Inapp Purchase is succeeded but content is not unlock in iPhone app.. Why?

In My iphone app i have used In App purchase. All the things are working and the contents are in Resource folder. After successful transaction i have used a Sql Query to insert data in Sqlite database. I have Uploaded this app in App Store and find that after successful transaction the payment is taken from users but the content is not inserted in database and not Showed in app. Please help me. i am stressed on this Point. Due to this i have removed my app form App Store.

In this code after successful finding list of In App Purchases i am using method

For better Understanding i am putting my Some code here:

- (void)insertNewObject {

    // Create a new instance of the entity managed by the fetched results controller.
    NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext];

    // Save the context.
    NSError *error = nil;
 开发者_JAVA技巧   if (![context save:&error]) {
        /*
         Replace this implementation with code to handle the error appropriately.

         abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button.
         */
        // NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        abort();
    }
}


-(void)updateObject {
    NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext];

    // Save the context.
    NSError *error = nil;
    if (![context save:&error]) {

        abort();
    }
}

Please have a look and tell me where should i insert data in database so that i will able to provide data to users after Successful in app Purchase.

Thanks in Advance

You should implement your unlocking functionality into the payment observer, right after you receive confirmation that the payment is all right. Your implementation of the observer is kinda strange, I guess it's not working.

EDIT:

your observer class

#import Foundation/Foundation.h
#import StoreKit/StoreKit.h


@interface InAppPurchaseObserver : NSObject  {

}

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

@end

#import "InAppPurchaseObserver.h"

    for(SKPaymentTransaction *transaction in transactions) {
        switch (transaction.transactionState) {

            case SKPaymentTransactionStatePurchasing:
                // Item is still in the process of being purchased
                NSLog(@"Processing!!!");
                break;

            case SKPaymentTransactionStatePurchased:
                // Item was successfully purchased!

                // --- UNLOCK FEATURE OR DOWNLOAD CONTENT HERE ---
                // The purchased item ID is accessible via 
                // transaction.payment.productIdentifier



                // After customer has successfully received purchased content,
                // remove the finished transaction from the payment queue.
                [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
                break;

                // After customer has restored purchased content on this device,

                }
