I have a few users who have reported that after attempting an in app purchase the app is now crashing on startup. I have asked them to delete and reinstall the app which has not worked, and attempted to ask them to go into airplane mode to stop any network communication that has not worked.
I am unable to replicate the error in anyway on my devices and my in app purchase goes through just fine in sandbox and production modes. My thought is that somehow their transaction received a nil productIdentifier which is causing the startup crash but I am not sure what transaction observer methods get called at app startup that I can fix the issue for them.
Is there someway to "clear" the transaction queue or otherwise test for nil productidentifiers on start up and allow these users to get the app at least running again? I've done several hundred in app purchases using the code below and this just recently began happening. Which of the helper methods get called on app startup?
In AppDelegate.m
[[SKPaymentQueue defaultQueue] addTransactionObserver:[MovieClockIAPHelper sharedHelper]];
In app helper code:
- (id)initWithProductIdentifiers:(NSSet *)productIdentifiers {
if ((self = [super init])) {
// Store product identifiers
_productIdentifiers = [productIdentifiers retain];
// Check for previously purchased products
NSMutableSet * purchasedProducts = [NSMutableSet set];
for (NSString * productIdentifier in _productIdentifiers) {
BOOL productPurchased = [[NSUserDefaults standardUserDefaults] boolForKey:productIdentifier];
if (productPurchased) {
[purchasedProducts addObject:productIdentifier];
NSLog(#"Previously purchased: %#", productIdentifier);
}
else{
NSLog(#"Not purchased: %#", productIdentifier);
}
}
self.purchasedProducts = purchasedProducts;
}
return self;
}

self.request = [[[SKProductsRequest alloc] initWithProductIdentifiers:_productIdentifiers] autorelease];
_request.delegate = self;
[_request start];
}
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
NSLog(#"Received products results...");
self.products = response.products;
self.request = nil;
[[NSNotificationCenter defaultCenter] postNotificationName:kProductsLoadedNotification object:_products];
}

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

}

[[SKPaymentQueue defaultQueue] finishTransaction: transaction];

I've run into a similar issue when the transaction is in the SKPaymentTransactionStateRestored. My testing has indicated this might be an issue with IOS 7.0.3, but I have not been able to verify this.
StoreKit keeps a persistent list of transactions that your application must finish. As you've noted the transaction will be reported on every startup until it is finished.
The solution that we implemented is to check if the product identifier is nil before usage from the entry point:
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
Even when we received a transaction with a nil product identifier we were able to successfully call finishTransaction.
I hope this helps.
One of my users complained four days ago about the same problem and was able to send me a crash log. He uses iOS 7.0.3 on iPhone 5,2. Crash occurs after identifying a SKPaymentTransactionStateRestored while trying to build a dictionary with the productIdentifier property from originalTransaction.payment:
NSDictionary* userInfoDict = #{#"productID":transaction.payment.productIdentifier};
I think that either originalTransaction or its properties payment or productIdentifier is nil. I stored the productIdentifier from transaction.payment.productIdentifier instead from transaction.originalTransaction.payment.productIdentifier while restoring and use that as productIdentifier from then on:
case SKPaymentTransactionStateRestored:
{
NSString *productID = transaction.originalTransaction.payment.productIdentifier;
if (!productID) {
productID = transaction.payment.productIdentifier;
}
[self handlePurchaseSuccessful:transaction.originalTransaction productIdentifier:productID];
}
Still waiting for review / feedback if that fixes the issue.
Elaborating on Shawn's answer, in - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions you probably have some code like this:
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions)
{
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchased:
[self completeTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];
default:
break;
}
}
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
/* Handle restore here */
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
You can handle nil productIdentifiers in restoreTransaction: by adding a check to see if the productIdentifier is nil, like this:
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
if (!transaction.originalTransaction.payment.productIdentifier) {
NSLog(#"productIdentifier is nil; Apple bug?");
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
return;
}
/* Handle restore here */
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
This technique fixed the problem for me in my app. The app started, logged "productIdentifier is nil; Apple bug?" and didn't crash. When I then manually re-restored transactions, Apple sent a valid transaction, and the app worked as designed.
I fixed this issue as Marimba posted above and it helped for our customers:
case SKPaymentTransactionStateRestored:
{
NSString *productID = transaction.originalTransaction.payment.productIdentifier;
if (productID == nil) {
productID = transaction.payment.productIdentifier;
}
[self handlePurchaseSuccessful:transaction.originalTransaction productIdentifier:productID];
}
I had the same problem paymentQueue:updatedTransactions: was being called with SKPaymentTransaction instances with a state of SKPaymentTransactionStateRestored and a nil productIdentifier in the originalTransaction.
It sounds really weird and might be a 7.0.3 SDK bug.
Do you all still compile with the SDK 6 ?
I'm about to resubmit my app to the store to see if the issue gets fixed but just finishing such transactions but I hope other transactions with a valid productIdentifier are going to be processed now that the app won't crash so that I know what to restore.

