【中文标题】尝试所有这些步骤后，“应用内购买”仍然无法正常工作【英文标题】："In App Purchasing" still wont work after trying all these steps 【发布时间】：2013-08-15 19:31:36 【问题描述】：我已经执行了这几个步骤，以便在我的应用程序中使用五个非消耗性应用程序购买，但是当我转到将 IAP 代码链接到的 TableViewController 时仍然没有显示任何内容...（我也想非常感谢我遵循的教程，raywenderlich 让我走到了这一步）
-创建了一个新的应用ID -已成功完成链接和下载证书的所有步骤 将我项目的 xcode 上的捆绑 ID 更改为我为 我在 ios 开发者门户上的应用 -链接所有设备并创建一个测试用户帐户 -使iTunes上的非消耗性IAP连接并使用IAP编码中的标识符 -从我的 iTunes 帐户中注销我的手机，以便它可以与测试帐户一起使用 -IAP 的编码看起来是正确的，导入了商店套件并在 .m 文件中实现了产品标识符 -等待 24 小时让新创建的 IAP 与 iTunes Connect 同步 -我没有上传二进制文件！ 我打开了苹果主机，但没有上传任何东西 - 可以 这是问题所在？ 我删除了手机上的应用程序并重新安装以进行测试，但仍然 什么都没有当我成功运行构建时，我得到的只是一个页面，它看起来像是在加载一些东西，但没有一个空白页面，我可以下拉刷新，但仍然没有我创建的 IAP。
关于我还能做什么或添加什么的任何建议，如果您需要我上传所有我能做的文件的所有代码...

总结一下……
使用 StoreKit 访问应用内购买 API 并检索 运行构建时什么都不显示的列表 为我的应用指定产品标识符 显示产品，这似乎是一个问题，虽然它确实 显示一个屏幕，就像它即将加载一些东西然后什么都没有 页面上拉刷新【问题讨论】：
您通过调试了解到发生了什么？您的表格视图没有加载任何内容 - 好吧，这是为什么呢？它等待加载什么响应，得到什么响应？ 删除并重新安装应用程序，您可能仍然拥有旧捆绑包。 requestProductsWithCompletionHandler:^(BOOL success, NSArray *products) 返回一个空数组吗？ 同名 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath]; @"Cell" 这绝对是荒谬的代码量，期望其他人阅读和调试。请将其减少到证明问题所需的最低限度。 【参考方案1】：对于以后发现此帖子的任何人来说，在请求 IAP 时没有显示任何项目的原因是由于未为托管内容上传内容。
