What are M files and how to open them
Are you having problems opening a M file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.
What is a M file?
M files have multiple uses, and Objective-C Methods is one of them. Read more about the other uses further down the page.
Objective-C Methods File
These files are source code files that contain class implementations written in the Objective-C programming language, usually using Apple Xcode on a Macintosh computer.
In C++, programmers use .cpp and .h files, where a .h header file contains the definition of a class of private and public methods and variables, and the .cpp file contains the actual implementation.
Objective-C takes it a step further, and separates .h files into .h and .m files. The .h header file contains all public methods of a class, and the .m file contains all private methods and data only accessible by the class implementation itself.
