[yuv4ik]

Description

Having a Label with multiple Spans with TapGestureRecognizers are not working on iOS.

Steps to Reproduce

1. Add the next Label to MainPage.xaml:

<Label
    FontSize="Micro"
    VerticalTextAlignment="Center"
    HorizontalTextAlignment="Center">
    <Label.FormattedText>
        <FormattedString>
            <Span Text="Long text about how we respect your privacy but you should actually check " />
            <Span Text=" Twitter " TextColor="Purple">
                <Span.GestureRecognizers>
                    <TapGestureRecognizer Tapped="OpenPP" />
                </Span.GestureRecognizers>
            </Span>
            <Span Text="and" />
            <Span Text=" Google" TextColor="Purple">
                <Span.GestureRecognizers>
                    <TapGestureRecognizer Tapped="OpenToc" />
                </Span.GestureRecognizers>
            </Span>
            <Span Text="." />
        </FormattedString>
    </Label.FormattedText>
</Label>

1. Add EventHandlers for both OpenToc and OpenPP.

Works fine with latest master code

[yuv4ik]

Glad to hear. I guess it is fixed just not released yet.

I tested with 3.5.0-pre3, and it works! You can update to that package now. Thank you!

But if you rotate the device and then tap on it, it just didnt work.

did anybody resolved this issue? I am facing the same issue. My app needs to work on iPad in landscape mode.

[charlesroddie]

The fix was merged but I think it just missed the 4.4.0 release. Hopefully the next release or prerelease.

Funny thing, it's not yet working in 2020 :D

Tried and Command and Tapped, no luck.

Xamarin.Forms 4.6.0.379-pre1

Any news about this issue?

The gesture is fired when the text in the span is in one line. but if the text is multi-line then the event is not fired.

Works only on label element but Not Working on span element. after updating visual studio for windows and mac to the latest version.

Encountered this issue just now. Setting the VerticalOptions to Center doesn't allow the second line to be selected. Haven't tested other LayoutOptions. This has something to do with the height request update of the span I think.

Solutions: You can either set the _HeighRequest_ of the Label with Span and clicking the second line tap gesture will work or just leave the _VerticalOptions_ to default and it will also work.

Experiencing the same problem. Nothing I do will make the gesture recognizer fire.

@samhouts Can you reopen this pls, it still doesn't work on iOS.
My specific use case is the label with spans is in a cell in a listview.

I've tested the original repo with 4.6.0.847, and I can tap the spans, even after rotating my device.

This leads me to believe that there is a different issue here. Can you please create a new issue and attach a small reproduction project that demonstrates the problem? Thanks!

I'm having an issue with multi tap gesture recognizers on a grid on iOS 13.5

I have a recognizer for 1 tap, and a second recognizer for 2 taps, both on the same grid.

Only gesture recognizer with 1 tap fires on iOS while both gesture for 1 tap, and 2 taps fire on Android.

(Editted)
Expected behavior is as on Android.
When tapped once, handler for 1 tap should fire and when tapped twice the handler for 2 taps should fire.

Tested on XF 4.6 and 4.7 on Visual studio Mac 8.6.5(build 23) and Microsoft Visual Studio 2019 Ver. 16.6.3
