[Shraddha Patange]

hello, am using a popup layout in the android and iOS side 

In android, it is working fine

but in the iOS side app crashes while clicking on button click event

code - 

void PublicBtnClicked(object sender, EventArgs e)

        {

            VisibilityPopup.Show();

        }

 <sfPopup:SfPopupLayout x:Name="VisibilityPopup">

                            <sfPopup:SfPopupLayout.PopupView>

                                <sfPopup:PopupView x:Name="popupview" AutoSizeMode="Height" ShowFooter="False" HeaderTitle="Change Visibility">

                                    <sfPopup:PopupView.PopupStyle>

Hi Shraddha,

We have checked the reported issue with the code snippet. Unfortunately, we could not able to reproduce the issue in our end and it is working fine as expected in Xamarin forms iOS platform. We have attached the tested sample for your reference.

Sample link : https://www.syncfusion.com/downloads/support/directtrac/general/ze/Popup_Demo_2-758335303.zip

 

Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us back.

Regards,
Karthik Raja

thank you for this sample code

surprisingly, this code is working on the iOS side but the same code I incorporated in my project, and again its throwing error at main.cs file in the iOS project

I also share the snippet of the error.

Please have a look

Hi Shraddha,

Thanks for the update. We suspect that you have not initialized the renderer for SfPopuplayout. So only the issue occurs when showing the popup in your side. We request you to initialize the Renderer for the SfPopupLayout in iOS project. For more details, please refer to the below UG.

 Hi Shraddha,

It is possible to reproduce the issue in simple sample ?. If, not please share full call stack details to proceed further.
