iOS7 - 在应用内购买问题

Question

我已将应用程序上传到AppStore给客户。除了In App Purchases，一切正常。他们可以购买产品，但代理方法似乎并未因完整交易而被解雇。虽然，如果按下“恢复”按钮（我制作），他们会收回他们购买的东西，所以我的问题是我需要能够确认他们的产品而不必恢复它。

我的标题文件：

#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>

@interface StartViewController : UIViewController<UIAlertViewDelegate,SKPaymentTransactionObserver, SKProductsRequestDelegate>

@property (strong, nonatomic) IBOutlet UIScrollView *scrollview;

@property (strong, nonatomic) SKProduct *product;
@property (strong, nonatomic) NSString *productID;
@property (strong, nonatomic) SKProductsRequest *request;

@end

    if ([SKPaymentQueue canMakePayments]){
        self.productID = PRODUCT_ID_PRO1; // NSString

                                      initWithProductIdentifiers:

        self.request.delegate = self;
        [self.request start];

        NSLog(@"starting buy!!");

- (void)request:(SKRequest *)request didFailWithError:(NSError *)error{
    UIAlertView *a = [[UIAlertView alloc] initWithTitle:nil message:error.localizedDescription delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil];

我会为此提出赏金，但我必须等待2天。任何一个可以帮助我的人，我真的很感激。
