In App Purchase Bug - SKProduct Request

Question

Hi,
This time I am struggling with two very strange problems. The In App Purchase functionality seems buggy.
Problem 1:
The SKProductRequest works on one device (iOS version 4.02), but not on the other (iOS 4.2). None of the devices are jailbreaked, both are the same model (iPhone 4). The one on which the request is not working, just fails (but without crashing):
- (void)request:(SKRequest *)request didFailWithError:(NSError *)error
The SKProduct Request starts automatically with the application launch. But and if for any reason (e.g. a network timeout) the user is able to "update" the price list (=re-initiating the SKProduct request) If re-initiated, the app is crashing. The wired thing:
Problem 2:
The bug only appears, if the device is not connected to XCode while running. In other words, I am able to update the SKProduct Request as often as possible if the device is connected to XCode without any crash- the code seems to work. -> I am not able to trace any possible bug with the help of XCode, because the error does not appear on the device if it is connected..
- (void) requestProductData {
if(isFinishedProductRequest) {
NSLog(@"request products for %@", identifierCash);
self._request = [[SKProductsRequest alloc]
initWithProductIdentifiers:
[NSSet setWithObject: identifierCash]];
_request.delegate = self;
isFinishedProductRequest = FALSE;
[_request start];
- (void)requestDidFinish:(SKRequest *)request {
NSLog(@"purchase request finished");
isFinishedProductRequest = TRUE;
if ( [cashServiceDelegate respondsToSelector:@selector(appleProductRequestDidFinish)]){
[cashServiceDelegate appleProductRequestDidFinish];
[self._request release];
and the cash delegate
- (void) appleProductRequestDidFinish {
isFinishedAppleCashRequest = TRUE;
if (applePaymentTransactionController.productsArray != nil && [applePaymentTransactionController.productsArray count] > 0) {
SKProduct * product = [applePaymentTransactionController.productsArray objectAtIndex:0];
NSLog(@"%@", [product localizedDescription]);
price = [[product price] floatValue];
priceLocale = [product priceLocale];
if ([viewDelegate respondsToSelector:@selector(updatePrice)]){
[viewDelegate performSelector:@selector(updatePrice)];
}else {
[self alertNoAppleProducts];
if ([viewDelegate respondsToSelector:@selector(hideSmallLoadingView)]){
[viewDelegate performSelector:@selector(hideSmallLoadingView)];
I was also looking at the XCode Organizer Device Logs, but they were not really helpful. I will post them, when I will get the 2nd device where the SKProduct Request is working (on mine, its not)

Answer 1

I could solve my two problems.
1.
To start in app purchase again on the one mobile, I just had to delete and reinstall the app. The simple thing This list was helpful http://troybrant.net/blog/2010/01/invalid-product-ids/
2.
The crash when re-calling the SKProductRequest was because i had to super-deallocs in my dealloc method. Sluttery.. - but I am confused why two super-deallocs are working when the app is running in XCode..