I have implemented in-app purchase in my app. My problem is when a new user clicks on restore button, the process is not stopped after completing 1 cycle And execute again and again. After executing 3 to 4 times process get stopped.
I want to stop process instant when a new user doesn't have any purchased transaction.
Here is code of my IAP class.
- (void)restorePurchases
{
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

[ProgressHUD dismiss];
}
// Sent when transactions are removed from the queue (via finishTransaction:).
- (void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray *)transactions

Hopefully this is enough information to help me solve my problem.
I am setting up In App Purchases via a templated source code that was given to me. In my MKStoreManager.m file, where I set up the featureID's for my in app purchases (Ex: static NSString *featureAId = #"com.logannat.myfirstgameTier1";)
When clicking on the actual button in the game, a method
- (void) buyFeature:(SKProduct*) product
{
if ([SKPaymentQueue canMakePayments])
{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
}
ends up getting called. I set a break point, and found the error to be in the last line of that code.
The variables that show up in the break point state are:
self = (MKStoreManager *)"reference number"
product = (SKProduct *) nil
and
payment = (SKPayment *) "reference number"
I can not seem to figure out what the problem is here. Any help would be much appreciated, thank you.
i do not have swift Right now so i am giving you Xcode code please convert the syntax accordingly its not so difficult.
so here is the complete life cycle for the in app purchased.
in your header file call these delegates and setup the bool for checking the status of you purchased
like that
#import <UIKit/UIKit.h>
BOOL arefavorite_access;
BOOL areAdsRemoved;
#interface ViewController : UIViewController<SKProductsRequestDelegate, SKPaymentTransactionObserver>{
}
- (IBAction)purchase;
- (IBAction)restore;
- (IBAction)tapsRemoveAds:(id)sender;

one you need to hockup this tapsRemoveAds method on touchupinside of you button selector ant it will start working.

I had the same problem and honestly saying it wasn't solved. It's much easier to implement IAPs with Parse. It takes just few lines of code and it really works. Read this, I'm sure it will help you:

I have successfully implemented my ad removal non-consumable in-app purchase. I read that I must also have a "restore" button in my app. I have tried implementing a restore function for the last two days, reading all other posts on stackoverflow and nothing has worked for me. When the restore button is pressed, it requests an email and password as expected but even if I haven't previously purchased the product on that Apple ID it will restore it anyway. Below is the code i am using. Any help will be greatly appreciated!
- (IBAction)RestoreProduct:(id)sender {
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

I'm guessing your issue is that you are also calling
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
immediately above:
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
Delete that first line and you are probably good to go.
EDIT:
Based on the comments below, sounds like the [self unlockfeature] line is the culprit :-)

Add

to

However I get the NSLog No Product Available. I have checked to make sure I have added the correct Product ID. I am at a loss to what to do and have been at this for several hours.

If it's a debug build you probably need to add a sandbox user on iTunes connect this will allow you to use IAP that have not been reviewed yet. Note this user should match your iTunes connect account.
