iOS开发之UIColor－RGB

//  16 进制色值转换     使用方法 ZXColorFromRGB(0xffffff);

#define ZXColorFromRGB(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 色值    

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

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

// RGB  随机色  

#define ZXRandomColor QNColor(arc4random_uniform(256), arc4random_uniform(256), arc4random_uniform(256))
