我的应用程序正在模拟器上运行，但不在设备上运行

Question

我对该错误有疑问：

Undefined symbols for architecture i386:

在构建和运行时，它在模拟器上成功运行，但在设备上无法运行，我尝试了一个简单的新项目，尝试在设备上运行，没关系，但是由于该错误，该项目未能运行，完整的堆栈错误是这样的：

我更改了构建模式，所以我选择了设备（在我的情况下，我使用的是iPod 4.3.5），现在出现另一个错误：

'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，请帮助我找出导致所有问题的原因。

您需要更改设备构建的构建体系结构。 对于iOS应用程序，默认情况下应该为armv6 / 7，但我想您或您所做的事情弄乱了这些设置。

（在Xcode 4中）选择您的项目，转到“构建设置”选项卡，并确保它看起来像这样：
