Adding a pull to refresh feature to UIWebView iOS

I'm looking to add a Pull to refresh feature to a UIWebView that I have in an app. I've used Pull to refresh in the past on table views, but I'm struggling to find any good tutorials/libraries to help me add it to UIWebViews specifically and this project.

I did get some of the way using PullToRefreshView by chpwn (https://github.com/chpwn/PullToRefreshView) but I can't get it detecting the drag. Does anyone know a better plug in/library?

I'm new to iOS development, so this may not be the best way… but it worked for me.

I took the controller that was wrapping my WebView and I changed it to a UITableViewController (it was just a UIViewController previously) so that I could take advantage of the refreshControl property of that controller (ios6 and up). I'm not making use of the TableView inside of the UITableViewController (though, it does seem to require one to exist, which I include, but I just don't populate it). I added 2 methods to the controller:

- (void)addPullToRefresh
{
    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
    refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:@"Pull to Refresh"];

    [refreshControl addTarget:self.myWebView action:@selector(reload)
      forControlEvents:UIControlEventValueChanged];
    self.refreshControl = refreshControl;
}

- (void)stopRefresh 
{
    [self.refreshControl endRefreshing];
}

I put a call to [self addPullToRefresh]; in viewDidLoad, and I added a call to [self stopRefresh]; in webViewDidFinishLoad:

I got my instructions for how to use the refreshControl property of UITableViewController here.
