在应用内购买购买后，ios App立即崩溃

Question

基本上，我处境非常糟糕。我们的团队使用新功能成功开发和发布新版应用程序，用户可以购买（应用程序内购买）。 因此，我们已经使用iTunes测试用户测试了所有新功能，并且一切都运行良好，但是，当我们在appStore中看到发布版本与真正的iTunes用户时，存在一个巨大的问题。用户只需按下按钮即可购买应用程序内购买，在他输入其帐户密​​码并接受购买此新信息后。不幸的是，应用程序在此操作后每次都会崩溃。此后没有任何行动。

基本上，对于应用内购买，我使用MKStoreKit。 所以，我想提出以下行动的代码：

- (IBAction)buyNewRequest:(id)sender
{

id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"uiAction"
                                                          action:@"Обработчик нажатия кнопки"
                                                           label:@"Кнопка - отправить запрос. Экран - запроса кредитной истории бки"
                                                           value:[NSNumber numberWithInt:100]] build]];

if ([self checkValidaionTextFields])
{
    [DejalBezelActivityView activityViewForView:self.view withLabel:@"Подождите..."].showNetworkActivityIndicator = YES;
    self.sendButton.enabled = NO;
    [[MKStoreManager sharedManager] buyFeature:@"ru.financemart.nbki"
                                    onComplete:^(NSString* purchasedFeature,
                                                 NSData* purchasedReceipt,
                                                 NSArray* availableDownloads)

         self.sendButton.enabled = YES;
         [DejalBezelActivityView removeViewAnimated:YES];

}
}

因此，在用户接受应用内购买后，您可以看到我们服务器的POST请求（[self.unicomService postNBKIRequestWithName :)，但我们的服务器数据库日志中没有请求，因此应用程序在此代码之前崩溃。但是，没有代码字符串可以崩溃。
