引入cocoaPods后。第一次编译,或者运行update后 可能报这个错误：

Pods was rejected as an implicit dependency for 'libPods.a' because its architectures 'x86_64' didn't contain all required architectures 'i386'

查了些资料，在网上有一种解决方法是去设置podproject的  valid Architectures 与你的项目project的 valid Architectures 一致

试了试没有成功，

经过尝试最后找了解决方式：详细的解决方式例如以下图：

确保3的地方设置为最新的sdk，确保4的地方设置和project设置一样

更新：再次遇到这个问题。依照上面方法无法解决。请尝试下面解决方法：

A friend updated Cocoapods in our project. When I pulled the latest stuff from git I got the following error:

Pods was rejected as an implicit dependency for 'libPods.a' because its architectures 'x86_64' didn't contain all required architectures 'i386'

This results in

ld: library not found for -lPods-___PODLIBRARY____
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have searched around for hours now trying to find it. The most common fixes I've tried are..

• Deleted derived data
• Delete build data
• Delete pods, and reinstalled with 'pod install'
• Clean project
• All of the above at the same time
• Experimented with 'Build Active Architecture Only', both in our project and in Pod Project. Inserted armv7 and armv7s as hard code instead of $ variable
• Experimented with 'Architectures', both in our project and in Pod Project. Inserted armv7 and armv7s as hard code instead of $ variable

We are aiming for iOS 8, iPhones.

My friend got it to work by combining the first 4 options, but I cannot.

Does anyone have any suggestions? We're supposed to release before christmas so production time is precious :D
