I am using Portable xamarin cross platform. I have two project android and IOS.

I have to make form as transparent form. I have written code for same and this code perfectly working in android but not in IOS 

**Below is my code:**

```
  <ContentPage BackgroundColor="#00000000">

        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="180"></RowDefinition>
                <RowDefinition Height="*"></RowDefinition>
                <RowDefinition Height="200"></RowDefinition>
            </Grid.RowDefinitions>

            <StackLayout Grid.Row="0" VerticalOptions="StartAndExpand" HorizontalOptions="FillAndExpand" BackgroundColor="#80000000" HeightRequest="175" >

            </StackLayout>

            <BoxView HeightRequest="200" Grid.Row="1"></BoxView>

            <StackLayout VerticalOptions="End" HorizontalOptions="FillAndExpand"  BackgroundColor="#80000000" HeightRequest="160"  Grid.Row="2" >
                <Label Text="05:00" FontSize="60" FontAttributes="Bold" TextColor="White" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" ></Label>
            </StackLayout>
        </Grid>
