I have this ListView:

<ListView

    CachingStrategy="RecycleElement"

    x:Name="ItemList"

    HasUnevenRows="True"

    BackgroundColor="Transparent"

    SeparatorColor="{x:Static local:LmcColor.defaultFg}"

    HorizontalOptions="FillAndExpand"

    VerticalOptions="FillAndExpand"

    IsVisible="False"

    ItemSelected="ItemList_ItemSelected"/>

Its ItemTemplate is initialized as follows:

ItemList.ItemTemplate = new DataTemplate(() =>

    new ViewCell() { View = new ItemReadView() });

And ItemReadView is a ContentView containing a StackView containing an Image called ItemImage. I define a gesture recognizer for this Image:

TapGestureRecognizer handler = new TapGestureRecognizer();

handler.Tapped += ((object sender, EventArgs e) =>

{

    // Do stuff!

});

ItemImage.GestureRecognizers.Clear();

ItemImage.GestureRecognizers.Add(handler);

It worked fine in Xamarin Forms 2.5.1.444934. Now, in 3.3.0.967583, the "Do stuff" is being invoked for multiple image views after a single tap. I am not sure if the issue was present in Forms 3.1.0.637273. The bug only affects iOS.

As a workaround, I added a 200-msec delay before "doing stuff", and "stuff" is not "done" if a new event arrives in that interval. Luckily, the "real" event comes in last. Unluckily, the more I scroll the list view before tapping, the more events come in, and I'm afraid of some sort of resource overflow.

Has anyone noticed this? Are there any "proper" fixes? Is there anything I may be doing wrong? Should I replace TapGestureRecognizer with something else, and if so, with what?

Thanks!
