Pull To Refresh on UIScrollView

edited July 2015 in Xamarin.iOS

I have a UIScrollView within a UIViewController within a UITabBarController

I want to be able to let the user refresh the data in the UIScrollView (ideally by pulling on the control).

I have looked at using a UIRefreshControl, but note that these can only be used within UITableViewControllers.

What are my options ?

    var scroll = new UIScrollView(new CGRect(0, 64, this.View.Frame.Width, this.View.Frame.Height));
            scroll.UserInteractionEnabled = true;
            scroll.ShowsHorizontalScrollIndicator = false;
            scroll.ShowsVerticalScrollIndicator = false;
            scroll.BackgroundColor = UIColor.White;
            scroll.ContentSize = new CGSize(this.View.Frame.Width, 1000);
            var refresh = new UIRefreshControl();

    @ArturMalendowicz many thanks for this, I can see refresh user feedback from your code.

    It does not yet work with my code I need to dig a little deeper to find out why. One difference is that my scrollview has multiple UIViews in/on it and each of those contains a UITextview - so perhaps I should not expect to see the refresh wheel. Will investigate and find out what the problem is. Thanks again.

    Have you set UserInteractionEnabled to true and are you sure ContenSize is greater than screen size?

    Yes to the first, and for the second, the content size is wider than the screen width (10x), but not taller. I need to scroll panes left and right and don't want them to move vertically during normal scrolling.
