[self completeTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];

break;
}
};
}

define kMDPulseSubscriptionProductIdentifier #"Your Product ID here...."
SKPaymentTransactionOBserver:
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing:

break;
case SKPaymentTransactionStatePurchased:

[self completeTransaction:transaction];
NSError* error;
NSDictionary* jsonDict = [NSJSONSerialization

NSLog(#"JSON Receipt: %#",jsonDict);
[[NSUserDefaults standardUserDefaults] setObject:jsonDict forKey:#"A"];
NSLog(#"Purchase was a Success.....");
}
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
NSLog(#"Purchase cancelled");

Answer 2

When you call this method for restoring
-(void)restoreCompletedTransactions
{
NSLog(#"Restore Tapped in transaction process");
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
//Then this delegate Function Will be fired
-(void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
alert = [[UIAlertView alloc] initWithTitle:#"IN APP PURCHASE" message:#"Processing" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
UIActivityIndicatorView *progress= [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125, 50, 30, 30)];
progress.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
[alert addSubview:progress];
[progress startAnimating];
[alert show];
[progress release];
for (SKPaymentTransaction *transaction in queue.transactions)
{
// Use this Commented code to Log and check details about your Products
/**
NSLog(#"%d",queue.transactions.count);
NSMutableArray * purchasedItemIDs = [[NSMutableArray alloc] init];
for (SKPaymentTransaction *transaction in queue.transactions)
{
NSString *productID = transaction.payment.productIdentifier;
[purchasedItemIDs addObject:productID];
NSLog(#"%#",purchasedItemIDs);
}*/
if( queue.transactions.count == 0 ) {
// User hav't purchased yet.
NSLog(#"User hav't purchased yet.");
UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:#"Restore" message:#"You have not purchased yet"
delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:Nil, nil];
[alertView show];
[alertView release];
}else {
// Upgrade to Full version.
NSLog(#"Upgrade to Full version.");
// Do stuffs here
//finally finish transaction
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
}
[alert dismissWithClickedButtonIndex:0 animated:YES];
}
Hope this helps!!
