Objective c 如何为我的IAP集成触摸ID？

我的IAP有以下代码，它可以成功运行，但不支持那些想使用Touch ID购买的用户。我需要向removeAdsButton方法中添加什么来支持这一点？如果我不添加任何支持Touch ID的内容，事务是否仍能成功处理

- (void)removeAdsButton {
    if([SKPaymentQueue canMakePayments]){

        SKProductsRequest *productsRequest = [[SKProductsRequest alloc]
        initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
        productsRequest.delegate = self;
        [productsRequest start];
    }
    else{
    }
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    SKProduct *validProduct = nil;
    int count = (int)[response.products count];
    if(count > 0){
        validProduct = [response.products objectAtIndex:0];
        [self purchase:validProduct];
    }
    else if(!validProduct){
    }
}

- (void)purchase:(SKProduct *)product{
    SKPayment *payment = [SKPayment paymentWithProduct:product];

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue{
    for(SKPaymentTransaction *transaction in queue.transactions){

        if(transaction.transactionState == SKPaymentTransactionStateRestored){
            [self doRemoveAds];
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
        }
    }   
}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{

    for(SKPaymentTransaction *transaction in transactions){

        switch(transaction.transactionState){
            case SKPaymentTransactionStateDeferred: 
                break;
            case SKPaymentTransactionStatePurchasing:
                break;
            case SKPaymentTransactionStatePurchased:
                [self doRemoveAds];
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                if(transaction.error.code == SKErrorPaymentCancelled){
                }
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
        }
    }
}

- (void)restorePurchasesButton {
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

- (void)doRemoveAds{
    //Does my ad removal stuff.
}

对不起，我没有跟随。我读到的唯一相关内容是必须在开发人员端设置Touch ID。这意味着，如果我保持原样，那些在应用商店购买时启用了Touch ID的人只会被提示输入他们的密码，密码应该可以正常工作？对不起，我没有这么做。我读到的唯一相关内容是必须在开发人员端设置Touch ID。这就意味着，如果我让它保持原样，那些在应用商店购买时启用了Touch ID的人只会被提示输入他们的密码，这样就可以正常工作了？
