UICollectionView UIRefreshControl Doesn't Animate After Visiting a Different View

I have a UIRefreshControl connected to a UICollection that is defined this way for pull to refresh:

    self.refreshControl = [[UIRefreshControl alloc] init];
    [self.refreshControl addTarget:self action:@selector(startRefresh:)
    self.collectionView.alwaysBounceVertical = YES;
    [self.collectionView addSubview:self.refreshControl];

This works fine. However, whenever I move to a new view by either pushing a new view controller or displaying the sliding sidebar menu, and return to this view, the refresh control starts displaying the image for a control pulled all the way (i.e. it doesn't animate and shows the full circle). However, if I pull down fully and release, the refresh control returns to normal functionality. The control works fine, it just looks funky the first time you pull after navigating elsewhere.

I would love any feedback on what might be going wrong. Thanks!

This is what the image looks like when not working (note I am linking to an online image, this is not from my app so this doesn't show that the collectionview is being pulled down):

Posted solution below worked, but I had to do some extra work to figure out when my top view controller received focus from the sidebar menu that I was using (ECSlidingViewController): Is there a way for the Top View Controller in ECSlidingViewController to know when the sidebar menu has been dismissed?

I had a slightly different issue but the symptoms were similar. This is what worked for me:

- (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];

  _refreshControl.hidden = YES;
}

- (void)viewDidLayoutSubviews {
  [super viewDidLayoutSubviews];
  if (_refreshControl.isRefreshing) {
    [self.collectionView sendSubviewToBack:_refreshControl];
  }
}
