iOS 常用的正则表达式总结<待更新>

1.手机号11位

//中国移动

NSString * MOBILE = @"^1([3-9][0-9]|5[0-35-9]|8[025-9])\\d{8}$";

//中国联通

NSString * CM = @"^1([3-8][0-8]|(3[5-9]|5[017-9]|8[278])\\d)\\d{7}$";

//中国电信

//大陆地区固话及小灵通

NSString * CT = @"^1((33|53|8[09])[0-9]|349)\\d{7}$";

2.固定电话

//验证输入的固话中不带 "-"符号

NSString * strNum = @"^(0[0-9]{2,3})?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$|(^(13[0-9]|15[0|3|6|7|8|9]|18[8|9])\\d{8}$)";

//验证输入的固话中带 "-"符号

NSString * strNum = @"^(0[0-9]{2,3}-)?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$|(^(13[0-9]|15[0|3|6|7|8|9]|18[8|9])\\d{8}$)";

3.社会信用代码

NSString *scN = @"^([0-9ABCDEFGHJKLMNPQRTUWXY]{2})([0-9]{6})([0-9ABCDEFGHJKLMNPQRTUWXY]{9})([0-9Y])$";

4.匹配中文字符

NSString *string = @"[\u4e00-\u9fa5]";

5.匹配双字节字符(包括汉字)

NSString *string = @"[^\x00-\xff]";

11.匹配18位身份证号

NSString *string = @"^(\d{6})(\d{4})(\d{2})(\d{2})(\d{3})([0-9]|X)$";

12.匹配日期(年-月-日)格式

NSString *string = @"([0-9]{3}[1-9]|[0-9]{2}[1-9][0-9]{1}|[0-9]{1}[1-9][0-9]{2}|[1-9][0-9]{3})-(((0[13578]|1[02])-(0[1-9]|[12][0-9]|3[01]))|((0[469]|11)-(0[1-9]|[12][0-9]|30))|(02-(0[1-9]|[1][0-9]|2[0-8])))";

13.匹配整数

NSString *string = @"^[1-9]\d*$”;

14.匹配负数

NSString *string = @"^-[1-9]\d*$";

15.除了特殊字符

NSString *str =@"^[A-Za-z0-9\\u4e00-\u9fa5]+$";

16.长度大于6位后再接着判断是否同时包含数字和大小写字母

NSString * regex =@"^(?![0-9]+$)(?![a-zA-Z]+$)[0-9A-Za-z]{6,18}$";

17.车型

NSString *regex2 = @"^[\\u4E00-\\u9FFF]+$";

18.车牌号

NSString *carRegex = @"^[\\u4e00-\\u9fff]{1}[a-zA-Z]{1}[-][a-zA-Z_0-9]{4}[a-zA-Z_0-9_\\u4e00-\\u9fff]$";//其中\\u4e00-\\u9fa5表示unicode编码中汉字已编码部分，\\u9fa5-\\u9fff是保留部分，将来可能会添加

19.IP地址有效性

NSString *regex = [NSStringstringWithFormat:@"^(\\\\d{1,3})\\\\.(\\\\d{1,3})\\\\.(\\\\d{1,3})\\\\.(\\\\d{1,3})$"];

20.Mac地址

NSString * macAddRegex = @"([A-Fa-f\\\\d]{2}:){5}[A-Fa-f\\\\d]{2}";

NSString *taxNoRegex = @"[0-9]\\\\d{13}([0-9]|X)$";

22.身份证号验证

NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";

举例用法：+ (BOOL)isMobileNumber:(NSString *)telephoneNum{    //中国移动    NSString * MOBILE =@"^1([3-9][0-9]|5[0-35-9]|8[025-9])\\d{8}$";    //中国联通    NSString * CM = @"^1([3-8][0-8]|(3[5-9]|5[017-9]|8[278])\\d)\\d{7}$";    //中国电信    NSString * CU = @"^1([3-8][0-2]|5[256]|8[56])\\d{8}$";    //大陆地区固话及小灵通// NSString * CT = @"^1((33|53|8[09])[0-9]|349)\\d{7}$";        NSPredicate *regextestmobile = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", MOBILE];    NSPredicate *regextestcm = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", CM];    NSPredicate *regextestcu = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", CU];        if ((([regextestmobileevaluateWithObject:telephoneNum] == YES) || ([regextestcm evaluateWithObject:telephoneNum] ==YES) || ([regextestcu evaluateWithObject:telephoneNum] ==YES))&&telephoneNum.length ==11) {        return YES;    } else {        return NO;    }}
