In app purchase expiration content - ios

My application currently allows the user to purchase Non-consumable products. I have a Built-in product delivery model which do not involve a developer server.
Im thinking of adding more content which will expire after 1 year. Upon expiration user should have the option to buy the content again. I would prefer the content not being auto renewed. My questions are as follows.
Does the app store only allow magazines and news paper items to be
auto-renewable? The content Im focusing might not have an update
after renewing. Can I renew with the same content after 1 year?
Do I need a server to implement auto-renewable? Can I use the current
Built-in product delivery model to validate the receipts?
What would be the main disadvantage of Non-renewing subscriptions ?
Does it mean that the app store never provides transaction
information paymentQueueRestoreCompletedTransactionsFinished call
back?
Any help on this matter would be highly appreciated.
Thank you

1) It depends on whether you're planning to have your newspaper or magazine in the App Store, or in Newsstand. If you're wanting it to appear in Newsstand, it'll need to have an auto-renewable subscription. If you just want it listed in the regular App Store, you can use whatever IAPs you wish.
2) You don't need a server (despite what the documentation seems to imply), you can verify the receipts from within the app (I've done this in several Newsstand apps). You'll have the receipt as an NSData object, you then need to encode it as a Base64 string and embed it in an HTTP request to Apple's verification servers. You can find a method for doing the conversion from NSData to Base64 string here: How to encode NSData as base64? (iPhone/iPad)
3) Yes, the disadvantage with non-renewing subscriptions is that you have to do all the work in terms of restoring, cancelling, and making the subscription expire (you can't set a time limit in iTunes Connect for them). Check the In App Purchase guide for more details on what your app is responsible for with non-renewing subscriptions (scroll down to the Registering Products with the App Store section): http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/APIOverview/OverviewoftheStoreKitAPI.html

Validate iOS auto-renewable subscriptions from multiple apps

I work for a game developing company which releases at least one game a month. For our true fans we want to start providing a subscription to our games, so they can play all our games (on any platform) without constantly having to buy them.
The idea for iOS is to use the in-app auto-renewable subscription. This results into a receipt which we store in our backend. The backend can validate this receipt and provide the apps with information about the subscription of the user.
This system will solve a lot of problems: You can take the subscription in 1 game, and play all the games as well, on any device you like.
But now we come to the problem: After a month the receipt is not valid anymore, and we need to check in the iTunes store to see if the user still has a valid subscription.
My first idea was to use the "latest_receipt_info" field, to get the latest receipt and validate this. But according the documentation this feature should only be used for iOS 6 receipts:
"Only returned for iOS 6 style transaction receipts for auto-renewable
subscriptions."
source:
https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html#//apple_ref/doc/uid/TP40010573-
Even though I can actually still use this field with my brandnew iOS 10 receipt, I don't think it's smart to use it since it's deprecated.
(another source telling you shouldn't use it anymore: https://forums.developer.apple.com/message/156580#156580)
The advised solution of apple is to implement a SKPaymentTransactionObserver in the app. This will retrieve the latest receipt when it's available, and send this to the backend. Even though this is far from ideal, this could work... however:
This means the app has to be active to retrieve the latest receipt. And in our case it's very well possible a user takes a subscription in app1, and after a couple of days downloads app2, 3 and 4, but never uses app1 again. So in this case the latest receipt will never be fetched (because only the observer of app1 can access the receipt)
To fix this problem we should be able to fetch the receipts from this subscription from any app in our subscription group. But according the documentation on the apple site (https://developer.apple.com/app-store/subscriptions/ ) you can only access a subscription from 1 app, and you have to do the multiple app thing yourself:
You can offer auto-renewable
subscriptions to access multiple apps in your portfolio. Each app must
be approved to use auto-renewable in-app purchases and must be
published under the same developer name on the App Store.
In iTunes Connect, you’ll need to set up separate and equivalent
auto-renewable in-app purchases in each app offered in the multi-app
subscription so that users can subscribe from any app. To avoid users
paying multiple times for the same offering, you are responsible for
verifying that they are subscribers in one of the apps before showing
any subscription options. To do this, consider maintaining an account
management system in which users create an account with your business
to sign in to each app.
So is there any way to do what we want, without forcing the user to go back to the app he used to purchase the subscription every month?
On the last WWDC we went to StoreKit labs and personally asked StoreKit evangelist about this. We were told that the 'latest_receipt_info' field return by iTunes validateReceipt endpoint is exactly what we are suppose to use in order to check if the subscription was renewed or not.
This is not going to be deprecated in the near future but they do have plans for adding some server-to-server communication that solve few of the problems we ran into:
Your server will be able to get notification from Apple regarding any subscription renewal, cancellation, downgrades etc.
In the latest_receipt_info returned by the validateReceipt endpoint few fields will be added, providing information like whether the subscription will be renewed after current one is expired, whether there was a problem charging the user's credit card etc.

Can I store In-App Purchases on the Cloud(Parse)?

