Linker errors with ParseUI iOS and CocoaPods

问题

I was attempting to build an app using Parse and wanted to give ParseUI a shot. I imported Parse's main SDK using Cocoa pods, and it worked fine. When I decided to add ParseUI, I ran into problems.

Undefined symbols for architecture i386:

I've attempted things like forcing the inclusion of the Parse.framework for the linking of ParseUI, but it didnt seem to help. I'm not an expert with cocoapods or with XCode, so I don't know if there's something obvious I'm missing.

I've tried cocoapods 0.35 and 0.36-beta-1. This is a swift project, so I don't know if that could be causing some of the problems.

回答1:

You need to use the framework Bolts.frameworks. This framework is part of the Parse SDK. Another thing is that with the last version of Parse SDK (v1.6.2 right now) you'll have to import Parse/Parse.h, ParseUI/ParseUI.h or both, depending on which objects you are using. Tell me if you need more information about installing de Bolts framework! :)
