我的应用程序在模拟器上运行，但不在设备上运行
我遇到这个错误的问题：
Undefined symbols for architecture i386:
当我构建并运行时，它在模拟器上成功运行，但在设备上运行失败，我尝试一个简单的新项目，我尝试在设备上运行它，没问题，但这个项目没有由于该错误而无法运行，完整的堆栈错误是这样的：

我更改了构建模式，因此我选择了设备（在我的情况下，我使用 iPod 4.3.5），现在我有另一个错误：
'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，请帮我找出导致这一切的问题可能是什么。
I have a problem with that error :
Undefined symbols for architecture i386:
When I build and go, it run successfully on the simulator but not on the device, I try a simple new project, I try to run it on the device, it was ok, but this project didn't run because of that error, the full stack error is this :

I changed the build mode, so I have choosed the device(in my case i use an iPod 4.3.5), now I have an other error :
'FavoriteCities.app' was built for 'i386', but the device 'iPod (Imac)' requires 'armv7' or compatible architecture.
FavoriteCities is my application name, please help me to figure out what could be the problem causing all that.

您需要更改设备构建的构建架构。 iOS 应用程序默认应该是armv6/7，但我猜你或你所做的事情搞乱了这些设置。
（在 Xcode 4 中）选择您的项目，转到“构建设置”选项卡并确保其如下所示：
You need to change build architecture for device builds. It should have been armv6/7 by default for iOS app, but I guess you or something you did messed those settings up.
(In Xcode 4) select your project, go to Build Settings tab and make sure it looks like this:
