General remarks
As the metaioMobileSDK framework is a static C++ library, any files that import it have to be compiled as Obj-C++. This is done automatically by renaming the file to *.mm. Alternatively you can change the compilation settings of your XCode project to compile the entire source code as Obj-C++.
Use the latest iOS SDK (currently iOS 5) to build your applications.
