Just starting I'll say I'm new at this, but anyways.
I have my app set up where if you tap on a row of the tableview it takes you to a map of the location you picked. When I comment out my code for my UIRefreshControl everything works the way I want it to, but when I but I bring it back I can't click on the top two rows of the tableview.
Please find below the code that I'm commenting out.
refresher = UIRefreshControl()
refresher.attributedTitle = NSAttributedString(string: "Pull to See Closest Locations")
refresher.addTarget(self, action: "refresh", forControlEvents: UIControlEvents.ValueChanged)
self.tableView.addSubview(refresher)

I also wrestled with this issue, but it turned out to be really simple, luckily. Send the UIRefreshControl to the back in ViewDidLoad, and you're done!
Swift:
tableView.sendSubviewToBack(refresh)
Objective-C:
[tableView sendSubviewToBack:refresh];
