ios - 类型 skproduct 的无效转换类型 nsmutablearray - ios

Question

我收到“无效的转换类型 nsmutablearray 以键入 skproduct”错误。当我尝试将产品添加到我的 uitableview 时。这是我正在使用的代码...

初始化

SKProduct *product1 = [[InAppPurchaseManager sharedInAppManager] getLevelUpgradeProduct];
        SKProduct *product2 = [[InAppPurchaseManager sharedInAppManager] getPlayerUpgradeOne];
        SKProduct *product3 = [[InAppPurchaseManager sharedInAppManager] getPlayerUpgradeTwo];

        _products = [[[NSMutableArray alloc] initWithObjects:product1, product2, product3, nil] autorelease];





- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
......
        SKProduct *product = (SKProduct*) _products[indexPath.row]; // error 
        cell.textLabel.text = product.localizedTitle;
        [_priceFormatter setLocale:product.priceLocale];
        cell.detailTextLabel.text = [_priceFormatter stringFromNumber:product.price];

......
}

我的错误是什么？谢谢..

你试过吗

SKProduct *product = (SKProduct *)[_products objectAtIndex:indexPath.row];
