在App Purchase Crashes App中

Question

I have an iOS App that I just submitted an update for. The development version of the app (simulator and my 4S) never crashed and it works just fine. The app got approved today as well as the IAP, but I realized this morning that the iAP was not "cleared for purchase". I just cleared it for purchase, but the app still crashes. The error the iPhone gives (running the app store version) gives the error:

<Error>: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array'

Here is the code where that happens:

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:
(SKProductsResponse *)response
{
    NSArray *myProduct = response.products;
    //this line is where the error occurs
    noAdProduct = [myProduct objectAtIndex:0];
    if (![[[NSUserDefaults standardUserDefaults] objectForKey:@"the id here"] boolValue]) {
        adCell.detailTextLabel.text = [NSString stringWithFormat:@"$%@", noAdProduct.price];
        adCell.userInteractionEnabled = YES;
        adCell.accessoryType = UITableViewCellAccessoryNone;
        adCell.accessoryView = nil;
        [self.tableView reloadData];
    }
}

This happens while requesting a list of available products, which obviously returns the product in the simulator but not in the app. I just added a safeguard against this but I will need to submit it to the App Store again.

Does anyone know why the iAP is not showing up for the App Store version? Do I need to wait for the "cleared for sale" option to go to Apple's servers? Thanks!

Answer 1

Obviously myProduct array is empty. Why this happens is another question, but you should never call objectAtIndex without making sure the requested index exists.

if ([myProduct count] > 0)
    noAdProduct = [myProduct objectAtIndex:0];
else
   // Deal with the situation when the array is empty.
