网上对IOS的宏定义比较多，我总结了一些最常用的宏，后续还会继续补上。 1.首次启动判断： #define First_Launched @"firstLaunch"2.ios7系统判断： #define IsIOS7 ([[[UIDevice currentDevice] systemVersion] floatValue] >=7.0 ? YES : NO)3.判断是否Retina屏、是否IPhone5、是否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)  4.加载图片宏： #define LOADIMAGE(file,type) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:type]] 5.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] 6.设置颜色RGB#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]  7.去除"-(id)performSelector:(SEL)aSelector withObject:(id)object;"的警告#define SuppressPerformSelectorLeakWarning(Stuff) /do { /_Pragma("clang diagnostic push") /_Pragma("clang diagnostic ignored /"-Warc-performSelector-leaks/"") /Stuff; /_Pragma("clang diagnostic pop") /} while (0)
