Remove hightlight, when swipe ends. Or just catch event when swipe ends

[mister-giga]

What did you do?

I added custom gesture recognizer,. I did override the TouchesEnded method.

What did you expect to happen?

TouchesEnded to be fired after I finished swiping finger on the chart (with highlighting enabled)

What happened instead?

TouchesEnded was never called after swiping end, only if it was a tap. I suppose it shall happen after swiping as well, since there are no other methods to override for swipe ending.

After a funny journey on the github and stackoverflow I got answer to my question.
I found that BarLineChartViewBase adds NSUIPanGestureRecognizer, and after adding mine as well, made it not to draw the highlighter so I had to call the func of BarLineChartViewBase named panGestureRecognized but it was not public. And I am on Xamarin.iOS I had to do some reflection for objective C and c# and here is the code

        var list = Control.GestureRecognizers.ToList();
        var old = list.First(x => x is UIPanGestureRecognizer);
        list.Remove(old);
        var our = (new UIPanGestureRecognizer(uIPanGestureRecognizer =>
        {
            ObjCRuntime.Selector selector = new ObjCRuntime.Selector("panGestureRecognized:");
            var theStaticClassType = typeof(UIView).Assembly.GetType("ObjCRuntime.Messaging");
            MethodInfo staticMethodInfo = theStaticClassType.GetMethod("void_objc_msgSend_IntPtr");
            staticMethodInfo.Invoke(this, new object[] { Control.Handle, selector.Handle, uIPanGestureRecognizer.Handle });

            if (uIPanGestureRecognizer.State == UIGestureRecognizerState.Ended)
            {
                 //code that happens when swipe ends
            }
        }));
        list.Add(our);

        Control.GestureRecognizers = list.ToArray();

Where Control is LineChartView. I used this in custom renderer for Xamarin.Forms and it works fine
