I have an iOS project first made in Xcode 4.6. I have update it to Xcode 5.0.2. Now I want to change the project to using CocoaPods to manage the third party pods.
Due to a newer to CocoaPods. I search the Internet to how to install CocoaPods and so on. Now it's OK. So I run the pod install to get "AFFnetworking 2.1.0". .xcworkspace generate successfully. Then I open the workspace. I saw this in the navigation

There are many question mark. I think this means that Xcode 5.0.2 didn't know the AFNetworking 2.1.0 added by CocoaPods. And If I write the "#import "AFNetworking.h" in a .m file. Xcode will say that can't find the "AFNetworking.h".
I am a newer to CocoaPods. So home someone could help me. Thanks a lot.
