定期验证用户的账户密码、手机号码和

这一次js正则验证号码，我会给您带来定期验证用户账户密码、手机号码和的方法. 定期验证用户帐号密码、手机号码和有哪些注意事项？这是一个真实的案例. 让我们一起来看看

没什么废话. 让我们介绍一下如何使用正则表达式来验证用户名、密码、手机号码和. 请参考一下

//用户名
+ (BOOL) validateUserName:(NSString *)name
{
 NSString *userNameRegex = @"^[A-Za-z0-9]{3,20}+$";
 NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex];
 BOOL B = [userNamePredicate evaluateWithObject:name];
 return B;
}
//密码
+ (BOOL) validatePassword:(NSString *)passWord
{
 NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";
 NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];
 return [passWordPredicate evaluateWithObject:passWord];
}
//判断手机号码格式是否正确
+ (BOOL)valiMobile:(NSString *)mobile
{
 mobile = [mobile stringByReplacingOccurrencesOfString:@" " withString:@""];
 if (mobile.length != 11)
 {
  return NO;
 }else{
  /**
   * 移动号段正则表达式
   */
  NSString *CM_NUM = @"^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$";
  /**
   * 联通号段正则表达式
   */
  NSString *CU_NUM = @"^((13[0-2])|(145)|(15[5-6])|(176)|(18[5,6]))\\d{8}|(1709)\\d{7}$";
  /**
   * 电信号段正则表达式
   */
  NSString *CT_NUM = @"^((133)|(153)|(177)|(18[0,1,9]))\\d{8}$";
  NSPredicate *pred1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM_NUM];
  BOOL isMatch1 = [pred1 evaluateWithObject:mobile];
  NSPredicate *pred2 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU_NUM];
  BOOL isMatch2 = [pred2 evaluateWithObject:mobile];
  NSPredicate *pred3 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT_NUM];
  BOOL isMatch3 = [pred3 evaluateWithObject:mobile];
  if (isMatch1 || isMatch2 || isMatch3) {
   return YES;
  }else{
   return NO;
  }
 }
}
/**
 * 验证号码是否正确的方法
 *
 * @param IDNumber 传进号码字符串
 *
 * @return 返回YES或NO表示该号码是否符合国家标准
 */
+ (BOOL)isCorrect:(NSString *)IDNumber
{
 NSMutableArray *IDArray = [NSMutableArray array];
 // 遍历字符串,存入数组中
 if (IDNumber.length == 18) {
  for (int i = 0; i < 18; i++) {
   NSRange range = NSMakeRange(i, 1);
   NSString *subString = [IDNumber substringWithRange:range];
   [IDArray addObject:subString];
  }
 }else{
  for (int i = 0; i < 15; i++) {
   NSRange range = NSMakeRange(i, 1);
   NSString *subString = [IDNumber substringWithRange:range];
   [IDArray addObject:subString];
  }
 }
 // 系数数组
 NSArray *coefficientArray = [NSArray arrayWithObjects:@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2", nil];
 // 余数数组
 NSArray *remainderArray = [NSArray arrayWithObjects:@"1", @"0", @"X", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2", nil];
 // 每一位号码和对应系数相乘之后相加所得的和
 int sum = 0;
 if (IDNumber.length == 18) {
  for (int i = 0; i < 17; i++) {
   int coefficient = [coefficientArray[i] intValue];
   int ID = [IDArray[i] intValue];
   sum += coefficient * ID;
  }
 }else{
  for (int i = 0; i < 14; i++) {
   int coefficient = [coefficientArray[i] intValue];
   int ID = [IDArray[i] intValue];
   sum += coefficient * ID;
  }
 }
 // 这个和除以11的余数对应的数
 NSString *str = remainderArray[(sum % 11)];
 // 号码最后一位
 NSString *string;
 if (IDNumber.length == 18) {
  string = [IDNumber substringFromIndex:17];
 }else{
  string = [IDNumber substringFromIndex:14];
 }
 // 如果这个数字和最后一位相同,则符合国家标准,返回YES
 if ([str isEqualToString:string]) {
  return YES;
 } else {
  return NO;
 }
}
