Question

我正在关注this In App Purchase tutorial，我可以看到我在iTunesConnect IAP内容中发布的产品说明和标题。但是，当我点击buyButton时，我收到了Thread 1:EXC_BAD_ACCESS(code=1, address=0xc)错误：

- (IBAction)buyProduct:(id)sender {
    SKPayment *payment = [SKPayment paymentWithProduct:_product];//<-- This line course the error.
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

有人建议我在_product之前和之后对buyButton进行检查，结果确实不同：

-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{

    NSArray *products = response.products;

    if (products.count != 0)
    {
        _product = products[0];
        _buyButton.enabled = YES;
        _productTitle.text = _product.localizedTitle;
        _productDescription.text = _product.localizedDescription;
        NSLog(@"productsRequest: %@", _product);
        //NSLog(@"productsRequest: %@", _product.localizedTitle);
    } else {
        _productTitle.text = @"Product not found";
    }

    products = response.invalidProductIdentifiers;

    for (SKProduct *product in products)
    {
        NSLog(@"Product not found: %@", product);
    }
}

- (IBAction)buyProduct:(id)sender {
    NSLog(@"Product title: %@", _product);//<-- this give different result from productsRequest function.

}

从-(void)productsRequest开始，

productsRequest: <SKProduct: 0x17e8e3f0>

来自- (IBAction)buyProduct，我得到

Product title: #<CGRegion 0x17e8e3f0 empty>

有时随机的长期结果：

Product title: Length 11 (2 blocks, 1 used, block 0 is at 0)
 11 0x165ae790 {
    NSColor = "UIDeviceRGBColorSpace 0.838794 0.39337 1 1";
    NSFont = "<UICTFont: 0x165ae010> font-family: \".HelveticaNeueInterface-M3\"; font-weight: normal; font-style: normal; font-size: 17.00pt";
    NSParagraphStyle = "Alignment 1, LineSpacing 0, ParagraphSpacing 0, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 0/0, LineHeightMultiple 0, LineBreakMode 4, Tabs (\n    28L,\n    56L,\n    84L,\n    112L,\n    140L,\n    168L,\n    196L,\n    224L,\n    252L,\n    280L,\n    308L,\n    336L\n), DefaultTabInterval 0, Blocks (null), Lists (null), BaseWritingDirection -1, HyphenationFactor 0, TighteningFactor 0, HeaderLevel 0";
    NSShadow = "NSShadow {0, -1} color = {(null)}";
}

知道如何解决这个问题？
