宏定义可以在我们平时的开发中帮助我们更简洁有效的进行编程，以下是我工作中遇到和搜集整理的一些宏定义：

关于UI设置

/*UI颜色的快捷设置/

#define kHEXCOLOR(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]

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

//随即颜色

//设置RGB颜色/设置RGBA颜色
#define kRGBColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]

// clear背景颜色
#define LRClearColor [UIColor clearColor]

#define RGBA(r, g, b, a) [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:a]   //返回一个RGBA格式的UIColor对象
#define RGB(r, g, b) RGBA(r, g, b, 1.0f) // 返回一个RGB格式的UIColor对象
