I have a small C++ application which I imported Objective-C classes. It works as Objective-C++ files, .mm, but any C++ file that includes a header which may end up including some Objective-C header must be renamed to a .mm extension for the proper GCC drivers. Is there a way to write either a purely C++ wrapper for Objective-C classes ...

I am using code from this site: http://www.spacesimulator.net/tut4_3dsloader.html It works in their example project but when I placed the code into a class for easier and more modular use, the texture fails to appear on the object. I've double checked to make sure the texture ID is correct by debugging them side by side. On my project ...
In general, if you have a class that inherits from a Thread class, and you want instances of that class to automatically deallocate after they are finished running, is it okay to delete this?

If there is no function overloading, the function name serves as the address of the function code, and when a function is being called, its address is easy to find using its name. However with function overloading, how exactly can the program find the correct function address? Is there a hidden table similar to virtual tables that stores...
