iOS开发之十六进制颜色数据转化为UIColor对象

 1 - (UIColor *)getColor:(NSString *)hexColor
 2 {
 3     unsigned int red,green,blue;
 4     NSRange range;
 5     range.length = 2;
 6     
 7     //截取red部分
 8     range.location = 0;
 9     [[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&red];
10     
11     //截取green部分
12     range.location = 2;
13     [[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&green];
14     
15     //截取blue部分
16     range.location = 4;
17     [[NSScanner scannerWithString:[hexColor substringWithRange:range]] scanHexInt:&blue];
18     
19     return rgbColor(red, green, blue, 1.0);
