IOS常用宏定义

// 1.判断是否为iOS7

#define iOS7 ([[UIDevice currentDevice].systemVersion doubleValue] >= 7.0)

// 2.获得RGB颜色

#define MXColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]

// 3.自定义Log

#ifdef DEBUG

#define MXLog(...) NSLog(__VA_ARGS__)

#else

#define MXLog(...)

#endif

// 4.是否为4inch

#define fourInch ([UIScreen mainScreen].bounds.size.height == 568)
