iOS中常見(jiàn)正則表達(dá)式驗(yàn)證方法

發(fā)布時(shí)間：2020-09-21 19:44:16 來(lái)源：腳本之家閱讀：175 作者：六度Space 欄目：移動(dòng)開(kāi)發(fā)

在某些App應(yīng)用里面需要填寫(xiě)用戶信息（用于驗(yàn)證），有身份證、手機(jī)號(hào)、軍官證等等。下面來(lái)跟大家分享一下各自的驗(yàn)證方式。

1.驗(yàn)證手機(jī)號(hào)碼，這個(gè)是對(duì)任意輸入的一串?dāng)?shù)字做驗(yàn)證，返回一個(gè)識(shí)別結(jié)果（字符串），根據(jù)這個(gè)結(jié)果再做判斷。

//判斷手機(jī)號(hào)碼
+ (NSString *)valiMobile:(NSString *)mobile{
  if (mobile.length != 11){
    return @"手機(jī)號(hào)碼格式錯(cuò)誤";
  }else{
    /**
     * 移動(dòng)號(hào)段正則表達(dá)式
     */
    NSString *CM_NUM = @"^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$";
    /**
     * 聯(lián)通號(hào)段正則表達(dá)式
     */
    NSString *CU_NUM = @"^((13[0-2])|(145)|(15[5-6])|(176)|(18[5,6]))\\d{8}|(1709)\\d{7}$";
    /**
     * 電信號(hào)段正則表達(dá)式
     */
    NSString *CT_NUM = @"^((133)|(153)|(177)|(18[0,1,9]))\\d{8}$";
    NSPredicate *pred1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM_NUM];
    BOOL isMatch2 = [pred1 evaluateWithObject:mobile];
    NSPredicate *pred2 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU_NUM];
    BOOL isMatch3 = [pred2 evaluateWithObject:mobile];
    NSPredicate *pred3 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT_NUM];
    BOOL isMatch4 = [pred3 evaluateWithObject:mobile];
    if (isMatch2 || isMatch3 || isMatch4) {
      return nil;
    }else{
      return @"請(qǐng)輸入正確的手機(jī)號(hào)碼";
    }
  }
  return nil;
}

2.驗(yàn)證軍官證

//驗(yàn)證軍官證
- (BOOL) checkOfficerCard: (NSString *) officerCard{
  //exp:政字第00111206號(hào)
  BOOL flag;
  if (officerCard.length <= 0) {
    flag = NO;
    return flag;
  }
  NSString *regex2 = @"^([\u5357|\u5317|\u6c88|\u5170|\u6210|\u6d4e|\u5e7f|\u6d77|\u7a7a|\u53c2|\u653f|\u540e|\u88c5][\u5b57][\u7b2c]\\d{8}[\u53f7])$";
  NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
  return [identityCardPredicate evaluateWithObject:officerCard];
}

3.驗(yàn)證身份證，這個(gè)是真實(shí)身份證的驗(yàn)證方法，具有唯一性。

//精確的身份證號(hào)碼有效性檢測(cè)
- (BOOL) accurateVerifyIDCardNumber:(NSString *)value {
  value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
  int length =0;
  if (!value) {
    return NO;
  }else {
    length = (int)value.length;
    if (length !=15 && length !=18) {
      return NO;
    }
  }
  // 省份代碼
  NSArray *areasArray =@[@"11",@"12", @"13",@"14", @"15",@"21", @"22",@"23", @"31",@"32", @"33",@"34", @"35",@"36", @"37",@"41", @"42",@"43", @"44",@"45", @"46",@"50", @"51",@"52", @"53",@"54", @"61",@"62", @"63",@"64", @"65",@"71", @"81",@"82", @"91"];
  NSString *valueStart2 = [value substringToIndex:2];
  BOOL areaFlag =NO;
  for (NSString *areaCode in areasArray) {
    if ([areaCode isEqualToString:valueStart2]) {
      areaFlag =YES;
      break;
    }
  }
  if (!areaFlag) {
    return NO;
  }
  NSRegularExpression *regularExpression;
  NSUInteger numberofMatch;

  int year =0;
  switch (length) {
    case 15:
      year = [value substringWithRange:NSMakeRange(6,2)].intValue +1900;

      if (year %4 ==0 || (year %100 ==0 && year %4 ==0)) {

        regularExpression = [[NSRegularExpression alloc] initWithPattern:@"^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}$"
                                     options:NSRegularExpressionCaseInsensitive
                                      error:nil];//測(cè)試出生日期的合法性
      }else {
        regularExpression = [[NSRegularExpression alloc]initWithPattern:@"^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))[0-9]{3}$"

