MKStoreKit crash on iOS 7 with SIGTRAP error

Question

I have been over and over this live app crash log and cannot find the problem:

1    CoreFoundation  _CFHash + 130
2    CoreFoundation  CFBasicHashFindBucket + 724
3    CoreFoundation  _CFDictionaryGetValue + 99
4    CoreFoundation  -[CFXPreferencesPropertyListSource setValue:forKey:] + 39
5    CoreFoundation  _CFXPreferencesSetValue + 139
6    CoreFoundation  _CFPreferencesSetAppValue + 45
7    Foundation  -[NSUserDefaults(NSUserDefaults) setObject:forKey:] + 61
8    MyApp   -[MKStoreManager rememberPurchaseOfProduct:withReceipt:] (MKStoreManager.m:884)
9    MyApp   -[MKStoreManager provideContent:forReceipt:hostedContent:] (MKStoreManager.m:848)
10   MyApp   -[MKStoreManager restoreTransaction:] (MKStoreManager.m:1004)
11   MyApp   -[MKStoreManager paymentQueue:updatedTransactions:] (MKStoreManager.m:911)
12   StoreKit    __NotifyObserverAboutChanges + 85

Here is the code that I believe is associated with the crash(es!):

- (void)rememberPurchaseOfProduct:(NSString*) productIdentifier withReceipt:(NSData*) receiptData {

    NSDictionary *allConsumables = [[MKStoreManager storeKitItems] objectForKey:@"Consumables"];
    if([[allConsumables allKeys] containsObject:productIdentifier])
    {
        NSDictionary *thisConsumableDict = [allConsumables objectForKey:productIdentifier];
        NSInteger quantityPurchased = [[thisConsumableDict objectForKey:@"Count"] integerValue];
        NSString* productPurchased = [thisConsumableDict objectForKey:@"Name"];

        NSInteger oldCount = [[MKStoreManager numberForKey:productPurchased] integerValue];
        NSInteger newCount = oldCount + quantityPurchased;

        [MKStoreManager setObject:[NSNumber numberWithInteger:newCount] forKey:productPurchased];
    }
    else
    {
        [MKStoreManager setObject:[NSNumber numberWithBool:YES] forKey:productIdentifier];

        //set flag in NSUserDefaults as another place we chan check to see if they have purchased the app
        //we may not want to check this, however, as an OR, since it can be easily jailbroken
        [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }

    [MKStoreManager setObject:receiptData forKey:[NSString stringWithFormat:@"%@-receipt", productIdentifier]];
}

I have been using this same code for years with no problem. Can anyone please help to point me in the right direction?

(too long for SO to post the rest but I can add it in a comment if anyone thinks it could be helpful)

What is the actual error shown in the crash log? And which line is line 884? — rmaddy, Nov 04 '13 at 18:01
Line 884 is: [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier]; I am getting the crash report from a reporting service so I have a summary of the report that show "Reason: No reason string found. Exception Type: SIGTRAP" — SAHM, Nov 04 '13 at 18:07
Crashes are in iOS 7 only, primarily in 7.0.3 though it did happen once in 7.0.1; across all devices — SAHM, Nov 04 '13 at 18:12
Is it possible that `productIdentifier` is `nil`? Though I suppose that would cause problems earlier on. The `TRUE` should be `YES` but that wouldn't cause the crash. — rmaddy, Nov 04 '13 at 18:13
Users have told me that they go through the process to purchase the app, then the content is not delivered; and that this is happening when they tap the restore button — SAHM, Nov 04 '13 at 18:14
@rmaddy any more thoughts on this? this particular piece of code has been working no problem since April, do you have any thoughts on what could have changed in iOS 7? — SAHM, Nov 04 '13 at 21:02
Without knowing the error I have no further ideas. I do know that iOS 7.0.3 is the first minor update to iOS that has broken one of my apps due to additional assertion checks. — rmaddy, Nov 04 '13 at 21:03
I am showing my novice here but I am not really sure what assertion checks are. I wonder if they could be involved in this scenario? Is there a place where these changes are documented? — SAHM, Nov 04 '13 at 21:39
I added the (almost) full crash log. Can't find too much info for this error, especially in live apps. Any help would be greatly appreciated. — SAHM, Nov 04 '13 at 23:50
I'm seeing the same issue. Users purchase IAP, and nothing gets delivered, then they try to restore, and the app crashes, and every time since then they can't even launch the app. — eanticev, Nov 12 '13 at 17:07
I'm also seeing a similar issue. Would be very interested in hearing how you solve this. — thomax, Nov 19 '13 at 09:01
I also have a similar issue - It's a lot worse given iOS7 even though the code works on my dev devices — Nate Murray, Nov 21 '13 at 15:07
@rmaddy you're right - apple IS returning a nil productIdentifier. So weird. see: https://github.com/MugunthKumar/MKStoreKit/pull/176 for this exact issue. — Nate Murray, Nov 21 '13 at 15:13

productIdentifier is nil as @rmaddy suggests in the comments. Other developers are reporting this issue on the MKStoreKit Github issues https://github.com/MugunthKumar/MKStoreKit/pull/176

The suggested fix is here: https://github.com/dfabulich/MKStoreKit/commit/4b8adb442f1d7b7a9541feab5e319969369d3f95 by Dan Fabulich (not me).

In MKStoreManager.m -(void) provideContent: (NSString*) productIdentifier add a nil check at the top:

if (!productIdentifier) {
  NSLog(@"productIdentifier is nil; Apple bug?");
  return;
}
