iOS Use of undeclared identifier

[chrispr0ls]

Hi.

I'm trying to use g3m in an app I'm working on but when I #import layer related classes in my map view controller, the project won't build and finds errors such as:

"Use of undeclared identifier '_timeToCache'; did you mean 'getTimeToCache'?" in getTimeToCache() in RasterLayer.hpp
"Member initializer '_prevPos' does not name a non-static data member or base class" in TouchEvent.hpp.
Or "No member named '_errors' in 'RenderState'; did you mean 'error'?" in RenderState.hpp

I've already made an Hello World app that works and I just reused the same code in the other app.

Maybe it's a problem from the build settings, but I cross checked the configurations between my Hello World app and the other app and found no differences.

I hope you can understand my issue and someone already faced that problem. Thanks.
