Having the same problem and found a workaround that seems to fix it. This seems to be happening because the UIScrollView is slowing down the tracking of the pan gesture when you pull past the edge of the scrollview. However, UIScrollView is not accounting for changes to contentInset during tracking. UIRefreshControl changes contentInset when it … Read more
Try this: self.collectionView.alwaysBounceVertical = YES; Complete code for a UIRefreshControl UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; refreshControl.tintColor = [UIColor grayColor]; [refreshControl addTarget:self action:@selector(refershControlAction) forControlEvents:UIControlEventValueChanged]; [self.collectionView addSubview:refreshControl]; self.collectionView.alwaysBounceVertical = YES;
I believe there won’t be any simple solution to this problem. May be someone could write a separate library to implement this behaviour plus it will cause more complications once you cache data in tableview. But let us break down the problem and that might help you in achieving what you want. I have used … Read more

Pull to refresh is built in iOS. You could do this in swift like let refreshControl = UIRefreshControl() override func viewDidLoad() { super.viewDidLoad() refreshControl.attributedTitle = NSAttributedString(string: “Pull to refresh”) refreshControl.addTarget(self, action: #selector(self.refresh(_:)), for: .valueChanged) tableView.addSubview(refreshControl) // not required when using UITableViewController } @objc func refresh(_ sender: AnyObject) { // Code to refresh table view } … Read more
On a hunch, and based on DrummerB’s inspiration, I tried simply adding a UIRefreshControl instance as a subview to my UITableView. And it magically just works! UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged]; [self.myTableView addSubview:refreshControl]; This adds a UIRefreshControl above your table view and works as expected without having to use a … Read more
