Tôi có một ứng dụng tích hợp ứng dụng trong đó. Trong ứng dụng của tôi, tôi có hai nút để mua ứng dụng trả phí và đăng ký. Khi người dùng nhấp vào mua nó đi kiểm tra xác nhận táo và mua sản phẩm.Làm thế nào để kiểm tra xem một sản phẩm đã được mua bằng cách sử dụng trong mua ứng dụng trong iOS?
Thao tác này hoạt động đúng cách nhưng khi sản phẩm được mua nút mua của tôi sẽ thay đổi thành 'đã hoàn thành' và khi ứng dụng lần sau, nút mua sẽ không hiển thị cho sản phẩm cụ thể đó. Thay vào đó, nút 'thực hiện' sẽ được hiển thị. Vấn đề của tôi là khi một sản phẩm được mua nút mua được hiển thị thay vì nút thực hiện.
Đây là mã của tôi:
-(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];
}
