I was doing my test programming in objective-c and i was doing some UI work with interface builder, but whatever I did in the header file I added, interface uilder does not recognize it. unless i open everything in Xcode, and did the same thing, interface builder recognized it immediately.

Some info about this: http://cocoawithlove.com/2009/02/interprocess-communication-snooping.html

Is there anything I can do to get around that?

For now, simply drag your header file (with the @interface) onto IB, and IB will scan it for outlets. If you are using a xib, it stores the path to this interface file in the xib, and will rescan it in some situations (not entirely clear on how it works).
