因为要做物流信息展示，展示相关快递信息等，可能会有电话、座机号等联系方式，要求可点击并能打电话。
开始网上找的一个，如下：

-(void)distinguishPhoneNumLabel:(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];
    
    
    NSInteger matches = [regexps numberOfMatchesInString:labelStr options:0 range:NSMakeRange(0, labelStr.length)];
    
    
    if (matches > 0) {
        
       
    }else
    {
        label.text = labelStr;
        
        return;
    }
    
    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
            _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黄色
            //            [str addAttribute:NSForegroundColorAttributeName value:[LFWImage colorWithHexString:@"FF8200"] range:phoneRange];
            
            [str addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHexString:@"#eb2323"] range:phoneRange];
            
             [str addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:13] 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];
            
        }];
    }
    
    
    
}

这个可以实现文字中有一个电话号码，并且只能匹配手机号。

如果有多个手机号，或者参杂座机号就会有问题，只能匹配到一个手机号。

然后，改用以下方法便可以解决以上问题。

☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️

首先添加头文件 #import "YYText.h"， #import "NSString+phone.h"，添加宏 #define PHONEREGULAR @"\\d{3,4}[- ]?\\d{7,8}"//匹配10到12位连续数字，或者带连字符/空格的固话号，空格和连字符可以省略。

创建分类NSString+phone.h，添加方法
+ (BOOL)isMobilePhoneOrtelePhone:(NSString *)mobileNum;
用于验证是否手机号或者固话。

+ (BOOL)isMobilePhoneOrtelePhone:(NSString *)mobileNum {
    if (mobileNum==nil || mobileNum.length ==0) {
        return NO;
    }
    /**

    NSString * MOBILE = @"^((13)|(14)|(15)|(17)|(18))\\d{9}$";// @"^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$";
    /**

    NSString * CM = @"^1(34[0-8]|(3[5-9]|5[017-9]|8[23478])\\d)\\d{7}$";
    /**

    NSString * PHS = @"^((0\\d{2,3}-?)\\d{7,8}(-\\d{2,5})?)$";// @"^0(10|2[0-5789]-|\\d{3})\\d{7,8}$";
    NSString *GH = @"^400-([0-9]){1}([0-9-]{7})$";
    
    NSPredicate *regextestPHS = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", PHS];
    NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE];
    NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM];
    NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU];
    NSPredicate *regextestct = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT];
    NSPredicate *regextestGH = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", GH];
    
    if (([regextestmobile evaluateWithObject:mobileNum] == YES)
        || ([regextestcm evaluateWithObject:mobileNum] == YES)
        || ([regextestct evaluateWithObject:mobileNum] == YES)
        || ([regextestcu evaluateWithObject:mobileNum] == YES)
        || ([regextestPHS evaluateWithObject:mobileNum]==YES)
        || ([regextestGH evaluateWithObject:mobileNum] == YES)) {
        return YES;
    }
    else{
        return NO;
    }
}

重点来了，创建label，进行赋值、匹配：

- (void)reloadDataWithModel:(YYOderExpressVo*)model {
    
    
    for (UIView *temp in self.subviews) {
        
        if ([temp isKindOfClass:[YYLabel class]]) {
            [temp removeFromSuperview];
        }
    }
   
    YYLabel * label = [[YYLabel alloc]initWithFrame:CGRectMake(_detailLabel.frame.origin.x, _detailLabel.frame.origin.y, SCREEN_WIDTH-61, _detailHeightConstant.constant)];
    label.numberOfLines = 0;
    
    [self addSubview:label];
    
    NSRange stringRange = NSMakeRange(0, model.message.length);
    //正则匹配
    NSError *error;
    NSRegularExpression *regexps = [NSRegularExpression regularExpressionWithPattern:PHONEREGULAR options:0 error:&error];
    // 转为富文本
    NSMutableAttributedString *dsc = [[NSMutableAttributedString alloc]initWithString:model.message];
    // NSFontAttributeName
    [dsc addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:13] range:NSMakeRange(0, model.message.length)];

    [dsc addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithHexString:@"#999999"] range:NSMakeRange(0, model.message.length)];
    
    if (!error && regexps != nil) {
        [regexps enumerateMatchesInString:model.message options:0 range:stringRange usingBlock:^(NSTextCheckingResult * _Nullable result, NSMatchingFlags flags, BOOL * _Nonnull stop) {
            //可能为电话号码的字符串及其所在位置
            NSMutableAttributedString *actionString = [[NSMutableAttributedString alloc]initWithString:[NSString stringWithFormat:@"%@",[model.message substringWithRange:result.range]]];
            NSRange phoneRange = result.range;
            
            
            NSDictionary *attribtDic = @{NSUnderlineStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle]};
            [dsc addAttributes:attribtDic range:phoneRange];
            
            //这里需要判断是否是电话号码，并添加链接
            if ([NSString isMobilePhoneOrtelePhone:actionString.string]) {
                [dsc yy_setTextHighlightRange:phoneRange color:[UIColor colorWithHexString:@"#eb2323"] backgroundColor:[UIColor whiteColor] tapAction:^(UIView * _Nonnull containerView, NSAttributedString * _Nonnull text, NSRange range, CGRect rect) {
                    [self callPhoneThree:actionString.string];
                }];
                
            }
        }];
    }
    
    label.attributedText = dsc;
    
}

下面是打电话方法，打电话也有很多种方式，此方法可以打完电话返回当前应用。

- (void)callPhoneThree:(NSString *)phoneNum{
 
    NSLog(@"拨打电话：--》%@",phoneNum);
    
    NSString *stringNum = phoneNum;
    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 getCurrentVC].view addSubview:callWebview];
    
}

基本结束咯，补充点就是计算 label富文本高度咯。
为了方便，一起贴出来

#pragma mark 计算高度
- (CGFloat )calculateLabelHeightWithText:(NSString *)text lineSpace:(NSInteger )lineSpace fontName:(UIFont *)fontName size:(CGSize )size label:(UILabel *)label
{
    CGFloat height = 0;
    if (text.length > 0) {
        // 计算内容高度,判断显示几行
        NSString *firstWord = [text substringToIndex:1];
        CGFloat oneRowHeight = [firstWord sizeWithAttributes:@{NSFontAttributeName:fontName}].height;
        NSDictionary *attributes = @{NSFontAttributeName:fontName};
        CGSize textSize = [text boundingRectWithSize:size options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading attributes:attributes context:nil].size;
        CGFloat rows = textSize.height / oneRowHeight;
        if (rows == 1) {
            lineSpace = 0;
            height = oneRowHeight;
        } else if (rows > 1) {
            height = (oneRowHeight + lineSpace) * rows;
        }
        
    }
    return height;
}
