新版正则表达式代码：

{
    return YES;
}
else
{
    return NO;
}

}

下面我们简单拆分上面方法，来应对不同的需求

如果只是简单匹配是否是手机号码，并不需要上面那么多行代码，可以简单写成这样：

NSString *MOBILE = @"^1(3[0-9]|4[57]|5[0-35-9]|8[0-9]|7[0678])\d{8}$";
NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE];
return [regextestmobile evaluateWithObject:mobileNum];

如果你需要匹配是否是移动/联通/电信手机号。
判断移动手机号就是这样：

(BOOL)isChinaMobile:(NSString *)phoneNum
{
NSString *CM = @"(^{1(3[4-9]|4[7]|5[0-27-9]|7[8]|8[2-478])\d{8}$)|(}1705\d{7}$)";
NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM];
return [regextestcm evaluateWithObject:phoneNum];
}

相信细心的朋友，应该已经明白了。判断联通手机号，只要把我们的正则字符串改成上面判断联通手机号的字符串就可以了。判断哪种就改变正则表达式就可以了

ok，在这个基础上，我们还可以组合来判断具体是哪个运营商的手机号，代码如下：

(NSString *)getPhoneNumType:(NSString *)phoneNum
{
return [self isChinaMobile:phoneNum]? @"中国移动": ([self isChinaUnicom:phoneNum]? @"中国联通":([self isChinaTelecom:phoneNum]? @"中国电信": @"未知"));
}

主要方法都已公布，至于Swift或者其他语言代码块就不一一放上来了，真让我都写，我也不一定都会。。。哈哈哈，核心正则表达式，都是可以用的，拿着代入进去就ok了。

/** 银行卡号有效性问题Luhn算法

现行 16 位银联卡现行卡号开头 6 位是 622126～622925 之间的，7 到 15 位是银行自定义的，
可能是发卡分行，发卡网点，发卡序号，第 16 位是校验码。
16 位卡号校验位采用 Luhm 校验方法计算：
1，将未带校验位的 15 位卡号从右依次编号 1 到 15，位于奇数位号上的数字乘以 2
2，将奇位乘积的个十位全部相加，再加上所有偶数位上的数字
3，将加法和加上校验位能被 10 整除。
