在Xcode iOS项目中使用C ++静态库（CCFits）

Question

I am trying to using the CCfits library in an iOS project. CCfits is a C++ wrapper to the c library cfitsio. I have the source code to both of these, and also have them built as static libraries (.a files). I would like to add the CCfits library (libCCfits.a) to an iOS project but when I am confused on how to access the library classes from my iPhone source files. I have the library added under "Link Binary with Libraries". I understand that Xcode needs me to import a header file, but what is the proper way to attach the headers to the project? Do I need to make a framework file somehow? Or is the .a file enough?

You can easily mix C++ and Objective-C using Objective-C++. In XCode just rename your .m files to .mm and it will recognize the files as Objective-C++. Then you can use the C++ classes in your Objective-C code ( some restrictions apply , but not many).

Since Objective-C is an extension to C you can use C libraries in any Objective-C program easily.
