Let's say I have a project which includes a nib N1 which builds a
target T1.
Now I want to add a new target T2 which builds a variant of of T1
that adds
some elements to nib N1 and removes some others (N2).
Given that you don't want to maintain two separate nibs, I would boil
down the overlap between N1 and N2 into a new nib, N0, that contains
only those elements that exist in both. Depending on the extent of the
non-overlapping pieces, they can either be created programmatically
after N0 is loaded depending on which target is running, or nibs N1
and N2 can contain the remaining pieces such that they can be loaded
in and spliced into N0 (adding new views to tab views, etc etc. If you
design the nib and interface properly to segregate the common and
target-specific functionality, this should be fairly straightforward.
Yes, I had thought about that possibility. If it is just a view or a
subview (an area in a view) this is probably easy to do. It gets more
complicated if there are other objects in the nib that need to be
connected. Not impossible to do though.
Also it moves the work needed to "do" the target specific
modification to run-time instead of build-time. Not that this would
usually be a huge amount of much work, but it is somewhat wasteful.
In addition to the work special code is also needed for this,
bloating the app with stuff that should not really be necessary.
