I am stuck with setting up my in-app purchases.
I can't get to get this right:
SKPayment *paymentRequest = [SKPayment paymentWithProduct: #"co.za.nideo.100shotsbuybeer"];
I got it from
SKPayment *paymentRequest = [SKPayment paymentWithProductIdentifiers: #"co.za.nideo.100shotsbuybeer"];
but this seems to be deprecated. How can I get the first piece of code to work?
It seems to nee a SKProduct but I don't know how to create/init such an object.
According to the StoreKit docs and [1] you'd have to:
Create an SKProductsRequest with your product identifiers (initWithProductIdentifiers:)
Set yourself as the delegate
Send this request to Apple (start method)
The Response will call your delegates productsRequest:didReceiveResponse: which contains an SKProductsResponse object
You extract the SKProduct objects from the products property and display them, saving the objects for further purchase.
This seems in line with Important: You must make a product request for a particular product identifier before allowing the user to purchase that product. Retrieving product information from the App Store ensures that you are using a valid product identifier for a product you have marked available for sale in iTunes Connect. from [1]

I have simply problem with
SKPayment *payment = [SKPayment paymentWithProductIdentifier:#"ident"];
The problem is that paymentWithProductIdentifier is deprecated.
I found on the internet that I can use
paymentWithProduct
But the problem is that I don't know how to get SKProduct.
I wrote something like this:
SKProductsResponse *response;
SKProduct *validProduct = [response.products objectAtIndex:0];
SKPayment *payment = [SKPayment paymentWithProduct:validProduct];
But it doesn't work.
Where is the problem?
Thanks in advance.
Your code uses *response without initializing it - that is the immediate problem.
However, the bigger issues is getting the SKProduct object. The basic method here is that before presenting the ability to purchase items to the user, you need to put a request into the App Store to retrieve the SKProduct objects you may want to show the user. Each SKProduct contains the localized price and description information you need to present to the user. I structure my code to retrieve the product array on entry to the buy screen. Depending on your app, you may need to call it earlier.
You start with the skus of a list of possible purchaseable items. Then create an SKProductsRequest object using that set of skus (SKProductsRequest initWithProductIdentifiers:). Also, supply an SKProductsRequestDelegate to receive the response. Then start the request. When it calls into the delegate using didReceiveResponse:, you can save the array in the response containing the SKProduct objects. It also returns a list of invalid products that you cannot present to the user. Only present items for which you have received an SKProduct object in the callback.
When it comes time to actually initiate the payment, you pull the correct SKProduct object from the array passed into the SKProductsRequestDelegate didReceiveResponse: method to create the payment object.
I have an Iphone application in which i am using two types of purchases.Non consumable products and a subscription.For subscription i have to use mkstorekit4 anyway.So i need to implement the nonconsumable also in the storekit4.Anybody knows the steps to integrate nonconsumable products with mkstorekit4.Can anybody help me.
As form me,if you've already managed how to add auto renew in your app, you are a guru of in-app,so adding a non-consumble would as easy as a pie,even without a MkStoreKit.
You just make a purchase and save it to UserDefaults.
And with MK you just add it to non-consumable part of your MK plist and add a couple of lines of code-and it's done)
Just a button,that makes a purchase,i think)
Update
This article just confirms, what i told.
http://blog.mugunthkumar.com/coding/using-mkstorekit-in-your-apps/
Configuring for Non consumables :
Non-consumables need no extra configuration. Just enter the list of product ids in the plist file.
For checking whether the user has purchased the feature, you can call a function like,
if([MKStoreManager isFeaturePurchased:kFeatureID]) { //unlock it }
To purchase a feature, just call
[[MKStoreManager sharedManager] buyFeature:kFeatureAId onComplete:^(NSString* purchasedFeature) { NSLog(#"Purchased: %#", purchasedFeature); } onCancelled:^ { NSLog(#"User Cancelled Transaction"); }];
I'm trying to make "In App Purchase " works in my iphone app.
I created some products and a few test accounts in itunes connect.
