I use to provide dependencies for my objects from the outside. The Builder interface is a tool that helps to do this, but I cannot get it to work with multiple tips. As soon as I break the main tip into more files, I can no longer establish connections between objects in different tips. Using File Owner doesn't help much, as it only allows me to pass one object to the tip.
Example:

A B - , C D - . ( ), . A B, C D. (, C D, , A B C D .)
Interface Builder? ?
