我的应用程序在模拟器上运行，但不在设备上运行

Question

我遇到了这个错误的问题：

Undefined symbols for architecture i386:

当我构建并开始时，它在模拟器上成功运行但在设备上没有运行，我尝试了一个简单的新项目，我尝试在设备上运行它，没关系，但是这个项目没有运行因为那个错误，完整的堆栈错误是这样的：

我改变了构建模式，所以我选择了设备（在我的情况下我使用的是iPod 4.3.5），现在我还有一个错误：

'FavoriteCities.app' was built for 'i386', but the device 'iPod (Imac)' requires 'armv7' or compatible architecture.

FavoriteCities是我的应用程序名称，请帮我弄清楚导致这一切的问题是什么。

（在Xcode 4中）选择你的项目，转到Build Settings选项卡并确保它看起来像这样：
