【问题描述】：

我添加了一个 UIAlertView，它具有 UIActivityIndi​​catior 作为我的应用程序的子视图。 此 alertView 仅在购买进行时显示。我以这种方式将警报视图放在我的 StoreObserver 中：

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions 
   for (SKPaymentTransaction *transaction in transactions)
    

       switch (transaction.transactionState)
       
        case SKPaymentTransactionStatePurchasing:
                [self stillPurchasing]; // this creates an alertView and shows
                break;

        case SKPaymentTransactionStatePurchased:
                [self completeTransaction:transaction];         
                break;

        case SKPaymentTransactionStateFailed:           
               [self failedTransaction:transaction];
               break;

        case SKPaymentTransactionStateRestored:
              [self restoreTransaction:transaction];
              break;

        default:
            break;
               
    

- (void) stillPurchasing 

UIAlertView *alert  = [[UIAlertView alloc]initWithTitle: @"In App Purchase" message: @"Processing your purchase..." delegate: nil cancelButtonTitle: nil otherButtonTitles: nil];
self.alertView = alert;
[alert release];

 UIActivityIndicatorView *ind = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle: UIActivityIndicatorViewStyleWhiteLarge];
 self.indicator = ind;
 [ind release];
 [self.indicator startAnimating];

 [self.alertView addSubview: self.indicator];
 [self.alertView show];

当我点击我的购买按钮时，这个 UIAlertView 与我的 UIActivityIndi​​cator 一起显示。但是当交易完成时，alertView 仍然在视图的顶部，并且指示器是唯一被删除的。我的问题是我应该如何释放 alertView？或者我应该在哪里/何时发布它。

我添加了这些命令以在这些情况下释放我的 alertView 和 Indicator： 案例 SKPaymentTransactionStatePurchased： 案例 SKPaymentTransactionStateFailed： 案例SKPaymentTransactionStateRestored：

[self.indicator stopAnimating];
[self.indicator removeFromSuperview];
[self.alertView release];
[self.indicator release]; 

我只添加了 alertView 以显示购买仍在进行中。任何向用户创建任何反馈的建议都将感谢我..

谢谢

【参考方案1】：

要删除警报视图，请使用

[alertView dismissWithClickedButtonIndex:0 animated:YES];
