使用OnPlatform->On标签的样式：

             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="...">
    <ContentPage.Padding>
        <OnPlatform x:TypeArguments="Thickness">
            <On Platform="iOS, Android" Value="10, 20, 20, 10" />
        </OnPlatform>
    </ContentPage.Padding>
    ...
