SfPullToRefresh is not displayed in iOS project

[Passakorn]

Hi,

I installed SfPullToRefresh to my Xamarin Forms project. It works perfectly fine in Android but NOT in iOS. (Display blank instead of SfListView as its content)
I already added "SfPullToRefreshRenderer.Init();" in my AppDelegate (FinishedLaunching method with others like SfListView/SfTabView which also work fine in iOS)
I take a look in iOS project references and it has all required libraries (https://help.syncfusion.com/xamarin/sfpulltorefresh/getting-started#sfpulltorefresh-for-xamarinforms) due to my SfTabView is still working fine. I am using Xamarin Forms version 3.0.0.482510. and SfPullToRefresh version 16.2.0.41

Kindly request to investigate this issue , Thanks

Hi Passakorn, 

 

Thanks for contacting Syncfusion Support, 

 

We have checked your query. You have added SfPullToRefreshRenderer.Init() in AppDelegate class. Similarly If you use SfListView in your project it is necessary to add SfListViewRenderer.Init() in the AppDelegate class. If you have not added, the View in iOS will be blank. Please refer the below UG link for more details.

I already added both pieces of code. When I comment SfPullToRefresh tag in XAML, the SfListView is display normally.

Here is actual code

 

                                       ProgressBackgroundColor="#428BCA" 

                                       TransitionMode="Push" 

                                       IsRefreshing="False"

                                       VerticalOptions="FillAndExpand" 

                                       HorizontalOptions="FillAndExpand"

                                       PullingThreshold="100"

                                       RefreshContentHeight="50"

                                       RefreshContentThreshold="50"

                                       RefreshContentWidth="50">

           

               

                                       LoadMoreOption="Auto"

                                       LoadMoreCommand="{Binding LoadWorkListItemsCommand}"

                                       LoadMoreCommandParameter="{Binding Source={x:Reference Name=ListViewWorkItems}}"

                                       ItemsSource="{Binding WorkItems}" ItemSize="130" AutoFitMode="None" SelectionMode="None"

                                       SelectionBackgroundColor="Transparent"

                                       ItemTemplate="{StaticResource WorkListDataTemplateSelector}" 

                                       VerticalOptions="FillAndExpand" 

                                       HorizontalOptions="FillAndExpand">

Looking forward for the solution.

Thanks.

Here is what I found out, I put SfPullToRefresh in FlexLayout which is introduced in Xamarin 3.0. It is NOT displayed in iOS even set VerticalOption and HorizontalOption of FlexLayout to FillAndExpand but it is displayed normally in Android. Now I have changed FlexLayout and StackLayout and it is displayed normally for both of iOS and Android. So in this case, the issue is SfPullToRefresh (Forms) is not support FlexLayout in iOS. Cheers
