NSAttributedString 链接如何指定多种颜色？

Question

想在 AttributedString 里多个链接给予不同的颜色，如何实现？

    NSString *str = @"红色 ， 蓝色 ， 绿色";
    NSMutableAttributedString *attributeString = [[NSMutableAttributedString alloc] initWithString:str attributes:nil];

    [attributeString addAttribute:NSLinkAttributeName value:@"1" range:[str rangeOfString:@"红色"]];
    [attributeString addAttribute:NSLinkAttributeName value:@"1" range:[str rangeOfString:@"蓝色"]];
    [attributeString addAttribute:NSLinkAttributeName value:@"1" range:[str rangeOfString:@"绿色"]];

然后用 NSForegroundColorAttributeName 还是改变不了链接的颜色：

[attributeString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:[str rangeOfString:@"红色"]];

这样也不行：

[attributeString addAttributes:@{NSForegroundColorAttributeName:[UIColor redColor], NSLinkAttributeName : @"1"} range:[str rangeOfString:@"红色"]];
