iOS开发实用技巧—身份证的正则校验
说明：
一、规则
二、代码示例：
对于这种需要在很多地方都用到的代码，可以使用一个工具类或者是分类来写。这里把校验的代码写在了一个工具类中。
VerifyRegexTool.h文件代码：
1 #import <Foundation/Foundation.h> 2 3 @interface VerifyRegexTool : NSObject 4 5 + (BOOL)verifyIsNotEmpty:(NSString *)str; //验证是否不为空 6 7 + (BOOL)verifyText:(NSString *)text withRegex:(NSString *)regex; //正则验证 8 9 + (BOOL)verifyIDCardNumber:(NSString *)value; //验证身份证 10 11 + (BOOL)verifyCardNumberWithSoldier:(NSString *)value; //验证军官证或警官证 12 13 + (BOOL)verifyIDCardHadAdult:(NSString *)card; //验证身份证是否成年且小于100岁****这个方法中不做身份证校验，请确保传入的是正确身份证 14 15 + (BOOL)verifyIDCardMoreThanPointDate:(NSString *)card withNumber:(NSInteger)number withAddTimeInterval:(NSTimeInterval)interval withDateType:(DateType)dateType; //验证身份证加上指定天数是否大于指定number的类型 16 17 + (BOOL)verifyIDCardLessThanPointDate:(NSString *)card withNumber:(NSInteger)number withAddTimeInterval:(NSTimeInterval)interval withDateType:(DateType)dateType; //验证身份证是否小于指定number的类型 18 19 20 + (NSString *)getIDCardBirthday:(NSString *)card; //得到身份证的生日****这个方法中不做身份证校验，请确保传入的是正确身份证 21 + (NSInteger)getIDCardSex:(NSString *)card; //得到身份证的性别（1男0女）****这个方法中不做身份证校验，请确保传入的是正确身份证 22 23 @end
VerifyRegexTool.m文件代码：
1 #import "VerifyRegexTool.h" 2 3 @implementation VerifyRegexTool 4 5 //验证是否不为空 6 + (BOOL)verifyIsNotEmpty:(NSString *)str 7 { 8 if (!str) return NO; 9 10 str = [str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

身份证校验调用示例：
1 if (![VerifyRegexTool verifyIDCardNumber:self.IdentityCardNOTextfield.text]) { //验证身份证是否真实 2 [self showMessageHUD:@"请输入正确的身份证号码！" withTimeInterval:kShowMessageTime]; 3 return; 4 }
