最近项目里有物流信息的东西，有一个这样的需求就是物流信息的数据里面会包含手机号，因为使用UILabel加载的物流信息，所以就要在里面显示手机号高亮，并能拨打出去，方便用户联系相关人员，直接上代码

@property (copy, nonatomic) NSAttributedString *phoneNumber;

-(void)getPhoneNumLabel:(UILabel *)label labelStr:(NSString *)labelStr
{
    //获取字符串中的电话号码
    NSString *regulaStr = @"\\d{3,4}[- ]?\\d{7,8}";
    NSRange stringRange = NSMakeRange(0, labelStr.length);
    //正则匹配
    NSError *error;
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc]initWithString:labelStr];
    NSRegularExpression *regexps = [NSRegularExpression regularExpressionWithPattern:regulaStr options:0 error:&error];
    if (!error && regexps != nil) {
        [regexps enumerateMatchesInString:labelStr options:0 range:stringRange usingBlock:^(NSTextCheckingResult * _Nullable result, NSMatchingFlags flags, BOOL * _Nonnull stop)
 {
            NSRange phoneRange = result.range;
            //定义一个NSAttributedstring接受电话号码字符串
            self.phoneNumber = [str attributedSubstringFromRange:phoneRange];
            //添加下划线
            NSDictionary *attribtDic = @{NSUnderlineStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle]};
            [str addAttributes:attribtDic range:phoneRange];
            //设置文本中的电话号码显示为红色
            [str addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:phoneRange];
            label.attributedText = str;
            label.userInteractionEnabled = YES;
            //添加手势，可以点击号码拨打电话
            UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGesture:)];
            [label addGestureRecognizer:tap];
        }];
    }
}

实现拨打电话

//实现拨打电话的方法
-(void)tapGesture:(UITapGestureRecognizer *)sender
{
    NSString *deviceType = [UIDevice currentDevice].model;
    if([deviceType  isEqualToString:@"iPod touch"]||[deviceType  isEqualToString:@"iPad"]||[deviceType  isEqualToString:@"iPhone Simulator"])
    {
        UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"提示" message:@"您的设备不能打电话" delegate:nil cancelButtonTitle:@"好的,知道了" otherButtonTitles:nil,nil];
        [alert show];
    }
    else
    {
        //NSAttributedstring转换为NSString
        NSString *stringNum = [self.phoneNumber string];
        NSMutableString * str=[[NSMutableString alloc] initWithFormat:@"tel:%@",stringNum];
        NSString *newStr = [str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
        UIWebView * callWebview = [[UIWebView alloc] init];
        [callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newStr]]];
        [self addSubview:callWebview];
    }
}

在赋值之后愉快的调用这个方法就好了~
