UIRefreshControl's aren't meant to be subviews, they're meant to (literally) be the table's refresh control. UITableViewController has an outlet specifically for them (again, literally called refreshControl) that you should be using. As a subview of the table, you may be causing the table to assume it's a cell, rather than just a subview, which forces a recalculation around it. There will be cases where you do get lucky and the control may set itself in the right place, but this is, again, the result of undefined behavior.

UITableViewController is not meant to be a limiting class, and it certainly should not keep you from implementing "multiple table views" (which sound context-specific enough that they'd warrant a new view controller presented anyhow). If you are worried about having to write boilerplate for each class, write an abstract superclass controller for every table view you want to implement, and subclass it as necessary.
