用于iOS非消费类应用内购买的恢复按钮

不幸的是，由于没有恢复按钮，Apple拒绝了我的应用程序。 我希望为用户提供无缝体验，但存在一些问题。 

- (void)purchaseProUpgrade { [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; // User is prompted for iTunes username and password here (1) [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; } // Then this delegate Function Will be fired - (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue { if( queue.transactions.count == 0 ) { [self setUpgradeProductId]; // User is prompted for iTunes username and password here (2) SKPayment *payment = [SKPayment paymentWithProductIdentifier:kInAppPurchaseProUpgradeProductId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; }else { [[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerTransactionSucceededNotification object:self userInfo:NULL]; } }

以上是一个很好的解决方案吗？ 逻辑是：

  1. 用户按下按钮即可删除应用内购买。
  2. 检查用户是否已经购买（用户必须输入用户名和密码）
  3. 如果用户已购买，请恢复
  4. 如果用户尚未进行购买，则提示付款（用户必须再次输入密码）。

这种方法的问题是：1。额外的服务器调用2.用户必须输入两次详细信息。

有没有人真正实现了可以演示的“恢复”按钮？

无需实现自己的逻辑只需实现它 

 - (IBAction)restorePreviousTransaction:(id)sender { [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; }

这将调用此方法 

  - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions { case SKPaymentTransactionStateRestored: if ([self respondsToSelector:@selector(restoreTransaction:)]) { [self restoreTransaction:transaction]; return; }

这将调用这些委托方法以实现事务成功或失败 

 - (void)restoreTransaction:(SKPaymentTransaction *)transaction -(void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error -(void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue

将此代码添加到已添加还原按钮的页面： 

 - (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error { NSLog(@"%@",error); } // Call This Function - (void) checkPurchasedItems { [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; } //Then this delegate Function Will be fired - (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue { purchasedItemIDs = [[NSMutableArray alloc] init]; NSLog(@"received restored transactions: %i", queue.transactions.count); for (SKPaymentTransaction *transaction in queue.transactions) { NSString *productID = transaction.payment.productIdentifier; [purchasedItemIDs addObject:productID]; NSLog(@"%@",purchasedItemIDs); } }

Apple拒绝使用In App Purchase的应用程序，该应用程序没有恢复购买按钮。 在应用视图中，添加还原按钮。 然后在In App Purchase帮助程序类中，添加以下方法： 

 - (void)restoreCompletedTransactions { [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; }

现在从按钮单击操作调用此方法，它将恢复以前的购买。 

 *- (IBAction)restorePreviousTransaction:(id)sender { [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; } delegate method call: - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions { case SKPaymentTransactionStateRestored: if ([self respondsToSelector:@selector(restoreTransaction:)]) { [self restoreTransaction:transaction]; return; } - (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue { purchasedItemIDs = [[NSMutableArray alloc] init]; NSLog(@"received restored transactions: %i", queue.transactions.count); for (SKPaymentTransaction *transaction in queue.transactions) { NSString *productID = transaction.payment.productIdentifier; [purchasedItemIDs addObject:productID]; NSLog(@"%@",purchasedItemIDs); } }*
