我已在我的应用中实施应用内购买。我的问题是当新用户点击恢复按钮时，完成1个循环后进程没有停止并反复执行。执行3到4次后，进程停止。
我想在新用户没有购买任何交易时立即停止处理。
这是我的IAP课程的代码。
- (void)restorePurchases
{
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error
{
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
[ProgressHUD dismiss];
}
- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
[ProgressHUD dismiss];
}
// Sent when transactions are removed from the queue (via finishTransaction:).
- (void)paymentQueue:(SKPaymentQueue *)queue removedTransactions:(NSArray *)transactions
{
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
[ProgressHUD dismiss];
}
// Called when the transaction status is updated
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchasing:
[self transactionStart:transaction];
break;
case SKPaymentTransactionStatePurchased:
[self transactionComplete:transaction];
[[SKPaymentQueue defaultQueue]
finishTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self transactionFailed:transaction];
[[SKPaymentQueue defaultQueue]
finishTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
{
[self transactionRestored:transaction];
[[SKPaymentQueue defaultQueue]
finishTransaction:transaction];
break;
}
default:
break;
}
}
}
#pragma mark - Local method for mange transactions -
-(void)transactionStart:(SKPaymentTransaction *)transaction
{
if([self.delegate respondsToSelector:@selector(startPayment:)]){
[self.delegate startPayment:transaction];
}
}
-(void)transactionComplete:(SKPaymentTransaction *)transaction
{
if([self.delegate respondsToSelector:@selector(completePayment:)]){
[self.delegate completePayment:transaction];
}
}
-(void)transactionFailed:(SKPaymentTransaction *)transaction
{
if ([self.delegate respondsToSelector:@selector(failedPayment:)]) {
[self.delegate failedPayment:transaction];
}
}
-(void)transactionRestored:(SKPaymentTransaction *)transaction
{
if([self.delegate respondsToSelector:@selector(restoredPayment:)]){
[[AppDelegate sharedAppDelegate].arrayConacatResponse addObject:[NSString stringWithFormat:@"transactionRestored method "] ];
[self.delegate restoredPayment:transaction];
}
}
In Restore payment method
- (void)restoredPayment:(SKPaymentTransaction *)transactions
{
if ([transactions.payment.productIdentifier isEqualToString:monthlySubscription]) {
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSError *receiptError;
BOOL isPresent = [receiptURL checkResourceIsReachableAndReturnError:&receiptError];
if (isPresent)
{
NSData *receiptData = [[NSData alloc] initWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]];
BOOL isSubscriptionPeriodValid = [[DataBase sharedInstance] getSubscriptionStatusFromAppleWithReceipt:receiptData];
if (isSubscriptionPeriodValid)
{
[self removeFromSuperview];
}else{
// Here I want to stop
[CommonUtilities showAlertWithTitle:@"" Message:@"You have no transaction to restore."];
}
}
}
[ProgressHUD dismiss];
}
