Xamarin iOS image change transition -

i developing app xamarin.ios , not using xamarin.forms.
have screen have set image view.
change between 2/3/4 images transition (fade, move in ... not matter).
there way can that?
here code until now:

        imgview.animationimages = new uiimage[] {             uiimage.frombundle ("tmp_running.jpg")             , uiimage.frombundle ("tmp_cycling.jpg")          } ;         imgview.animationrepeatcount = 0;         imgview.animationduration = 3;         imgview.startanimating (); 

i have tried approach:

        catransition customtransition = new catransition();         customtransition.fadeinduration = 3.0f;         customtransition.fadeoutduration = 3.0f;         customtransition.timingfunction = camediatimingfunction.fromname(             camediatimingfunction.easeineaseout);         customtransition.type = catransition.transitionfade;          , :          imgview.layer.addanimation(customtransition, null); 

but nothing worked.

do know how simple task?

could this:

    static int count = 0;     uiimageview _imageview;      public override void viewdidload ()     {         base.viewdidload ();          _imageview = new uiimageview (new cgrect(0, 0, 100, 100));         _imageview.image = new uiimage ("1.png");         add (_imageview);          animateimage ();     }      public void animateimage()     {         var animationimages = new list<uiimage> () {             uiimage.fromfile ("1.png"),             uiimage.fromfile ("2.png"),             uiimage.fromfile ("3.png"),             uiimage.fromfile ("4.png"),             uiimage.fromfile ("5.png")};          uiimage image = animationimages[count % animationimages.count];          uiview.transition (_imageview, 3.0,             uiviewanimationoptions.transitioncrossdissolve,             () => {_imageview.image = image;},             () => { animateimage ();                     count++; }         );     }
