NSArray *resultStr = [regex matchesInString:string options:kNilOptions range:NSRangeMake(0,string.length)];
for (NSTextCheckingResult *at in resultStr){
        if (at.range.location == NSNotFound && at.range.length <= 1){
            continue;
        }
        // 给url添加下划线
        NSDictionary *attribtDic = @{NSUnderlineStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle]};
        [attrStrings setYy_attributes:attribtDic];
