私はアプリ内での統合を持つアプリケーションを持っています。私のアプリでは、有料のアプリを買い、購読するための2つのボタンがあります。ユーザーが購入をクリックすると、リンゴの検証と製品の購入がチェックされます。iOSでアプリを購入して購入した商品が既に購入されているかどうかを確認するにはどうすればよいですか？
これは正常に動作しますが、製品を購入したときに購入ボタンが「完了」に変わり、次回アプリケーションを実行するときにその特定の製品の購入ボタンが表示されなくなります。代わりに「done」ボタンが表示されます。私の問題は、製品が購入されたときに完了ボタンの代わりに購入ボタンが表示されることです。
これは私のコードです：
-(void)checkPurchasedItems
{
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
//Then this delegate Function Will be fired
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions)
{
NSString *productID = transaction.payment.productIdentifier;
NSLog(@"%@",productID);
}
}
// called when a transaction has failed
- (void)failedTransaction:(SKPaymentTransaction *)transaction
{
if (transaction.error.code != SKErrorPaymentCancelled)
{
// error!
[self finishTransaction:transaction wasSuccessful:NO];
if (transaction.error.code == SKErrorClientInvalid) {
//[self showAlert:@"In-App Purchase" withMessage:INVALID_CLIENT];
}
else if (transaction.error.code == SKErrorPaymentInvalid) {
//[self showAlert:@"In-App Purchase" withMessage:PAYMENT_INVALID];
}
else if (transaction.error.code == SKErrorPaymentNotAllowed) {
//[self showAlert:@"In-App Purchase" withMessage:PAYMENT_NOT_ALLOWED];
}
else if (transaction.error.code == SKErrorPaymentCancelled) {
// [self showAlert:@"In-App Purchase" withMessage:@"This device is not allowed to make the payment."];
NSLog(@"User Cancellation.");
}
else {
// SKErrorUnknown
NSLog(@"Unknown Reason.");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Transaction Status" message:@"Transaction Failed due to unknown reason" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
}
else {
// this is fine, the user just cancelled, so don’t notify
// UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Transaction Status" message:@"Transaction failed due to some reason" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
// [alert show];
// return;
//[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
