用于iOS非消费类应用内购买的恢复按钮

问题描述

Apple遗憾地拒绝了我的应用程序没有恢复按钮。我希望为用户提供无缝体验，但存在一些问题。

Apple have unfortunately rejected my app for not having a restore button. I wanted to have a seamless experience for the user but there are some problems.

- (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：

Is the above a good solution? The logic would be:

1. 用户按下按钮删除应用程序内购买。


2. 检查是否用户已经进行了购买（用户必须输入用户名和密码）


3. 如果用户已经购买，则恢复


4. 如果用户有还没有购买，提示付款（用户必须再次输入密码）。

1. User presses button to remove in-app purchase.
2. Check if the user has already made a purchase (user has to enter username and password)
3. If user has already made a purchase, restore
4. If user has not already made a purchase,prompt for payment (user has to enter password again).

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。

The problems with this approach are:1. An additional server call2. User has to enter details twice.

有没有人真正实现了可以演示的恢复按钮？

Has anyone actually implemented a Restore button that they can demonstrate?

推荐答案

无需实现自己的逻辑
只需实现此

No need of implementing your own logicJust implement this

- (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确保交易成功或失败

This will call these delegate methods for transaction success or failure

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