How to develop distributable UI controls for iPhone?

Question

I would like to develop a reusable UI control for iPhone. How should I go about doing this? When I say reusable I mean it's packaged in a dll (or whatever is used on iPhone platform) so it can be reused on multiple projects.

Answer 1

While dynamic libraries are not allowed to be used in iPhone applications that are to be sold on the iPhone App Store, here's a tutorial on building static libraries with the iPhone SDK. (assuming you don't want to release source code)

Answer 2

You have two options:

1. Supply the full source code. Other developers can then add it directly to their app.
2. Distribute the compiled version of your code as a static library.

As you're planning to develop a UI control, I suggest you also develop an IB plugin and ship that with it too.

Answer 3

You probably want to provide custom Interface Builder objects, or maybe source code libraries.
