Xamarin iOS How to Zoom on UIView and UITableView

I am developping an iPad app using Xamaring that has several views in the storyboard (UIView and UITableView). My users want to zoom on usual pages (as they are used to in a web browser or so).

So, having read about UIScrollView, I simply tried to put my page views embedded within a UIScrollView, but I can neither scroll nor pinch-zoom: nothing happens.

As for the setup: in the StoryBoard, I add a UIScrollView to the UIViewController which fills the parent. I then add content to the UIScrollView, which I want to be zoomable (e.g. for people with poor sight).

So the question is quite simple: how can I get a view fitting within its original parent but that can be zoomed onto ?

Thanks in advance!

I have never done this myself, so I dont know if this is all it takes. But have you added the max- and min-scroll and all that? 

scrollView.MaximumZoomScale = 3f;
scrollView.MinimumZoomScale = .1f;
scrollView.ViewForZoomingInScrollView += (UIScrollView sv) => { return     imageView; };

(in your case i guess it needs to return the view);

If that doesent do the trick, take a look at "Scrolling and zooming a view hierarchy on this page: http://www.raywenderlich.com/10518/how-to-use-uiscrollview-to-scroll-and-zoom-content
