恢复应用内购买问题

Question

我已成功实施我的广告移除非消耗性应用内购买。我读到我的应用程序中还必须有一个“恢复”按钮。在过去的两天里，我尝试实现一个恢复功能，阅读了 stackoverflow 上的所有其他帖子，但对我没有任何帮助。当按下恢复按钮时，它会按预期要求电子邮件和密码，但即使我以前没有在该 Apple ID 上购买过产品，它仍然会恢复它。下面是我正在使用的代码。任何帮助将不胜感激！

- (IBAction)RestoreProduct:(id)sender {


[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

NSLog(@"Calling Restore");

_restoreButton.enabled = NO;

_productTitle.text = [NSString stringWithFormat:@"Checking for product"];


}




- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"Calling First Function");
NSMutableArray *purchasedItemIDs = [[NSMutableArray alloc] init];

NSLog(@"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions)
{
    NSString *productID = transaction.payment.productIdentifier;
    [purchasedItemIDs addObject:productID];
    NSLog(@"This Part");
    [self unlockFeature];
    _productTitle.text = [NSString stringWithFormat:@"Purchase Restored!"];
}

}




- (void)paymentQueue:(SKPaymentQueue*)queue restoreCompletedTransactionsFailedWithError:    (NSError*)error
{
NSLog(@"error");
}

编辑。

好的，这是我从恢复按钮到@end 的所有代码。

- (IBAction)RestoreProduct:(id)sender {


[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

NSLog(@"Calling Restore");

_restoreButton.enabled = NO;

_productTitle.text = [NSString stringWithFormat:@"Checking for product"];


}

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"Calling First Function");
NSMutableArray *purchasedItemIDs = [[NSMutableArray alloc] init];

NSLog(@"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions)
{
    NSString *productID = transaction.payment.productIdentifier;
    [purchasedItemIDs addObject:productID];
    NSLog(@"This Part");

}

}

- (void)paymentQueue:(SKPaymentQueue*)queue restoreCompletedTransactionsFailedWithError:    (NSError*)error
{
NSLog(@"error");
}

#pragma mark -
#pragma mark SKPaymentTransactionObserver

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

for (SKPaymentTransaction *transaction in transactions)
{
    switch (transaction.transactionState) {
        case SKPaymentTransactionStatePurchased:
            [self unlockFeature];
            _productTitle.text = [NSString stringWithFormat:@"Purchase Complete!"];
            [[SKPaymentQueue defaultQueue]
             finishTransaction:transaction];
            break;

        case SKPaymentTransactionStateFailed:
            NSLog(@"Transaction Failed");
            [[SKPaymentQueue defaultQueue]
             finishTransaction:transaction];
            break;

        default:
            break;
    }
}
}

-(void)unlockFeature
{
_buyButton.enabled = NO;
[_buyButton setTitle:@"Purchased"
            forState:UIControlStateDisabled];
[_homeViewController enableLevel2];
}

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
_buyButton.enabled = NO;
_restoreButton.enabled = NO;
}

- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

我有一个按钮调用

+ (void)restoreABC
{
    NSLog(@"Restore Purchases");
   [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

我猜你的问题是你也在打电话

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

就在上面：

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

删除第一行，你可能就可以开始了。

编辑： 根据下面的 cmets，听起来 [self unlockfeature] 行是罪魁祸首:-)

编辑#2：

添加

    case SKPaymentTransactionStateRestored:
        NSLog(@"Feature Previously Purchased");
        [self unlockFeature];
        break;

到

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