Question

I have InApp purchasing setup in my app. I am having some weird behavior though. Each time I start up the app I call

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

to setup the initial observer. However this immediately triggers

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions

with a full array of every transaction. I have tried just calling

[[SKPaymentQueue defaultQueue] finishTransaction: transaction];

on each of these transaction then restarting the app again but paymentQueue is still trigger as soon as I call addTransactionObserver. My main goal right now is just to flush the transaction queue and start clean. I don’t know how I got into this state, nor how to get out of it.

Make sure you have implemented this method:

-(void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray *)transactions;
