I'm programming StoreKit into my iPhone app. I can't seem to be able to intercept the buy item dialog wait time either before or after pressing the button to purchase the item. Pretty much what I want is an indicator on the screen before the buy dialog appears and after, but before the purchased item is unlocked. I don't want my users being hung up on the screen, not knowing if their purchase went through.

Also, if I'm not displaying a store, just one predictable item, do I need to requestProductData? Anything to make the wait time as less as possible would be good.

One last thing: In the - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions method, if I show an alertView if the case SKPaymentTransactionStateFailed: is fulfilled, I keep on getting multiple calls, even if the purchase is done once.

Thanks!

Please help with anything you can (just trying to learn my iPhone programming).

对于您在处理缓慢的过程中关于活动视图的第一个问题。

您可以在 Payment Queue 中截取“SKPaymentTransactionStatePurchasing 状态以建立一个带有活动指示符的 Alert View。在您完成处理后关闭处于 Purchased、Restored 和 Failed 状态的 View。StoreKit 生成的 AlertViews 将使这个消失并在整个过程中根据需要重新出现。

case SKPaymentTransactionStatePurchasing:
                purchaseActivityIndicator = [[UIAlertView alloc] initWithTitle:@"Processing purchase" message:@"Please wait..." delegate:self cancelButtonTitle:nil otherButtonTitles:nil,nil];
                UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
                [activity setFrame:CGRectMake(121.0f, 80.0f, 36.0f, 36.0f)];
                [purchaseActivityIndicator addSubview:activity];
                [activity startAnimating];
                [activity release];
                [purchaseActivityIndicator show];
                [purchaseActivityIndicator release];
                break;

对于第二个问题，我在应用程序启动时启动商店项目的加载，以便在用户到达商店时准备好它们。由于它们是异步加载的，因此它们应该在用户进入商店视图时准备就绪。

不确定最后一个问题。