I have no problem to retreive the products data (prices etc..) but when I try to make a payment
- I am asked to log in
- I use a test account
-> the transaction always fail with the following error :
failedTransaction with error : Error Domain=SKErrorDomain Code=2 "Connexion à l’iTunes Store impossible" UserInfo=0x65d02a0 {NSLocalizedDescription=Connexion à l’iTunes Store impossible}
I tried with several products and test account (even in other stores like us) but I still get the same error...
NB : I think it worked fine the first time I tried but never still
Any idea will be welcome !
Thanks
For me, I just scoured my code until I found my mistake. I was so certain everything was fine, but it was not. When I requested product information from the store, I used the correct Product Identifier:
self.productRequest= [[[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObject: #"com.popculturesoft.RC_vCar.fullVersion"]] autorelease];
However, when I went to create the payment, I used the incorrect Product Identifier:
SKPayment *payment = [SKPayment paymentWithProductIdentifier:#"com.popculturesoft.RC_vCar_Lite.fullVerson"];
Using the product Identifier for the payment is not the correct way to do it, although it allows you to do it. It is better to use an SKProduct object. (I had set the fullProduct property earlier in the code:
SKPayment *payment = [SKPayment paymentWithProduct:self.fullProduct];
I was absolutely certain that the store was down, and that was the problem. But the next day I decided to start from the beginning of the process, as described in http://developer.apple.com/library/ios/#technotes/tn2259/_index.html. This is when I found that my incorrect Product Identifier was the problem.
Check out this thread. It seems to be a problem with the Sandbox. Lot's of people having this issue-
iPhone storekit sandbox stopped working
I had the same symptoms and in my case the problem was that I had a test user account with the same name as a real Apple ID account. I resolved the problem by creating a different test user account.
Our app has a list of locked products that share the same consumable product id (i.e. one consumable product id for many products). Our server provides me with a list of products and the product id associated with them:
item name="itemA" iphoneProductId="consumable.test.1"
item name="itemB" iphoneProductId="consumable.test.1"
item name="itemC" iphoneProductId="consumable.test.1"
We chose consumable because our items are created dynamically and need to be available to the user instantly (please don't reply suggesting that we use non-consumable, there are a lot of other reasons that are too hard to explain without me giving away private details about the company we are working with, as to why we are using consumable). This allows us to have multiple products share the same price.
When the user purchases itemA (for example), the item is unlocked. However, sometimes, when the user then tries to be itemB, Apple return with 'You have already purchased this but it hasn't been downloaded. Tap OK to download it now’. This should surely never happen for a consumable item. I know our system is quite complex but as far as the apple store kit is concerned, are simply just buying the same product again.
Could this just be a sandbox issue? We can't test in live as the app isn't released yet. In fact, this whole problem is holding off the release as our client is as concerned as we are about this problem.
I've followed the same code from the iphone documentation and the few in app purchase tutorials out there. I see that a lot of people on the forums seem to have witnessed the 'already purchased' dialog above for consumable products, but none of them ever get answered.
Please help! Thanks
The problem is that you are never finishing the transaction. You need to remove it from the queue.
Like:
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
I'll assume you've called -[SKPaymentQueue finishTransaction:].
Off the top of my head, there are a few possibilities:
The store hasn't received the "finish" message yet (I don't know what ordering guarantees there are).
You're trying to purchase a second item before calling finishTransaction: on the first, and the App Store thinks it's a replay.
The App Store detects when you appear to be purchasing the same item repeatedly, and assumes that something must have gone wrong.
A hack is to cycle through a list of several (10? 100?) consumables, assuming that when you get back to one earlier in the list, it will have finished processing.
An alternative solution is to pre-allocate a lot of non-consumables ("product.1", "product.2", ..., "product.100") and assign ones with the appropriate price to products on the server. Changing prices can then be done on iTunes Connect, or by assigning additional product IDs as necessary.
Thanks for your quick response, but my app does seem to be finishing the transaction, etc.
