iPhone Store Kit“无法连接到 itunes 商店”无法连接到 itunes 商店”

Question

我已经在我的 iOS 应用程序中实现了 storeKit，这是代码：

-(IBAction)Purchase:(id)sender{
SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"month"];
[[SKPaymentQueue defaultQueue]addTransactionObserver:self];
[[SKPaymentQueue defaultQueue]addPayment:payment];
}


-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    SKProduct *VailProduct = nil;
    int count = [response.products count];
    if (count>0) {
        VailProduct = [response.products objectAtIndex:0];
    } else if (!VailProduct){
        UIAlertView *theAlert = [[UIAlertView alloc]initWithTitle:@"LOG" message:@"No Products Are Availble!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        [theAlert show];
        [theAlert release];

    }
    
}

-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
    for (SKPaymentTransaction *transaction in transactions) {
        switch (transaction.transactionState) {
        case SKPaymentTransactionStatePurchasing:
                
                break;
                case SKPaymentTransactionStatePurchased:
                [self EnableEmergencyCenter];
                [[SKPaymentQueue defaultQueue]finishTransaction:transaction];
                break;
                
                case SKPaymentTransactionStateRestored:
                [[SKPaymentQueue defaultQueue]finishTransaction:transaction];
                break;
                
                case SKPaymentTransactionStateFailed:
                if (transaction.error.code != SKErrorPaymentCancelled) {
                    UIAlertView *theAlert = [[UIAlertView alloc]initWithTitle:@"LOG" message:[NSString stringWithFormat:@"%@",transaction.error] delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
                    [theAlert show];
                    [theAlert release];

                }
                [[SKPaymentQueue defaultQueue]finishTransaction:transaction];
                break;
        }
    }
}

这是在 viewDidLoad 上出现的：

if ([SKPaymentQueue canMakePayments])
{
     // Display a store to the user.
    UIAlertView *theAlert = [[UIAlertView alloc]initWithTitle:@"LOG" message:@"Device Can Make Payments!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
    [theAlert show];
    [theAlert release];
    
    SKProductsRequest *ProductRequst = [[SKProductsRequest alloc]initWithProductIdentifiers:[NSSet setWithObject:@"month"]];
    ProductRequst.delegate = self;
    [ProductRequst start];
}
else {
     // Warn the user that purchases are disabled.
    UIAlertView *theAlert = [[UIAlertView alloc]initWithTitle:@"LOG" message:@"Device Can't Make Payments!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
    [theAlert show];
    [theAlert release];
}

产品标识符是正确的，但我不断收到从 switch 语句调用的错误

    case SKPaymentTransactionStateFailed:
        if (transaction.error.code != SKErrorPaymentCancelled) {
            UIAlertView *theAlert = [[UIAlertView alloc]initWithTitle:@"LOG" message:[NSString stringWithFormat:@"%@",transaction.error] delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [theAlert show];
            [theAlert release];

尝试以下操作：

• 创建一个新的配置文件，安装它并用它签署您的应用程序。有时，当您编辑旧的个人资料时，它们不会真正更新，因此付款流程将无法进行。
• 如果您正确收到产品并且之前安装了应用程序的 iTunes 版本，则需要从设备中删除该应用程序并通过 XCode 安装它。

这也可以帮助您

购买失败是因为交易在技术上失败，这并不是特别因为无法连接......这可能是由于多种原因造成的。仔细检查产品标识符是否正确。我认为您的问题很可能是您没有使用链接到您的应用程序所使用的应用程序 ID 的开发证书来签署您的应用程序。在 iTunes Connect 中，您的应用程序链接到哪个应用程序 ID？它需要是该应用程序特有的应用程序 ID（即 com.ChillySky.InAppPurchaseApp，而不是 com.ChillySky.*），没有通配符！此外，您需要生成特殊的开发证书才能在您的设备上测试此应用程序。它必须链接到正确的应用程序 ID！如果其中任何一项不正确，您的应用内购买将无法完成。这对我来说是最大的问题。
