iOSでよくある正規表現の検証方法
アプリによってはユーザー情報(検証用)を記入する必要があります。身分証、携帯番号、士官証などがあります。それぞれの検証方法を共有します。
1.携帯番号を確認して、これは任意に入力した数字を検証し、識別結果(文字列)を返して、この結果に基づいて判断します。

//
+ (NSString *)valiMobile:(NSString *)mobile{
if (mobile.length != 11){
return @" ";
}else{
/**
*
*/
NSString *CM_NUM = @"^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$";
/**
*
*/
NSString *CU_NUM = @"^((13[0-2])|(145)|(15[5-6])|(176)|(18[5,6]))\\d{8}|(1709)\\d{7}$";
/**
*
*/
NSString *CT_NUM = @"^((133)|(153)|(177)|(18[0,1,9]))\\d{8}$";
NSPredicate *pred1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM_NUM];
BOOL isMatch1 = [pred1 evaluateWithObject:mobile];
NSPredicate *pred2 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU_NUM];
BOOL isMatch2 = [pred2 evaluateWithObject:mobile];
NSPredicate *pred3 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT_NUM];
BOOL isMatch3 = [pred3 evaluateWithObject:mobile];
if (isMatch1 || isMatch2 || isMatch3) {
return nil;
}else{
return @" ";
}
}
return nil;
}
2.将校証の検証
//
- (BOOL) checkOfficerCard: (NSString *) officerCard{
//exp: 00111206
BOOL flag;
if (officerCard.length <= 0) {
flag = NO;
return flag;
}
NSString *regex2 = @"^([\u5357|\u5317|\u6c88|\u5170|\u6210|\u6d4e|\u5e7f|\u6d77|\u7a7a|\u53c2|\u653f|\u540e|\u88c5][\u5b57][\u7b2c]\\d{8}[\u53f7])$";
NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];
return [identityCardPredicate evaluateWithObject:officerCard];
}
3.身分証を検証して、これは本当の身分証の検証方法で、一意性を持っています。
//
- (BOOL) accurateVerifyIDCardNumber:(NSString *)value {
value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
int length =0;
if (!value) {
return NO;
}else {
length = (int)value.length;
if (length !=15 && length !=18) {
return NO;
}
}
//
NSArray *areasArray =@[@"11",@"12", @"13",@"14", @"15",@"21", @"22",@"23", @"31",@"32", @"33",@"34", @"35",@"36", @"37",@"41", @"42",@"43", @"44",@"45", @"46",@"50", @"51",@"52", @"53",@"54", @"61",@"62", @"63",@"64", @"65",@"71", @"81",@"82", @"91"];
NSString *valueStart2 = [value substringToIndex:2];
BOOL areaFlag =NO;
for (NSString *areaCode in areasArray) {
if ([areaCode isEqualToString:valueStart2]) {
areaFlag =YES;
break;
}
}
if (!areaFlag) {
return NO;
}
NSRegularExpression *regularExpression;
NSUInteger numberofMatch;
int year =0;
switch (length) {
case 15:
year = [value substringWithRange:NSMakeRange(6,2)].intValue +1900;
if (year %4 ==0 || (year %100 ==0 && year %4 ==0)) {
regularExpression = [[NSRegularExpression alloc] initWithPattern:@"^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}$"

error:nil];//
}else {

options:NSRegularExpressionCaseInsensitive
error:nil];//
}
numberofMatch = [regularExpression numberOfMatchesInString:value
options:NSMatchingReportProgress
range:NSMakeRange(0, value.length)];
if(numberofMatch >0) {
return YES;
}else {
return NO;
}
case 18:
year = [value substringWithRange:NSMakeRange(6,4)].intValue;
if (year %4 ==0 || (year %100 ==0 && year %4 ==0)) {
regularExpression = [[NSRegularExpression alloc] initWithPattern:@"^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}[0-9Xx]$"
options:NSRegularExpressionCaseInsensitive
error:nil];//
}else {

