如何在等待应用内购买商店加载后停止 uiactivityindicator

Question

我认为其中之一可以做到这一点，但没有一个被调用 -_-

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    NSLog(@"flag paymentQueue");

// spinner.hidden=YES; //这去哪儿了？

    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchasing:
            //    [self stillPurchasing]; // this creates an alertView and shows
                NSLog(@"flag SKPaymentTransactionStatePurchasing");

                break;
            case SKPaymentTransactionStatePurchased:
                NSLog(@"flag SKPaymentTransactionStatePurchased");

                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                NSLog(@"flag SKPaymentTransactionStateFailed");

                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"flag SKPaymentTransactionStateRestored");

                [self restoreTransaction:transaction];
           //     spinner.hidden=YES;
                break;

谢谢！！！

Answer 1

您可以通过以下方法隐藏微调器 -

    - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
      [target hideSpinner];
     }

Answer 2

应该不错。在以下 3 种情况下，您应该隐藏微调器：
- SKPaymentTransactionStatePurchased
- SKPaymentTransactionStateFailed
- SKPaymentTransactionStateRestored

您检查过您的代表吗？
你的类应该实现以下委托方法：
-> SKPaymentTransactionObserver

我的声明如下：
@interface InAppPurchaseStoreManager : NSObject
