Fix UITableViewController offset due to UIRefreshControl in iOS 7

Question

I'm setting up a UIRefreshControl in my uitableviewcontroller, but there is a big gap between the navbar and the top of the uitableview. Playing with 'adjust scroll view insets' doesn't help, as the controller will underlay the navbar at startup. I could disable 'under top bars', but I want that ability when scrolling. When poking around in the debugger, I noticed at various times the tableView.contentInset is offset by 82 points, which is different from the ususal 20/64 pt offset people talk about regarding the new ios7 bar behavior. What's going on here?

Found a solution while poking around more; hope it saves someone a few hours!

I needed to instantiate my UIRefreshControl after viewDidLoad:, or avoid setting its attributedTitle in code at least until after that (e.g. if I enabled refreshing of the table in IB). Setting the string inside viewDidLoad: messes up iOS's layout of the control+tableview, but it's ok within viewWillAppear: or later once the geometry is set. And I think 82 points is the height of the UIRefreshControl. Setting the refresh title in IB would've also avoided this problem, except that I was doing so in code because I didn't want to have to enable refreshing in IB all the time with each of my tables.
