在项目中输入经纬度的时候，老大要求用正则来验证输入内容，当我还在写正则的时候，他就在把他保存的一些正则发给了我们。我简单的做了一下处理，在这里贡献给大家，正则部分 Android和iOS通用的。
Android的小伙伴直接参看RegularContansts.m文件中的内容。
以下内容按照文件来写
NSString+Regular.h
#import <Foundation/Foundation.h>
@interface NSString (Regular)
/**
* 注册用户名有效性验证支持字母、数字、下划线、汉字
* (1).(6-32位)
* (2).(不能以 _开始或结束)
* (3).(必须包含一个字母或汉字)
*/
+ (BOOL)registerWithUserName:(NSString *)userName;
/**
* 登录用户名（包含用户名或手机）有效性验证支持字母、数字、下划线、汉字
* (1).(6-32位)
* (2).(不能以 _开始和结束)
*/
+ (BOOL)loginWithUserName:(NSString *)username;
/**
* 密码有效性验证支持字母、数字、下划线
* (1).(6-32位)
* (2).(不能以 _开始和结束)
* 注意：密码在前台做验证，后台得到的是一个32位md5之后的字符串
*/
+ (BOOL)verifyWithPassWord:(NSString *)password;
/**
* 手机号码验证
* (1).以13、14、15、17、18开头
* (2).11位数字
*/
+ (BOOL)verifyWithMobile:(NSString *)mobile;
/**
* qq号码
*/
+ (BOOL)verifyWithQQNumber:(NSString *)qqNumber;
/**
* 1w位的纯数字
*/
+ (BOOL)verifyWithNumbers:(NSString *)numbers;
/**
* ip正则
*/
+ (BOOL)verifyWithIP:(NSString *)ip;
/**
* 英文字母
*/
+ (BOOL)verifyWithEnglish:(NSString *)english;
/**
* 经度： -180.0～+180.0（整数部分为0～180，必须输入1到6位小数）
*/
+ (BOOL)verifyWithLongitude:(NSString *)lng;
/**
* 纬度： -90.0～+90.0（整数部分为0～90，必须输入1到6位小数）
*/
+ (BOOL)verifyWithLatitude:(NSString *)lat;

当然，你们也可以根据自己的细节需求来进行修改。如果能帮到各位，可不可以给个小心心呢？哈哈哈哈。。。。
