ios - iOS InApp购买已更新交易:无法区分新购买和还原

据我所知，Apple要求获得“购买”和“还原”按钮(我在应用程序的设置视图中拥有这些按钮)，而在其他视图中，我仅具有“购买”按钮。

当用户单击“购买”按钮并且Apple检测到该用户已经购买了该产品时，他将要求该用户免费恢复此购买(一切都很好)。当用户单击“是”时，就会调用updateTransactions:，并且它始终在case SKPaymentTransactionStatePurchased:上而不是在case SKPaymentTransactionStateRestored:上。

这是为什么 ？有没有办法通过updatedTransactions:将恢复与新购买区分开？

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
    id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
    for(SKPaymentTransaction *transaction in transactions){
        switch (transaction.transactionState){
            case SKPaymentTransactionStatePurchasing: //NSLog(@"Transaction state -> Purchasing");
                //called when the user is in the process of purchasing, do not add any of your own code here.
                break;
            case SKPaymentTransactionStatePurchased:
                //this is called when the user has successfully purchased the package (Cha-Ching!)
                [tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"Purchase" action:@"Purchase Completed!" label:shopNameSelected value:nil] build]];
                [self doGoPremium];
                [MBProgressHUD hideHUDForView:self.view animated:YES];
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                //NSLog(@"Transaction state -> Purchased");
                break;
            case SKPaymentTransactionStateRestored:
                //NSLog(@"Transaction state -> Restored Here");
                //add the same code as you did from SKPaymentTransactionStatePurchased here
                [tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"Purchase" action:@"Purchase Restored" label:shopNameSelected value:nil] build]];
                [self doGoPremium];
                [MBProgressHUD hideHUDForView:self.view animated:YES];
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                //called when the transaction does not finnish
                [MBProgressHUD hideHUDForView:self.view animated:YES];
                if(transaction.error.code != SKErrorPaymentCancelled){
                    //NSLog(@"Transaction state -> Cancelled");
                    //the user cancelled the payment ;(
                    // Add some analytics point.
                    [tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"Purchase" action:@"Purchase Canceled" label:shopNameSelected value:nil] build]];
                }
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
        }
    }
}

最佳答案

购买您已经拥有的东西(尽管UIAlert表示已恢复)会触发SKPaymentTransactionStatePurchased状态。仅在执行以下操作时才会发生SKPaymentTransactionStateRestored状态:

 [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
