iOS正则表达式

最近整理了之前用到的正则表达式，有不足之处还请大家指正哦！！

//手机号码验证

+ (BOOL) validateMobile:(NSString *)mobile {    //手机号以13， 15，18开头，八个 \d 数字字符    NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";    NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];    return [phoneTest evaluateWithObject:mobile];}

//用户名

+ (BOOL) validateUserName:(NSString *)name {    NSString *userNameRegex = @"^[A-Za-z0-9]{6,20}+$";    NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex];    BOOL B = [userNamePredicate evaluateWithObject:name];    return B;}

//密码

+ (BOOL) validatePassword:(NSString *)passWord {    NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";    NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];    return [passWordPredicate evaluateWithObject:passWord];}

//昵称

+ (BOOL) validateNickname:(NSString *)nickname {    NSString *nicknameRegex = @"^[\u4e00-\u9fa5]{4,8}$";    NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",nicknameRegex];    return [passWordPredicate evaluateWithObject:nickname];}

//身份证号

+ (BOOL) validateIdentityCard: (NSString *)identityCard {    BOOL flag;    if (identityCard.length <= 0) {        flag = NO;        return flag;    }    NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";    NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];    return [identityCardPredicate evaluateWithObject:identityCard];}

//邮箱

+ (BOOL) validateEmail:(NSString *)email {    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];    return [emailTest evaluateWithObject:email];}

//车牌号验证

+ (BOOL) validateCarNo:(NSString *)carNo {    NSString *carRegex = @"^[\u4e00-\u9fa5]{1}[a-zA-Z]{1}[a-zA-Z_0-9]{4}[a-zA-Z_0-9_\u4e00-\u9fa5]$";    NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",carRegex];    NSLog(@"carTest is %@",carTest);    return [carTest evaluateWithObject:carNo];}

//车型

+ (BOOL) validateCarType:(NSString *)CarType {    NSString *CarTypeRegex = @"^[\u4E00-\u9FFF]+$";    NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",CarTypeRegex];    return [carTest evaluateWithObject:CarType];}
