Are there any commercial add on programming controls for Mac and iOS Cocoa/Objective C?

Question

If developing for the Windows .NET APIs I can augment my efforts with 100's of commerically available add-on controls, graphing APIs and other usefull stuff. Can anyone point me in the direction of similar commerical software for Mac Cocoa/Objective C development?

Additionally:

Are there enough developers to do this commercially?

The point of my question was really is the Mac developer market mature enough to support commercial developer add-ons. I know there is "Open Source"... which everything seems to default to... mainly because no one has a led the way yet. Problem with open source freeware is one day were all turn into poor thin semi unskilled homeless people who plug free things together. We deserve better!

In case you hadn't noticed in the Mac market people are willing to pay for good stuff.

I have a history of selling development tools. You don't have to just give this stuff away.

Answer 1

Most such reusable source code and frameworks that I've seen are free, not commercial. Of those, most are under a BSD or MIT license, which means that you can use them in commercial closed-source software. (A very few come under one of the GPLs, which prohibit this.)

I have a list of these, although it is vastly incomplete now. I have a longer list in OmniOutliner, along with a grand plan for a better website for presenting it.

There's also MacCode, which is a repository of reusable source code and frameworks.

Answer 2

The Omni Frameworks are used in commercial software, though they themselves are open-source. I doubt there are enough OS X developers to really sustain a small independent closed-source library vendor. You may be able to publish open-source libraries and sell consulting or documentation services.
