使cocopods管理开源库编译出现Library not found for -lPods问题的解决方法

1. 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".
