颜色值, 设置color

#define FUIColorFromRGB(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]

//假如颜色值是 #f9f9f9 使用方法如下

 NSString * colorString = [@"#f9f9f9" stringByReplacingOccurrencesOfString:@"#" withString:@"0x"];;

 unsigned long color = strtoul([colorString UTF8String],0,0);

backVieww.backgroundColor = FUIColorFromRGB(color);