                                     error:nil];//測(cè)試出生日期的合法性
      }
      numberofMatch = [regularExpression numberOfMatchesInString:value
                                options:NSMatchingReportProgress
                                 range:NSMakeRange(0, value.length)];

      if(numberofMatch >0) {
        return YES;
      }else {
        return NO;
      }
    case 18:
      year = [value substringWithRange:NSMakeRange(6,4)].intValue;
      if (year %4 ==0 || (year %100 ==0 && year %4 ==0)) {

        regularExpression = [[NSRegularExpression alloc] initWithPattern:@"^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}[0-9Xx]$"

      }else {
        regularExpression = [[NSRegularExpression alloc] initWithPattern:@"^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))[0-9]{3}[0-9Xx]$"
                                     options:NSRegularExpressionCaseInsensitive
                                      error:nil];//測(cè)試出生日期的合法性
      }
      numberofMatch = [regularExpression numberOfMatchesInString:value
                                options:NSMatchingReportProgress
                                 range:NSMakeRange(0, value.length)];

      if(numberofMatch >0) {
        int S = ([value substringWithRange:NSMakeRange(0,1)].intValue + [value substringWithRange:NSMakeRange(10,1)].intValue) *7 + ([value substringWithRange:NSMakeRange(1,1)].intValue + [value substringWithRange:NSMakeRange(11,1)].intValue) *9 + ([value substringWithRange:NSMakeRange(2,1)].intValue + [value substringWithRange:NSMakeRange(12,1)].intValue) *10 + ([value substringWithRange:NSMakeRange(3,1)].intValue + [value substringWithRange:NSMakeRange(13,1)].intValue) *5 + ([value substringWithRange:NSMakeRange(4,1)].intValue + [value substringWithRange:NSMakeRange(14,1)].intValue) *8 + ([value substringWithRange:NSMakeRange(5,1)].intValue + [value substringWithRange:NSMakeRange(15,1)].intValue) *4 + ([value substringWithRange:NSMakeRange(6,1)].intValue + [value substringWithRange:NSMakeRange(16,1)].intValue) *2 + [value substringWithRange:NSMakeRange(7,1)].intValue *1 + [value substringWithRange:NSMakeRange(8,1)].intValue *6 + [value substringWithRange:NSMakeRange(9,1)].intValue *3;

      }else {

  }
}

4.郵箱的驗(yàn)證

//郵箱驗(yàn)證
- (BOOL)isEmailAddress{
  NSString *emailRegex = @"[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
  NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self matches %@",emailRegex];
  return [predicate evaluateWithObject:self];
}

5.銀行卡有效性驗(yàn)證。這里是給 NSString 寫(xiě)的分類(lèi)

/** 銀行卡號(hào)有效性問(wèn)題Luhn算法
 * 現(xiàn)行 16 位銀聯(lián)卡現(xiàn)行卡號(hào)開(kāi)頭 6 位是 622126～622925 之間的，7 到 15 位是銀行自定義的，
 * 可能是發(fā)卡分行，發(fā)卡網(wǎng)點(diǎn)，發(fā)卡序號(hào)，第 16 位是校驗(yàn)碼。
 * 16 位卡號(hào)校驗(yàn)位采用 Luhm 校驗(yàn)方法計(jì)算：
 * 1，將未帶校驗(yàn)位的 15 位卡號(hào)從右依次編號(hào) 1 到 15，位于奇數(shù)位號(hào)上的數(shù)字乘以 2
 * 2，將奇位乘積的個(gè)十位全部相加，再加上所有偶數(shù)位上的數(shù)字
 * 3，將加法和加上校驗(yàn)位能被 10 整除。
 */
- (BOOL)bankCardCheck{
  NSString * lastNum = [[self substringFromIndex:(self.length-1)] copy];//取出最后一位
  NSString * forwardNum = [[self substringToIndex:(self.length -1)] copy];//前15或18位

  NSMutableArray * forwardArr = [[NSMutableArray alloc] initWithCapacity:0];
  for (int i=0; i<forwardNum.length; i++) {
    NSString * subStr = [forwardNum substringWithRange:NSMakeRange(i, 1)];
    [forwardArr addObject:subStr];
  }

  NSMutableArray * forwardDescArr = [[NSMutableArray alloc] initWithCapacity:0];
