Restore Purchase for iAP shows alert on app startup

I have 2 problems when I added the restore method for iAP...

Problem 1: Everytime I open my app a iTunes alert comes up and ask if I wanna login to the iTunes Store. This happens since I add the following restore method:

- (IBAction)Restore:(id)sender {
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

Now, even when I remove the restore method the alert keeps on coming at startup. It seems that Apple already connects with iTunes at the startup of the app. I wanna make this only when a user hits the purchase or restore button. I read several things on StackOverflow that you have to add something in your AppDelegate so that the app is not connecting automatically but with still no luck.

Problem 2: When testing the iAP on my phone and hit the restore button the item can be restored, even if I didn't purchased it before. Is this normal when testing the restore function with a test account? You should say that Apple have to show alert that the item has never been purchased and cannot be restored?

Can someone please guide me step-by-step with this to make it work?

Thanks in advance.

The code:

- (IBAction)Restore:(id)sender {
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

-(void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
    [self unlockFeature];
}

#pragma mark -
#pragma mark SKPaymentTransactionObserver

-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchased:
                [self unlockFeature];
                [[SKPaymentQueue defaultQueue]
                 finishTransaction:transaction];
                break;

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

            default:
                break;
        }
    }
}

I had something similar to your first problem whilst I was adding IAP's to an app. It turned out that whilst I had been going through testing it and changing things I had got a backlog of pending transactions, so every time I opened the app it was trying to finish those off. If you sign in, let it do anything it needs, close, reopen and repeat I managed to catch up and it stopped asking me to sign in every time. It might be worth giving that a shot. (I'm trying to dig out the question that I got this answer from).

It is restoring the IAP because you are calling [self unlockFeature] when the restore transaction queue finish's even if it hasn't restored anything:

-(void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
    [self unlockFeature];
}

You should remove the unlockFeature call and sort the transaction handling in the 

-paymentqueue:updatedtransactions:

Add this to the switch:

case SKPaymentTransactionStateRestored:
        [self unlockFeature];
        [[SKPaymentQueue defaultQueue]
        finishTransaction:transaction];
        break;
