Problem CorePlot in iPhone framework

I have followed the documentation of CorePlot. After doing everything, I am facing following problem:

error: 'CPLayerHostingView' undeclared (first use in this function)

 error: 'hostingView' undeclared (first use in this function)

What might be the problem ?

The name has changed: CPLayerHostingView is now CPTGraphHostingView. This change was effective in release 0.4 for iOS and MacOS for later releases.
