core-plot

I downloaded the Core Plot example application, but when I compile it I saw a few errors. I then added the Core Plot SDK, but in this SDK there is no class named CPGraphHostingView. Therefore, I added the class manually from this link.

However, I now see the following error:

ERROR -  "_OBJC_CLASS_$_CPGraphHostingView", referenced from:

How can I work around this to get the sample application to compile?