Building an iOS App in Swift. Quick question about IAP's I want to implement. Currently, I have my In-App Purchases fixed in my app. Meaning, I would have to push an update to the app in order to change the visible information about the IAP, etc.
Does Apple allow me to store this In-App Purchase data in my cloud(Parse), or does it have to be local? Of course, the IAP's would have to be approved in iTunes Connect, but don't have to be used if they are approved.
My goal is to alternate through different plans without having to go through an entire app update.
I feel like the answer is a big obvious yes, but I just wanted to confirm before I begin coding it all in.
Thanks!
It's up to you to decide where to store In-App Purchases.
Here is Apple documentation about storing in-app purchases data.
How to store product identifiers:
Every product you sell in your app has a unique product identifier.
Your app uses these product identifiers to fetch information about
products from the App Store, such as pricing, and to submit payment
requests when users purchase those products. Your app can either read
its list of product identifiers from a file in its app bundle or fetch
them from your server.
How to store associated content for purchased package:
You can embed that content in your app’s bundle or you can download it
as needed — each approach has its advantages and disadvantages.
Embed smaller files (up to a few megabytes) in your app.
Download larger files when needed.
Personally I want to say that all projects I was working on used remote server for getting in-app purchases data.
You don't need care about app approval in this situation.
Yes, It is possible to store In-App Purchases on the Cloud(Parse).
The in-app purchases for iOS are done through the Apple app store. We do not take a cut or interact with the transaction in any way. We simplify the process of setting up in app purchases, take care of interacting with the Apple server, perform receipt validation to ensure your purchases are done securely, take care of delivering the purchased content through PFFiles if you choose to use this mechanism and also provide an easy to use UI component for use in your app.

Yes, you can do that using parse in swift(youtube)
and parse doc.

IOS InAppPurchase content download from my own server

I am developing an application. In this application new user will get access to download three images from my own PHP server. After downloading 2 images he then needs to purchase subscription for (1-Year) via an in-app-purchase. Then user will be able to download all available images from the server.
After completion of 1 Year subscription the user will need to renew his subscription, otherwise all downloaded content should be deleted from his device.
How can I approach this requirement using InAppPurchase? Which type of InAppPurchase do I have to implement (Consumable, Non consumable or Subscriptions)?
If you want the user to auto-renew, use an Auto-renewing Subscription.
If you want the user to manually renew, use a non-renewing Subscription.
The use cases for both of these are covered pretty clearly in Apple's documentation: "Getting Started with In-App Purchases on iOS and OS X" ( https://developer.apple.com/in-app-purchase/In-App-Purchase-Guidelines.pdf )
The user experience for each of these is different and you'll need to take that into consideration in addition to the coding complexity when you choose which path to take.
There is no one "right" answer, only the one that's right for your intent and audience.

How do I verify IOS In-App Purchasing Receipts in Bulk?

I'm working on an iOS app that will use Apple's in-app purchasing framework to let the user create auto-renewing subscriptions.
I want my server to check periodically that none of the subscriptions have expired. Apple's Receipt Validation Programming Guide describes a verifyReceipt web service that appears to validate a single receipt.
However, if I want to bulk-verify my entire database every few days, is there a better way to do that than a storm of individual verifyReceipt calls?
You don't need to need to bulk-verify your entire database. A subscription is valid for a fixed duration. If the user cancels their subscription then this takes effect at the next renewal period, not immediately.
Apple customer service can refund a subscription if a user has a case (wrong product purchase is one example they give) but this would be a pretty low figure - and your app should also check for a valid subscription when it starts.
So you should only need to verify subscriptions that are known to be expiring "today".
To my knowledge there's no way to send multiple receipts in one bulk request to validate them in the iTunes servers... You have to send one by one. (Multiple requests)...
I don't know if how you are planing to solve this is the best approach. Apple has extended documentation on how to handle auto renewal subscriptions, most of the times you check the validity of the subscription in the app itself.
Check the in-app purchase documentation. It's a very good read if you plan to depend on in-app subscriptions for your business model:

How do auto-renewable in-app-purchase subscriptions work?

My application currently allows the user to subscribe to our service using in-app purchase auto-renewable subscription. The app provides images, 12 images per month, and every month the user needs to renew his/her subscription to see the new content.
I haven't work on the auto-renewable model before, so I have built a model to validate the receipt and it works, but should I check if the user subscription expired or not, and, if so, how?
Also, does the app store only allow magazines and newspaper items to be auto-renewable?
I haven't worked on the auto-renewable model before, so any help on this matter would be highly appreciated.
When a user signs up for an auto-renewable subscription, they continue to be charged until they manually cancel it. This is obviously great from a developer’s point of view, because it takes a lot more effort to cancel something than to just let it continue.
You might already be familiar with a class of apps that use auto-renewable subscriptions already: Newsstand.
Newsstand was first introduced in iOS 5, and allows content providers to easily distribute their newspapers and magazines. With it, Apple introduced the auto-renewable subscription model, which allows you to set a subscription duration and manage renewals automatically through the StoreKit framework.
However, Apple has placed some very strict rules around auto-renewable subscriptions, meaning their usage is (usually) exclusive to Newsstand apps.
So sadly, if you want to provide content or features for a limited duration, outside of Newsstand, then your only option is to use non-renewing subscriptions.
found that here: http://www.raywenderlich.com/36270/in-app-purchases-non-renewing-subscription-tutorial
An auto-renewable subscription is an iOS In-App Purchase category that allows an app to provide and charge for content or features over a set amount of time.
Hear is a very useful link!. It provides almost every details about auto renewable subscription
Auto-Renewable In-App purchases continues charging the user (weekly/monthly/yearly etc.) until they cancel it.
You can check if the subscription has expired using the a validated receipt. It contains subscription expiration date and time.
If you want to lock content if subscription has not renewed, you may want to check receipt info against current date/time, on applicationDidBecomeActive delegate. There are open source libraries that lets you verify receipts locally as well.
And any kind of app can have Auto-Renewable In-App purchases, not just newsstand apps.
