Question

I’m using Monotouch to develop an iPhone application.
I’m aware there are answers out there for this question already for Objective-C. For example:

Stop UIWebView from bouncing vertically

This answer is ideal. I figured I could just take it, and turn it into C# and it’ll be fine.

The Objective-C code is:

  for (id subview in webView.subviews)
    if ([[subview class] isSubclassOfClass: [UIScrollView class]])
      ((UIScrollView *)subview).bounces = NO;

I couldn’t find anything similar to isSubclassOfClass: in C# and after a little experimenting, I found my webView only contained one subview, which was a scrollview. So I tried the following C# code:

foreach (var view in webView.Subviews)
{
   webView.Subviews[0].Bounces = false;
}

This should’ve worked except the returned type of webView.Subviews[0] was type UIView not UIScrollView – this meant the compiler complains the UIView doesn’t have a property “bounces” (which is correct.)

So my question is, what would be the appropriate way of doing this? Is there a way I can get the UIScrollView instance from the subviews? Or am I going about this completely the wrong way?

Thanks.

Answer 1

Luke,

If you’re wanting to follow the same example as the Obj-C then you will want to do something like this;

foreach (var view in webView.Subviews.OfType<UIScrollView>())
{
   view.Bounces = false;
}

since the example above assumes that the first view in a webView is a UIScrollView, which may change in the future.

Hope this helps,
