objective c - What's the difference between a Cocoa framework and a C static library? -

-

can explain me fundamental differences between cocoa framework , c static library?

in particular, i'm finding out in both cases have reference file (.framework or .a) in "link binary libraries" part target in xcode.

however, don't seem have put .a in "copy files". have put .framework "copy files". reason difference?

a static library compiled part of app, whereas framework distributed app (or system frameworks present) , linked dynamically. see this question.
