Issue in indicatorView

Question

Hello.

I'm implementing CarouselView in my Xamarin.forms app.

I'd like to insert Indicator View. I followed instructions and official sample but I get issue for iOS.

<CarouselView ItemsSource="{Binding ImageSourcesURL}"  
                                          Loop="False"  
                                              IndicatorView="indic"  
                                          >  
                                    <CarouselView.ItemTemplate>  
                                        <DataTemplate>  
                                            <StackLayout>  
  
                                                <Image Source="{Binding .}"  
                                                     
                                                    Aspect="AspectFill"  
                                                    HeightRequest="400"  
                                                    WidthRequest="400"  
                                                    HorizontalOptions="Center"/>  
  
                                            </StackLayout>  
                                        </DataTemplate>  
                                    </CarouselView.ItemTemplate>  
                                </CarouselView>  
  
                                <IndicatorView x:Name="indic"  
                                                 
                                       IndicatorColor="LightGray"  
                                       SelectedIndicatorColor="DarkGray"  
                                       HorizontalOptions="Center" />  

Very simple code. Android works, iOS doesn't.

I attached image of error

Any idea?

Hello,

Welcome to Microsoft Q&A!

I test your code and official sample, it both works fine without error .

allowsContinuousInteraction is only available from iOS 14, so I check the source code of IndicatorViewRenderer ,

   if (Forms.IsiOS14OrNewer)  
   {  
   	UIPager.AllowsContinuousInteraction = false;  
   	UIPager.BackgroundStyle = UIPageControlBackgroundStyle.Minimal;  
   }  

Everything seems to be working , would you mind sharing us a basic, reproducible project(you can upload to github and attach the link here) ?

Best Regards,
Cole Xia
