Create class diagram from already existent iphone code

Question

does anybody know, how i could create automatically a UML class diagram from an already existent iphone project. Is it possible?

Thanks in advance.

Solution 1

Yes, you can use Doxygen:

1. Install Doxygen (with MacPorts: sudo port install doxygen).

2. Get a script like this and change the first lines to match your configuration.

3. Download these files and edit the Doxygen file so it says HAVE_DOT=YES and UML_LOOK=YES.

It will then generate and install a docset that you can read from the documentation browser, or just right click and show contents from Finder.

Or, if you want a graph of dependencies check: https://github.com/nst/objc_dep It uses graphviz.

Solution 2

See also OmniGraffle of all things. If you open an Xcode project with it, it will generate a full class diagram. It can be fairly overwhelming for a large project.

Crashes every time on larger projects, regardless of trial or paid.

My experience with OmniGraffle is the same as Oh Danny Boy's.

Same here. I could get it working only when I created dummy project and imported only files I need there. Crashes very often. Also the diagram it generates is absolute garbage. Does not show @property in diagram. Bad bad tool.

This happened for me when i tried to have it also import "frameworks", but unchecking that, it stopped crashing

The links in this post are dead. Are there updated links?

I fixed the links, Idk if that method still works, it’s 11 years old and intended for Objective-C projects. These days I make diagrams manually with OmniGraffle, tho the technology pieces to automate this process are already floating around.
