c++正则表达式验证手机号

使用正则表达式验证手机号，可以使用regex_match函数进行全文匹配。下面是一个示例的正则表达式来验证手机号码：

NSString *phoneNumber = @"^1[3456789]\\d{9}$";
BOOL isValid = [self regex_match:phoneNumber withPattern:@"^1[3456789]\\d{9}$"];

该正则表达式的含义是，手机号码以1开头，后面跟着3、＊＊＊如果需要验证其他国家或地区的手机号码，请根据对应的格式进行调整。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
