Transaction isn't being completed - ios

Question

I want the payment transaction to complete once the download transaction has completed but when the download finishes for some reason the transaction state is not completed. Do i have to put the payment transaction back in the queue after the download is complete here is more code.
- (void)buyProduct:(SKProduct *)product {
NSLog(#"Buying %#...", product.productIdentifier);
SKPayment * payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for (SKPaymentTransaction * transaction in transactions) {
if(transaction.downloads){
[[SKPaymentQueue defaultQueue] startDownloads:transaction.downloads];
}else{
switch (transaction.transactionState){
case SKPaymentTransactionStatePurchased:
[self completeTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];
default:
break;
}
}
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedDownloads:(NSArray *)downloads;
{
for (SKDownload *download in downloads) {
if (download.downloadState == SKDownloadStateFinished) {
[self processDownload:download]; //handle download
// now we're done
NSLog(#"Download finished");
[[SKPaymentQueue defaultQueue] finishTransaction:download.transaction];
//Do I need to add the payment transaction back in the queue? Im worried the payment will go through twice?
} else if (download.downloadState == SKDownloadStateActive) {
NSString *productID = download.contentIdentifier; // in app purchase identifier
NSTimeInterval remaining = download.timeRemaining; // secs
float progress = download.progress; // 0.0 -> 1.0
NSLog(#"Product ID:%#", productID);
NSLog(#"Time remaining: %f", remaining);
NSLog(#"Download progress percent: %f", progress);
} else { // waiting, paused, failed, cancelled
NSLog(#"Warn: not handled: %d", download.downloadState);
}
}
}
These are my methods I created for my transaction state if it matters at all? None of them are being executed anyways so I don't think it matter but here it is.
- (void)completeTransaction:(SKPaymentTransaction *)transaction {
NSLog(#"completeTransaction...");
[self provideContentForProductIdentifier:transaction.payment.productIdentifier];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
- (void)restoreTransaction:(SKPaymentTransaction *)transaction {
NSLog(#"restoreTransaction...");
[self provideContentForProductIdentifier:transaction.originalTransaction.payment.productIdentifier];
if(transaction.downloads){
[[SKPaymentQueue defaultQueue] startDownloads:transaction.downloads];
NSLog(#"Download exists");
}else{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
}
- (void)failedTransaction:(SKPaymentTransaction *)transaction {
NSLog(#"failedTransaction...");
if (transaction.error.code != SKErrorPaymentCancelled)
{
NSLog(#"Transaction error: %#", transaction.error.localizedDescription);
}
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
