iOS正则表达式之验证问题总结

1.验证输入都是数字：

// 判断仅输入数字：

+ (BOOL)isInputShouldAlphaNum: (NSString *)inputStr
{
    NSString *regex =@"[0-9]*";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex];
    if ([pred evaluateWithObject:inputStr]) {
        return YES;
    }
    return NO;
}

2.验证输入手机号：

+ (BOOL) IsPhoneNumber:(NSString *)number
{
    NSString *phoneRegex1=@"1[34578]([0-9]){9}";
    NSPredicate *phoneTest1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex1];
    return  [phoneTest1 evaluateWithObject:number];
}

3.邮箱验证：

// 邮箱验证
- (BOOL)isValidateEmail:(NSString *)email {
    
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
    return [emailTest evaluateWithObject:email];
}

4.身份证验证：

+ (BOOL) IsIdentityCard:(NSString *)IDCardNumber
{
    if (IDCardNumber.length <= 0) {
        return NO;
    }
    NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";
    NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
    return [identityCardPredicate evaluateWithObject:IDCardNumber];
}

5.座机号码验证：

// 座机验证
- (BOOL)isValidateTel: (NSString *)tel {
    
    //验证输入的固话中不带 "-"符号
    NSString * strNum = @"^(0[0-9]{2,3})?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$|(^(13[0-9]|15[0|3|6|7|8|9]|18[8|9])\\d{8}$)";
    
    //验证输入的固话中带 "-"符号
    //NSString * strNum = @"^(0[0-9]{2,3}-)?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$|(^(13[0-9]|15[0|3|6|7|8|9]|18[8|9])\\d{8}$)";
    
    NSPredicate *checktest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", strNum];
    return [checktest evaluateWithObject:tel];
}

6.银行卡验证：

+ (BOOL) IsBankCard:(NSString *)cardNumber
{
    if(cardNumber.length==0)
    {
        return NO;
    }
    NSString *digitsOnly = @"";
    char c;
    for (int i = 0; i < cardNumber.length; i++)
    {
        c = [cardNumber characterAtIndex:i];
        if (isdigit(c))
        {
            digitsOnly =[digitsOnly stringByAppendingFormat:@"%c",c];
        }
    }
    int sum = 0;
    int digit = 0;
    int addend = 0;
    BOOL timesTwo = false;
    for (NSInteger i = digitsOnly.length - 1; i >= 0; i--)
    {
        digit = [digitsOnly characterAtIndex:i] - '0';
        if (timesTwo)
        {
            addend = digit * 2;
            if (addend > 9) {
                addend -= 9;
            }
        }
        else {
            addend = digit;
        }
        sum += addend;
        timesTwo = !timesTwo;
    }
    int modulus = sum % 10;
    return modulus == 0;
}
