React-native-iap: iOS: This in-app purchase has already been bought.

@siderakis Yeah strange. I've already patched this problem like told in stackoverflow but still occurring in some devices. I am willing to fix this too. Which device are you using?

@siderakis This might solve your app in bad state I guess. Could you try?

I tried it and it didn't work. I also reinstalled the app and that didn't help. It's running on an iPad.

I set a breakpoint and it looks like currentQueue.transactions is empty

From SKPaymentQueue.h

// Array of unfinished SKPaymentTransactions.  Only valid while the queue has observers.  Updated asynchronously.
@property(nonatomic, readonly) NSArray<SKPaymentTransaction *> *transactions NS_AVAILABLE_IOS(3_0);

@end

Maybe I called it too soon

I called the code later in the programs execution and it fixed the issue.

@siderakis Sorry for bothering. But, what code did you call ?
The transactions array is a property, not method, which is not in our code.
Did you mean finishTransaction ?

I was calling this native code.

When I called it in didFinishLaunchingWithOptions currentQueue.transactions was empty, but calling it in applicationDidBecomeActive worked.

This worked:

- (void)applicationDidBecomeActive:(UIApplication *)application
{
  // take current payment queue
  SKPaymentQueue* currentQueue = [SKPaymentQueue defaultQueue];
  [currentQueue restoreCompletedTransactions];
  // finish ALL transactions in queue
  //  [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
  [currentQueue.transactions enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
    [currentQueue finishTransaction:(SKPaymentTransaction *)obj];
  }]; 
}

I'm not sure how but maybe we can expose this functionality in the library?

@siderakis Yes. That's what I meant in issue #259 .
I think that action can be anywhere after applicationDidBecomeActive.
So, I will expose that method to JS side, that user can call it any time.
Thank you for your advice.

@JJMoon, I have the same issue, When can we expect a resolution for exposing a method as you mentioned above. Thanks.

@sivrihuseyin Problem is well known now. We will make the patch this weekend. Thank you to all issuers.

We've released the expected solution in 2.2.0. Could you follow readme and try this line of codes?

Hello Hyo Chan,

Thank you for the information.

I have installed the version 2.2.0 and tried the code. Unfortunately, the
issue is not fixed yet. think that the function, *clearTransaction *has not
been exported. In reactNative environment there is no clearTransaction
function inside RNIap.

I checked the file index.d.ts and I couldn't see the function as
clearTransaction in this. file.

Kind regards,

Huseyin

It is fixed with the version 2.2.0 by applying clearTransaction function. Thank you
