Use the user's iCloud key-value file for the free trial durable record and to record the user's article history.

the user needs to pay, either monthly or single time. once the duration is over, if the user needs to improve again then the program can be purchased again else stopped. If it is a monthly payment then it is either an autorenewable subscription or a non-renewing subscription. If it is a single time then it is a non-consumable. But if it is a 'single time' but 'can be purchased again' then it is a consumable.

It is difficult to follow what you are describing. But if you do not DELETE the old (production) app from the device before loading the app from Xcode then you will get that error.

and i want to create iOS app for that website (webview). An app must be more than a website. If your app is more than this website and one feature of the app is that it takes you to the website....and the 'subscription' is only used on the website, not in the app, then you do not need to use IAP. But if the subscription unlocks code or features within the app then you must use IAP.

Please clarify whether you have waited 48 hours after approval and it's still not showing.

Check your price tier to be sure you selected $34.99.

You do not need to show the price. Apple will do that before the user makes a purchase. But if you have multiple IAPs on the store (e.g. 10 widgets, 100 widgets or a 1 month subscription or a 6 month subscription) you might want to. Here is code in Objective C:             [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];             [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];             [numberFormatter setLocale:[[response.products objectAtIndex:0] priceLocale]];             UIAlertController *alert =               [UIAlertController alertControllerWithTitle:@"IAP Products" message:@"The following packages are available for purchase.&#9;&#9;&#9;DESCRIBE PACKAGES GENERICALLY&#9;&#9;&#9;\nPlease select a package." preferredStyle:UIAlertControllerStyleAlert];             for(int iCount=0;iCount<[response.products count];iCount++){                 [alert addAction:[UIAlertAction actionWithTitle:[[[response.products objectAtIndex:iCount] localizedDescription] stringByAppendingFormat:@" %@",[numberFormatter stringFromNumber:[[response.products objectAtIndex:iCount] price]]] style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {                     [[SKPaymentQueue defaultQueue] addTransactionObserver:self];                     SKPayment *paymentRequest= [SKPayment paymentWithProduct:[response.products objectAtIndex:iCount]];                     [[SKPaymentQueue defaultQueue] addPayment:paymentRequest];                 }]];             }             [alert addAction:[UIAlertAction actionWithTitle:@"Check for recent purchase" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {                 [[SKPaymentQueue defaultQueue] addTransactionObserver:self];                 [self performSelector:@selector(endIAP) withObject:nil afterDelay:5.0f]; &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;comment - endIAP uses status to issue an alert&#9;- also in updatedTransactions add a cancelPreviousPerformRequestsWithTarget:                 self->status=@"no approved purchase";             }]];             [alert addAction:[UIAlertAction actionWithTitle:@"Not now, maybe later" style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {                 self->status=@"not now";                 [self endIAP]; &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;comment -&#9;endIAP uses status to issue an alert             }]];             [self presentThisAlert:alert];&#9; &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;comment - presentThisAlert issues an alert

Assuming that the decision to retrieve certain stored files is made within the app and further that within the app you select which files to retrieve then you are 'unlocking code' within the app and must use IAP. The fact that you do it by a 'subscription' doesn't matter. You are having the user pay to unlock code within an app - that's IAP.

It would be great to get an opinion from .... an official response from Apple. not possible one this forum. A secret is only needed for autorenewable subscriptions. The secret is only good for validating the receipt so there is little problem with sharing it with your trusted employees. But the secret could be used to hack the receipt validation process so there is a little concern if one of your employees is driven to hack your system.

if i have a free app, in which i sell clothes, or services, or collect monthly payments. how much is the fee that i will have to pay? You pay nothing except $99/year for a developer account i understand that apple charges 30% on paid apps. but how does it work with free apps with in-app purchases? 30% for IAPs what if i am selling a service or a product does apple take a percentage of that? or just the $99/fee yearly? ibid

If the 'digital product' is used within your app you must sell that digital product using IAP. The physical products can be sold using PayPal. If the user desires to purchase the digital product they would be sent to IAP software. If they desire to purchase a physical product they would be sent to PayPal software.