options:NSRegularExpressionCaseInsensitive
error:nil];//
}
numberofMatch = [regularExpression numberOfMatchesInString:value
options:NSMatchingReportProgress
range:NSMakeRange(0, value.length)];
if(numberofMatch >0) {
int S = ([value substringWithRange:NSMakeRange(0,1)].intValue + [value substringWithRange:NSMakeRange(10,1)].intValue) *7 + ([value substringWithRange:NSMakeRange(1,1)].intValue + [value substringWithRange:NSMakeRange(11,1)].intValue) *9 + ([value substringWithRange:NSMakeRange(2,1)].intValue + [value substringWithRange:NSMakeRange(12,1)].intValue) *10 + ([value substringWithRange:NSMakeRange(3,1)].intValue + [value substringWithRange:NSMakeRange(13,1)].intValue) *5 + ([value substringWithRange:NSMakeRange(4,1)].intValue + [value substringWithRange:NSMakeRange(14,1)].intValue) *8 + ([value substringWithRange:NSMakeRange(5,1)].intValue + [value substringWithRange:NSMakeRange(15,1)].intValue) *4 + ([value substringWithRange:NSMakeRange(6,1)].intValue + [value substringWithRange:NSMakeRange(16,1)].intValue) *2 + [value substringWithRange:NSMakeRange(7,1)].intValue *1 + [value substringWithRange:NSMakeRange(8,1)].intValue *6 + [value substringWithRange:NSMakeRange(9,1)].intValue *3;

return YES;// ID
}else {
return NO;
}
}else {
return NO;
}
default:
return NO;
}
}
4.メールボックスの検証
//
- (BOOL)isEmailAddress{
NSString *emailRegex = @"[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self matches %@",emailRegex];
return [predicate evaluateWithObject:self];
}
5.銀行カードの有効性を検証する。ここはNSStringに書かれた分類です。
/** Luhn
* 16 6 622126~622925 ,7 15 ,
* , , , 16 。
* 16 Luhm :
* 1, 15 1 15, 2
* 2, ,
* 3, 10 。
*/
- (BOOL)bankCardCheck{
NSString * lastNum = [[self substringFromIndex:(self.length-1)] copy];//
NSString * forwardNum = [[self substringToIndex:(self.length -1)] copy];// 15 18
NSMutableArray * forwardArr = [[NSMutableArray alloc] initWithCapacity:0];
for (int i=0; i<forwardNum.length; i++) {
NSString * subStr = [forwardNum substringWithRange:NSMakeRange(i, 1)];
[forwardArr addObject:subStr];
}
NSMutableArray * forwardDescArr = [[NSMutableArray alloc] initWithCapacity:0];
for (int i = (int)(forwardArr.count-1); i> -1; i--) {// 15 18
[forwardDescArr addObject:forwardArr[i]];
}
NSMutableArray * arrOddNum = [[NSMutableArray alloc] initWithCapacity:0];// *2 < 9
NSMutableArray * arrOddNum2 = [[NSMutableArray alloc] initWithCapacity:0];// *2 > 9
NSMutableArray * arrEvenNum = [[NSMutableArray alloc] initWithCapacity:0];//
for (int i=0; i< forwardDescArr.count; i++) {
NSInteger num = [forwardDescArr[i] intValue];
if (i%2) {//
[arrEvenNum addObject:[NSNumber numberWithInteger:num]];
}else{//
if (num * 2 < 9) {
[arrOddNum addObject:[NSNumber numberWithInteger:num * 2]];
}else{
NSInteger decadeNum = (num * 2) / 10;
NSInteger unitNum = (num * 2) % 10;
[arrOddNum2 addObject:[NSNumber numberWithInteger:unitNum]];
[arrOddNum2 addObject:[NSNumber numberWithInteger:decadeNum]];
}
}
}
