c# - How to assign the UIPopoverPresentationControllerDelegate -

i try use uipopoverpresentationcontroller. presenting need assign delegate (uipopoverpresentationcontrollerdelegate) able use methods prepareforpopoverpresentation, popoverpresentationcontrollerdiddismisspopover , on.

if assign view controller delegate property get

error cs0266 cannot implicitly convert type 'uikit.uiviewcontroller' 'uikit.iuipopoverpresentationcontrollerdelegate'. explicit conversion exists (are missing cast?)

so options here? in native world 1 add required protocoll, can't in xamarin. want view controller presented in popover gets notification (prepare, did dismiss, ...). how can that?

of course create new instance of uipopoverpresentationcontrollerdelegate , assign it, have connect delegate view controller somehow (e.g. through events). there simpler solution?

edit

it looks xamarin has not exposed weakdelegate property , has made delegate class abstract class protocol , not interface. in scenario - have create class implements uipopoverpresentationcontrollerdelegate , uipopovercontrollerdelegate.

in future, it's worth noting there weakdelegate property (along delegate) allows assigning class delegate , implementing protocol implicitly through exportattribute on protocol methods. xamarin uses protocol's matching interface (such iuipopoverpresentationcontrollerdelegate) instead of matching abstract class (the uipopoverpresentationcontrollerdelegate class).

mostly incorrect original answer

it should possible uiviewcontroller class implement iuipopovercontrollerdelegate , implement methods need. ios protocols converted interface xamarin.ios , can find appending "i" protocol name.

public class testvc : uiviewcontroller, iuipopovercontrollerdelegate {     public override uipopoverpresentationcontroller popoverpresentationcontroller {         {             return base.popoverpresentationcontroller;         }     }      [export ("popovercontrollerdiddismisspopover:")]     public void diddismiss (uipopovercontroller popovercontroller)     {         throw new notimplementedexception ();     } } 

here example i've implemented few of popover methods. hope helps. haven't explicitly tested this, think should work. let me know if doesn't.
