It looks like there are a number of other things wrong with this code. For example, the "initialize the SDK" line appears outside of any method declaration.
Is this file the ".h" file or the ".m" file? You won't be able to paste in methods into the ".h" file, those have to go in the ".m" file.
I'd suggest downloading our sample iPhone app project here, https://github.com/geoloqi/Geoloqi-iPhone-SDK, and trying to copy and paste code from it into your project matching things up when possible.
