UIRefreshControl will dismiss on all phones except iPhone 6+

Question

I'm using an instance of UIRefreshControl to reload the data in a UITableView.

If I run the app on any phone except the iPhone 6+, the refresh-control will disappear after the data refresh has finished.

However, if I run the app, on the iPhone 6+, the refresh-control will stay visible after the user has pulled down on the table-view to refresh the data. Below is a screenshot of the refresh-control visible behind elements of the table-view:

This behavior does not occur on any other phone except for the 6+. Below is the code for refreshing the table-view data, which is inside of viewWillAppear:

    if (self.refreshControl == nil) {
        UIRefreshControl *refreshControl = [UIRefreshControl new];
        refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:@" "];
        refreshControl.tintColor = [UIColor refreshColor];
        [refreshControl addTarget:self action:@selector(refreshTableView:) forControlEvents:UIControlEventValueChanged];

        self.refreshControl = refreshControl;

        self.tableView.backgroundView.layer.zPosition -= 1;
    }

Does anyone know why the refresh control will stay visible when refreshing a table-view on the 6+?

Answer 1

According to the accepted answer on this post, you have to manually remove and disconnect the refresh control.

That feels hack, and indeed, several[1] places[2] on the internet[3] seem to suggest calling endRefreshing inside of viewDidLoad. Some variations call for removing the refresh control and others say to endRefreshing instead.

Since I'm unsure which works, and because it probably depends on what your view controller looks like, I'll leave that up to you.
