Question

I have uploaded app on appstore.its working fine on io6 but when I uploaded on apple store its rejected due to application crash in iOS7.When I am run it on xcode 4.5 its working fine and I got purchase alertview message but I could not get it on xcode5 and ios7.here is my source code.

- (IBAction)buy {
          activityIndicator.hidden = NO;

          SKMutablePayment *payment = [[[SKMutablePayment alloc] init] autorelease];
         payment.productIdentifier = @"com.test.app.V3";
         [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
        [[SKPaymentQueue defaultQueue] addPayment:payment];

        if ([SKPaymentQueue canMakePayments]) {
            NSLog(@"Parental-controls are disabled");

            SKProductsRequest *productsRequest = [[SKProductsRequest alloc]           initWithProductIdentifiers:[NSSet setWithObject:@"com.test.app.V3"]];
            productsRequest.delegate = self;
            [productsRequest start];
        }
        else {
            NSLog(@"Parental-controls are enabled");
        }
    }

    - (void)viewDidLoad {
        [super viewDidLoad];
    }

    -(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
        SKProduct *validProduct = nil;
        int count = [response.products count];
        if (count > 0) {
            validProduct = [response.products objectAtIndex:0];

        }
        else if (!validProduct) {
            NSLog(@"No Products Available");
        }
    }

    - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
        for (SKPaymentTransaction *transaction in transactions) {
            switch (transaction.transactionState) {

                case SKPaymentTransactionStatePurchasing:
                    //// Stuff Here ////

                    break;

                    [[NSUserDefaults standardUserDefaults] setObject:money.text forKey:@"Balance"];

                    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"ThankYou"];

                    [self exitIAP];

                    break;

                case SKPaymentTransactionStateRestored:
                    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                    break;

                case SKPaymentTransactionStateFailed:
                    if (transaction.error.code != SKErrorPaymentCancelled) {
                        NSLog(@"An Error Encountered");
                    }
                    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                    [self exitIAP];

                    break;
            }
        }
           }

      - (void)exitIAP {
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
      }
  appreciate for any kind of help.

Answer 1

As rckeones says, it will be difficult to track this down without a symbolicated crash report, but given the information we have, these lines intrigue me:

12  DubstepSlots                     0x0017cdce 0x90000 + 970190
13  StoreKit                         0x31a0cdc8 __NotifyObserverAboutChanges     
14  CoreFoundation                   0x2f23b656 CFArrayApplyFunction + 34
15  StoreKit                         0x31a0cd64 -[SKPaymentQueue     _no  

It implies to me that the SKPaymentQueue is calling out to its observers (one being something in your DubstepSlots project), in which it is crashing.

Looking at your code, you are adding this class as an observer:

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

That method has the signature

- (void)addTransactionObserver:(id<SKPaymentTransactionObserver>)observer

Which means that your self object must conform to the SKPaymentTransactionObserver protocol. Luckily, you have the required method - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions; in your code. I'm pretty sure that this is the method where it is crashing. But if you set a breakpoint at the beginning of this method and step through, I'm sure you'll find out what is wrong.

I don't know for sure, but it seems like the lines

8   libobjc.A.dylib                  0x39b7e77e objc_exception_throw + 246
9   CoreFoundation                   0x2f30b8e2 -[NSObject(NSObject)   

indicate that you might be calling a method that does not exist on an object in that method.

Without the symbolicated report, it is hard to judge what exactly is going wrong (we don't even know what line its crashing on!) That should at least get you started in finding where things are going wrong.
