How to store and fetch the response of in-app purchase in ios?

I have implemented in-app purchase in my project. The implementation worked well but I have a problem to store a response.

I unlocked the button and when I go through in-app purchase the button will be unlocked the response becomes true.

But when I go back the class from which I came this class, and jump back to this class again, I got the button locked again because I am not able to store response.

I am doning this:

.h file
bool isPurchased;






 -(void) successfulPurchase:(EBPurchase*)ebp restored:(bool)isRestore identifier:(NSString*)productId receipt:(NSData*)transactionReceipt
{
NSLog(@"ViewController successfulPurchase");

// Purchase or Restore request was successful, so...
// 1 - Unlock the purchased content for your new customer!
// 2 - Notify the user that the transaction was successful.

if (!isPurchased)
{
   // If paid status has not yet changed, then do so now. Checking
   // isPurchased boolean ensures user is only shown Thank You message
   // once even if multiple transaction receipts are successfully
   // processed (such as past subscription renewals).

   isPurchased = YES;


   if([[[NSUserDefaults standardUserDefaults] objectForKey:@"isPurchased"]     isEqualToString:@"true"]){

isPurchased = YES;
// do something

}
else{
isPurchased = NO;
//isFailed = NO;
 // do something  
}


   //-------------------------------------

   // 1 - Unlock the purchased content and update the app's stored settings.

   //-------------------------------------

   // 2 - Notify the user that the transaction was successful.

   NSString *alertMessage;

   if (isRestore) {
       // This was a Restore request.
       alertMessage = @"Your purchase was restored and the Game Levels Pack is now  unlocked for your enjoyment!";

   } else {
       // This was a Purchase request.
       alertMessage = @"Your purchase was successful and the Game Levels Pack is now   unlocked for your enjoyment!";


       //  if (my_unlock_button == TRUE) {
       buyButton.hidden=YES;                   // These are the buttons  I unlocked
       buybutton1.hidden=YES;                 // These are the buttons   I unlocked

       //}

   }

   UIAlertView *updatedAlert = [[UIAlertView alloc] initWithTitle:@"Thank You!"  message:alertMessage delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
   [updatedAlert show];
   [updatedAlert release];
}
}

how to store and fetch the response so that I can check the response?

Any Idea or suggestions from experts would be highly welcome.

I have developed storekit for non consumable product. You can try it. ;)

Happy coding!

You need to implement it like.

When the purchase is successful set a bool in NSUserDefaults like:

[[NSUserDefaults standardUserDefaults] setBool:YES ForKey:@"isPurchased"];

In the viewDidLoad of the class, write like:

if([[NSUserDefaults standardUserDefaults] boolForKey:@"isPurchased"])
{
   //Enable/show the button
}
else
{
   //disable/hide button
}

This is a nice tutorial, please refer it also
