Xamarin 为 iOS 形成圆形图像

Question

I can only see the rounded images in Android, I tried it on iOS and they appear as squares.

            <StackLayout>
                         <RelativeLayout>
                            <Frame CornerRadius="60" 
                                  HeightRequest="{OnIdiom Phone=190,Tablet=355}"
                                  WidthRequest="{OnIdiom Phone=380,Tablet=710}"
                                  HorizontalOptions="Center"
                                  Padding="0"
                                  IsClippedToBounds="True"
                                  RelativeLayout.XConstraint="{OnIdiom Phone=15,Tablet=30}"
                                  RelativeLayout.YConstraint="{OnIdiom Phone=30,Tablet=30}">
                              <Image Source="kuwait3.jpg" 
                                     HorizontalOptions="Center"
                                     VerticalOptions="Center"
                                     RelativeLayout.HeightConstraint="{OnIdiom Phone=70,Tablet=310}"
                                     RelativeLayout.WidthConstraint="{OnIdiom Phone=70,Tablet=500}"/>
                            </Frame>
                        </RelativeLayout>
                    </StackLayout>

You should make your frame round and then your image will be round too:

<StackLayout>
    <RelativeLayout>
        <Frame CornerRadius="95" 
                              HeightRequest="{OnIdiom Phone=190,Tablet=355}"
                              WidthRequest="{OnIdiom Phone=190,Tablet=710}"
                              HorizontalOptions="Center"
                              Padding="0"
                              IsClippedToBounds="True"
                              RelativeLayout.XConstraint="{OnIdiom Phone=15,Tablet=30}"
                              RelativeLayout.YConstraint="{OnIdiom Phone=30,Tablet=30}">
            <Image Source="Images1" 
                                 HorizontalOptions="Center"
                                 VerticalOptions="Center"
                                 RelativeLayout.HeightConstraint="{OnIdiom Phone=70,Tablet=310}"
                                 RelativeLayout.WidthConstraint="{OnIdiom Phone=70,Tablet=500}"/>
        </Frame>
    </RelativeLayout>
</StackLayout>

The HeightRequest and WidthRequest should be same, and the CornerRadius should be half of HeightRequest/WidthRequest .
