应用程序可以在 iPhone 上运行，但它不能在 iPod Touch 上运行

Question

我有一个可以在 iPhone 3GS 或 4 上部署的应用程序，它可以正常工作。但是当我尝试在 iPod Touch 第 3 代和第 4 代上部署它时，它构建时没有错误，但除了黑屏之外什么都没有出现。 这是我尝试安装应用程序时从设备获取的日志。

Answer 1

好的，我已经很容易地解决了这个问题。即使我已经在 pList 中声明了我的 nib 文件，当我查看项目目标摘要时，不知何故只有 iPad nib 文件显示为主界面。所以我把应该在那里的那个放在那里，现在它也在 iPod 上工作。

Answer 2

您似乎正在尝试获取手机类型信息（大概是 IMEI 等），而 iPod Touch 上不会有任何信息。

Answer 3

我会寻找 2 个可能的原因：iOS 版本、手机特定代码。

对于第一个选项，我会尝试在不同版本上使用 iphone 模拟器（您可以在模拟器本身上更改它）。如果这看起来不是问题，请尝试在您的代码中搜索一个您可能会使用手机特定功能的地方，例如尝试获取 IMEI。
