改变指定位置字符的颜色，代码如下：

NSString *descStr = @"楼主";
    NSString *nickStr = [NSString stringWithFormat:@"小仙女%@",descStr];
    NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc]initWithString:descStr];
    [attrStr addAttribute:NSForegroundColorAttributeName value:MainColor range:[nickStr rangeOfString:descStr]];
    self.TopUserInfoV.titleLabs.attributedText = attrStr;

如下图红框：
