ios - 崩溃日志，当从 iap 获取产品列表时

Question

我从我的应用程序用户那里得到了崩溃日志。这个用户想要打开 IAP 产品列表，然后我的应用程序崩溃了。我查看了日志和我的代码。我不知道为什么我的应用会崩溃。

我重新符号化了日志，发现了一些线索

[IAPManager productsRequest:didReceiveResponse:] (IAPManager.mm:115)

第115行是

wrapProduct->setLocalizedTitle(ccs([product.localizedTitle UTF8String]));

下面是方法代码

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

    //NSArray *myProducts = response.products;
    NSArray *myProducts = response.products;
    //NSLog(@"产品Product ID:%@",response.invalidProductIdentifiers);
    //NSLog(@"产品付费数量: %d", [myProducts count]);
    // populate UI
    IAPClient::sharedIAPClient()->getProductList()->removeAllObjects();

    myProducts=[myProducts sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
        SKProduct *p1=obj1;
        SKProduct *p2=obj2;
        return [p1.price compare:p2.price];
        //        if ( [p1.price compare:p2.price] ) {
        //            return (NSComparisonResult)NSOrderedAscending;
        //        } else {
        //            return (NSComparisonResult)NSOrderedDescending;
        //        }
    }];
    for(SKProduct *product in myProducts){
        Product *wrapProduct=new Product;
        wrapProduct->setProductIdentifier(ccs([product.productIdentifier UTF8String]));
        wrapProduct->setLocalizedTitle(ccs([product.localizedTitle UTF8String]));
        wrapProduct->setLocalizedDescription(ccs([product.localizedDescription UTF8String]));
        wrapProduct->setLocalizedPrice(ccs([[product localizedPrice] UTF8String]));
        wrapProduct->setPrice([product.price floatValue]);
        IAPClient::sharedIAPClient()->getProductList()->addObject(wrapProduct);
        wrapProduct->release();
    }

    [request autorelease];
    IAPClient::sharedIAPClient()->gotProductData();
}

我对此一无所知。谁能给我一些建议？

Apple 正在为 product.localizedTitle 返回一个 nil 值。我们也在多款游戏中看到了这一点。这是昨晚才开始发生的新(坏!)行为。
