// 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))
