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.

From SKPaymentTransactionObserver:PaymentQueue.. call:
SKPaymentQueue.default().finishTransaction(transaction)
Note that you can not call for all types. Calling finishTransaction for .purchasing will crash with error. So a for through all transactions is not a complete solution.
When you Call finishTransaction for .purchasing:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot finish a purchasing transaction'
Make sure you have implemented this method:
-(void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray *)transactions;
