I am getting an error when trying to restore purchases in iOS. The purchase of the (yearly renewable) subscription works fine. However once I delete the app, reinstall, and call Restore Purchase, Xcode spits out this error:
UnityIAP: restoreCompletedTransactionsFailedWithError
RestorePurchases continuing: False. If no further messages, no purchases available to restore.
However If I try to purchase the product through the original purchase button, I get an “You’re currently subscribed to this.” Message. So somewhere in the store Apple must have a record of this purchase…
This is my RestorePurchases method:
public void RestorePurchases()
{
// If Purchasing has not yet been set up ...
if (!IsInitialized())
{
// ... report the situation and stop restoring. Consider either waiting longer, or retrying initialization.
Debug.Log("RestorePurchases FAIL. Not initialized.");
return;
}
// If we are running on an Apple device ...
if (Application.platform == RuntimePlatform.IPhonePlayer ||
Application.platform == RuntimePlatform.OSXPlayer)
{
// ... begin restoring purchases
Debug.Log("RestorePurchases started ...");
// Fetch the Apple store-specific subsystem.
var apple = storeExtensionProvider.GetExtension<IAppleExtensions>();
// Begin the asynchronous process of restoring purchases. Expect a confirmation response in
// the Action<bool> below, and ProcessPurchase if there are previously purchased products to restore.
apple.RestoreTransactions((result) =>
{
// The first phase of restoration. If no more responses are received on ProcessPurchase then
// no purchases are available to be restored.
Debug.Log("RestorePurchases continuing: " + result + ". If no further messages, no purchases available to restore.");
});
}
// Otherwise ...
else
{
// We are not running on an Apple device. No work is necessary to restore purchases.
Debug.Log("RestorePurchases FAIL. Not supported on this platform. Current = " + Application.platform);
}
}
—Some other info that may be pertinent:
I have a method that tries to get the user’s subscription status directly from Apple after the StoreListener has been initialized (soon after startup). This method works fine after initial purchase. However after I delete and reinstall the app, I get a No Receipt Found error.
I have tried calling RefreshAppReceipt, which seems to do something. Once I hard close and reopen the app, the store returns the subscription status correctly. However calling RefreshAppReceipt and then RestorePurchases as a callback from that does not work.
Any tips for getting RestorePurchases to work would be much appreciated!