My project's in app purchase classes have become quite complex so I reverted to creating a new basic project with a test consumable product and the standard implementation of in app purchase manager/observer taken from this open source:
http://blog.mugunthkumar.com/coding/iphone-tutorial-%E2%80%93-in-app-purchases/#idc-cover
The same problem occurs. This is the order:
1. Buy the consumable product for the first time (below is the debug I printed out)
_MKStoreManager: buyFeature:test.consumable.1
__MKStoreObserver: SKPaymentTransactionStatePurchased
__MKStoreObserver: completeTransaction
_MKStoreManager: provideContent
2. "Thank you for your purchase" dialog is displayed by Apple
3. Buy the consumable product for the second time:
_MKStoreManager: buyFeature:test.consumable.1
__MKStoreObserver: SKPaymentTransactionStatePurchased
__MKStoreObserver: completeTransaction
_MKStoreManager: provideContent
__MKStoreObserver: SKPaymentTransactionStateFailed
__MKStoreObserver: failedTransaction
4. "You've already purchased this but it hasn't been downloaded. Tap OK to download it now. [Environment: Sandbox]" dialog is displayed by apple.
It just doesn't make sense in step 3 that the transaction is both purchased then failed at the same time. Do you have any ideas.
It is not worth using consumable product for non-cosumable, because Apple will reject it. Here is what happened to me:
I have had the same issue. The message explaining that you have already purchased the item appears only once in a while and mostly if you purchase a lot of things - one after the other immeadiately.
We have put it for review in the App Store anyway and got the following answer:
.....
We have completed the review of your in-app purchase but cannot post it to the App Store because the Purchasability Type is not set correctly. For information on Purchasing and Currency guidelines, please see section 11 of the App Store Review Guidelines [ https://developer.apple.com/appstore/resources/approval/guidelines.html ].
.....
The purchase of a [magazine issue] is set to "consumable", however based on product functionality it should be set as non-consumable instead.
.........
You are required to create a new in-app purchase product with the correct purchasability type.
..........
I hope this saves someone time and headaches.
I was facing the same problems. The mistake I did was deallocating the purchase before the finishTransaction was sent. Make sure you handle the transaction result after finishing the transaction
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
BOOL success = YES;
for (SKPaymentTransaction *transaction in transactions){
switch (transaction.transactionState){
case SKPaymentTransactionStatePurchased:
success = YES;
break;
case SKPaymentTransactionStateFailed:
if (transaction.error.code == SKErrorPaymentCancelled){
if(DEBUG) NSLog(#"Transaction failed => Payment cancelled.");
}else if (transaction.error.code == SKErrorPaymentInvalid){
if(DEBUG) NSLog(#"Transaction failed => Payment invalid.");
}else if (transaction.error.code == SKErrorPaymentNotAllowed){
if(DEBUG) NSLog(#"Transaction failed => Payment not allowed.");
}else if (transaction.error.code == SKErrorClientInvalid){
if(DEBUG) NSLog(#"Transaction failed => client invalid.");
}else if (transaction.error.code == SKErrorUnknown){
if(DEBUG) NSLog(#"Transaction failed => unknown error.");
}else{
if(DEBUG) NSLog(#"I have no idea.");
}
success = NO;
break;
case SKPaymentTransactionStateRestored:
success = YES;
break;
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(#"transaction finished: %#", transaction);
}
if(success){
// do something
}
}
Hope that helps some of you.
Cheers,

You should put this line [[SKPaymentQueue defaultQueue] finishTransaction:transaction] after the transaction over whether you are doing fresh purchase or restore purchase.
[[SKPaymentQueue defaultQueue] addTransactionObserver:observer];
make sure you have added this method on the controller handling requests.
I am developing a iPhone app. For that i have successfully add the In App Purchase functionality. It is working perfectly for a single item purchase. My problem is that How can i do this for multiple item purchase with single purchase request to App Store?
Can anybody help me for this?
You can use quantity property in SKPayment... Read how many items you want from user then pass this value to payment.quantity(By default it is 1).
SKPayment *payment = [SKPayment paymentWithProductIdentifier:inProductID];
payment.quantity = mNoOfItemsYouWant;
[[SKPaymentQueue defaultQueue]addTransactionObserver:mTransactionObserver];
[[SKPaymentQueue defaultQueue] addPayment:payment];
Each purchase needs authorization from the user, so I don't think you can do what you want to.
However, you can make a single in-app purchase which is priced and behaves like multiple items clubbed together. For instance:
Item 1 - $.99
Item 2 - $.99
Item 3 - $.99
Bundle (includes 1, 2, 3) - $1.99
