调用：

在要使用判断的.m文件加上

#import "RegularJudge.h"

RegularJudge *regul= [[RegularJudge alloc]init];

if ( ![regul checkTel: self.phoneNo.text]) {

UIAlertView * aleart= [[UIAlertView alloc]initWithTitle:@"提示" message:@"请填写有效的电话号码！" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil,nil];

[aleart show];

self.phoneNo.text =@"";
