找不到架构i386错误iOS的符号

Question

There are no errors in my code itself but when i try to run, I get this error - Symbol(s) not found for architecture i386 error iOS. I looked for answers but nothing so far has helped me. I am sure I am linking to the correct libraries.

Furthermore, The code does work when it's run in a different project by itself. Essentially, I made the pieces of an app and have run into this problem when getting them to all work together. Everything is identical between the two apps. The only real difference is that I am running it along with a coreplot code so i'm not sure if that has anything to do with it?

The error is occurring because of a TFHipple element. Here is a copy of the error :

I'm pretty sure I have all the frameworks I need

Answer 1

Check your build settings. If everything is correct, try a clean build of the whole project. Xcode is trying to link a simulator build of your app with an iOS device build of Core Plot.
