2. 18位身份证格式和合法性验证

+(BOOL)checkUserID:(NSString *)userID
{
    //长度不为18的都排除掉
    if (userID.length!=18) {
        return NO;
    }

    NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
    BOOL flag = [identityCardPredicate evaluateWithObject:userID];

    if (!flag) {
        return flag;    //格式错误
    }else {
        //格式正确在判断是否合法

        //将前17位加权因子保存在数组里
        NSArray * idCardWiArray = @[@"7", @"9", @"10", @"5", @"8", @"4", @"2", @"1", @"6", @"3", @"7", @"9", @"10", @"5", @"8", @"4", @"2"];

        //这是除以11后，可能产生的11位余数、验证码，也保存成数组
        NSArray * idCardYArray = @[@"1", @"0", @"10", @"9", @"8", @"7", @"6", @"5", @"4", @"3", @"2"];

        //用来保存前17位各自乖以加权因子后的总和
        NSInteger idCardWiSum = 0;
        for(int i = 0;i < 17;i++)
        {
            NSInteger subStrIndex = [[userID substringWithRange:NSMakeRange(i, 1)] integerValue];
            NSInteger idCardWiIndex = [[idCardWiArray objectAtIndex:i] integerValue];

            idCardWiSum+= subStrIndex * idCardWiIndex;

        }

        //计算出校验码所在数组的位置
        NSInteger idCardMod=idCardWiSum%11;

        //得到最后一位身份证号码
        NSString * idCardLast= [userID substringWithRange:NSMakeRange(17, 1)];

        //如果等于2，则说明校验码是10，身份证号码最后一位应该是X
        if(idCardMod==2)
        {

                return NO;
            }
        }
    }
}

3. 车牌号格式校验(粤A8888澳)

+(BOOL)checkCarID:(NSString *)carID;
{
    if (carID.length!=7) {
        return NO;
    }
    NSString *carRegex = @"^[\u4e00-\u9fa5]{1}[a-hj-zA-HJ-Z]{1}[a-hj-zA-HJ-Z_0-9]{4}[a-hj-zA-HJ-Z_0-9_\u4e00-\u9fa5]$";
    NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",carRegex];
    return [carTest evaluateWithObject:carID];

    return YES;
}

4. 6~16位数字/字母/下划线组成的密码格式校验

#pragma mark    核对密码格式,6~16位数字/字母/下划线
+(BOOL)checkPsw:(NSString *)pswStr
{
    NSString * pattern  =   @"^[A-Za-z0-9_]{6,16}$";

    NSPredicate * pred  =   [NSPredicate predicateWithFormat:@"SELF MATCHES %@",pattern];
    return [pred evaluateWithObject:pswStr];
}

5. 判断字符串是否全为[(数字)OR(数字|字母)OR(字母)OR(汉字)]

+(BOOL)isAllNumber:(NSString *)string
{
    NSString *condition = @"^[0-9]*$";//是否都是数字
//    NSString *condition = @"^[A-Za-z]+$";//是否都是字母
//    NSString *condition = @"^[A-Za-z0-9]+$";//是否都是字母和数字{6,16}
//    NSString *condition = @"^[A-Za-z0-9]{6,16}$";//是否都是字母和数字且长度在[6,16]
//    NSString *condition = @"^[\u4e00-\u9fa5]{0,}$";//只能输入汉字
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES%@",condition];
    return [predicate evaluateWithObject:string];
}

6. 银行卡格式验证

//银行卡验证
+(BOOL)isBankCard:(NSString *)bankCard
{
    if (bankCard.length < 16) {
        return NO;
    }
    NSInteger oddsum = 0;     //奇数求和
    NSInteger evensum = 0;    //偶数求和
    NSInteger allsum = 0;
    NSInteger cardNoLength = (NSInteger)[bankCard length];
    // 取了最后一位数
    NSInteger lastNum = [[bankCard substringFromIndex:cardNoLength-1] intValue];
    //测试的是除了最后一位数外的其他数字
    bankCard = [bankCard substringToIndex:cardNoLength - 1];
    for (NSInteger i = cardNoLength -1 ; i>=1;i--) {
        NSString *tmpString = [bankCard substringWithRange:NSMakeRange(i-1, 1)];
        NSInteger tmpVal = [tmpString integerValue];
        if (cardNoLength % 2 ==1 ) {//卡号位数为奇数
            if((i % 2) == 0){//偶数位置
                tmpVal *= 2;
                if(tmpVal>=10)
                    tmpVal -= 9;
                evensum += tmpVal;
            }else{//奇数位置
                oddsum += tmpVal;
            }
        }else{
            if((i % 2) == 1){
                tmpVal *= 2;
                if(tmpVal>=10)
                    tmpVal -= 9;
                evensum += tmpVal;
            }else{
                oddsum += tmpVal;
            }
        }
    }

    allsum = oddsum + evensum;
    allsum += lastNum;
    if((allsum % 10) == 0)
        return YES;
    else
        return NO;
}

7. 邮箱格式验证

//验证邮箱地址
+(BOOL)isEmail:(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];
}
