(1) I don't think that's an example of modifying an *outlet*, though. What you
did was to modify the value of an ivar. The outlet is the name "loadedCell"
embedded in the nib; you didn't do anything about that (i.e. you didn't
magically change the *name*). You just *used* the outlet, in a perfectly normal
way: you loaded the nib with self as the owner and KVC was used to cause a
certain newly created instance (the cell) to be passed to setLoadedCell:.
(2) On iOS 4 it's better in this repeated loading situation to use UINib
instead of NSBundle to load the nib:
UINib* theCellNib = [UINib nibWithNibName:@"ComplexTableViewCell" bundle:nil];
[theCellNib instantiateWithOwner:self options:nil];
