是我姿势不对嘛？ https://github.com/Kapeli/Dash-iOS 按照 readme 编译，连接报错：

很明显是 Cocoapods 的问题，因为找不到的这些东西全是 pod 里包含的库，于是按照 pod 官方的 troubleshooting 尝试了：
If Xcode complains when linking, e.g. Library not found for -lPods, it doesn't detect the implicit dependencies:
Go to Product > Edit Scheme Click on Build Add the Pods static library, and make sure it's at the top of the list Clean and build again If that doesn't work, verify that the source for the spec you are trying to include has been pulled from GitHub. Do this by looking in <project dir="">/Pods/<name of="" spec="" you="" are="" trying="" to="" include="">. If it is empty (it should not be), verify that the ~/.cocoapods/master/<spec>/<spec>.podspec has the correct git hub url in it. If still doesn't work, check your Xcode build locations settings. Go to Preferences -> Locations -> Derived Data -> Advanced and set build location to "Relative to Workspace".
依然不行，继续尝试了： pod install pod update
依然不行，谷歌无果，求指点方向
