cocoa touch - UIRefreshControl incorrect title offset during first run and sometimes title missing

Question

The text is offset wrong by the first launch of UIRefreshControl... later sometimes the refresh text doesn't show up at all and just the spiny is visible

I don't think i had this issue with iOS6... might be related to iOS7

Is in a UITableViewController added as a child to a VC, which resides in a modal presented UINavigationController

- (void)viewDidLoad {

    [super viewDidLoad];

    [self setRefreshControlText:@"Getting registration data"];
    [self.refreshControl beginRefreshing];
}

- (void)setRefreshControlText:(NSString *)text {

    UIFont * font = [UIFont fontWithName:@"Helvetica-Light" size:10.0];
    NSDictionary *attributes = @{NSFontAttributeName:font, NSForegroundColorAttributeName : [UIColor blackColor]};
    self.refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:text attributes:attributes];

}

This is definitely an iOS 7 bug, but I haven't figured out exactly what caused it. It appears to have something to do with the view hierarchy — adding my UITableViewController as a child view to a wrapper view controller appeared to fix it for me at first, although the bug is back since iOS 7 GM.

It looks like adding the following code to your UITableViewController after creating the refresh view fixes the positioning issue for good:

dispatch_async(dispatch_get_main_queue(), ^{
    [self.refreshControl beginRefreshing];
    [self.refreshControl endRefreshing];
});
