRENT_LANGUAGE ([[NSLocale preferredLanguages] objectAtIndex:0])
#define IS_LANGUAGE(l) [CURRENT_LANGUAGE hasPrefix:l]
#define IS_LANGUAGE_EN IS_LANGUAGE(@"en")


// Font
#define FONT_SOFIA_MEDIUM(s) [UIFont fontWithName:@"SofiaProSoft-Medium" size:s]
#define FONT_SOFIA_SOFT(s) [UIFont fontWithName:@"SofiaProSoft" size:s]


// Screen
#define SCREEN_SIZE [[UIScreen mainScreen] bounds].size
#define SCREEN_WIDTH [[UIScreen mainScreen] bounds].size.width
#define SCREEN_HEIGHT [[UIScreen mainScreen] bounds].size.height


// GCD
#define GCD_GLOBAL(block) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), block)
#define GCD_MAIN(block
