Elaborating on Shawn's answer, in <code>- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions</code> you probably have some code like this: <pre><code>- (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]; } </code></pre> You can handle nil productIdentifiers in <code>restoreTransaction:</code> by adding a check to see if the productIdentifier is nil, like this: <pre><code>- (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]; } </code></pre> 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.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
