Class Diagram by omnigraffle
 

Omni Graffle Tool has the facility of importing Xcode Projects(.xcode)
It uses the objective C Headers to construct a diagram of the inheritence, protocol and category relationships
After opening the .xproj in omnigraffle it creates class diagram but it also includes OS provided classes (eg NSView,NSobject)

While importing the project if i don't include frameworks
It gives Diagram with no interconnection between them

How can i get complete Diagram without OS Classes(excluding framework) by directly importing my xcode project..

Wrong forum.
