Question

I’ve got a very strange problem recently. I have a code which processes inApp purchases in my app. I haven’t changed anything in the code for month and this week I got a crash when calling the following method:

//
// call this before making a purchase
//
- (BOOL)canMakePurchases
{return [SKPaymentQueue canMakePayments];
}

I’ve tried to perform bt command in gdb and got following:

What’s going on? I can’t understand the reason why the code which worked for month without any problem now giving me a crash?
I’ve tried to rebuild provisioning profiles from scratch, reset my iPad but still no luck
Thanks in advance for any clues!

Answer 1

since you are trying for SKPaymentQueue canMakePayments try both in device and simulator.. if it crashes in both.. then it got to be code error..then post the code.
