下面我們簡單拆分上面方法，來應對不同的需求

如果只是簡單匹配是否是手機號碼，并不需要上面那么多行代碼，可以簡單寫成這樣：

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動/聯通/電信手機號。
判斷移動手機號就是這樣：

(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];
}

相信細心的朋友，應該已經明白了。判斷聯通手機號，只要把我們的正則字符串改成上面判斷聯通手機號的字符串就可以了。判斷哪種就改變正則表達式就可以了

ok，在這個基礎上，我們還可以組合來判斷具體是哪個運營商的手機號，代碼如下：

(NSString *)getPhoneNumType:(NSString *)phoneNum
{
return [self isChinaMobile:phoneNum]? @"中國移動": ([self isChinaUnicom:phoneNum]? @"中國聯通":([self isChinaTelecom:phoneNum]? @"中國電信": @"未知"));
}

主要方法都已公布，至于Swift或者其他語言代碼塊就不一一放上來了，真讓我都寫，我也不一定都會。。。哈哈哈，核心正則表達式，都是可以用的，拿著代入進去就ok了。
