Xamarin.Forms Slider iOS gesture failure

问题

When I try to use the Slider on iOS it slides out the Master menu. It works fine on Android.

One option would be to disable gestures all together but I haven't found a way to disable them for only that page. I would very much like to keep the sliding gestures for the other pages without sliders.

It sounds like your slider may be too close to edge of the page. If your design allows it, try adding a margin to the left and right of the slider.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:SliderTest"
             x:Class="SliderTest.MainPage">
   <StackLayout Orientation="Vertical" VerticalOptions="Center">
     <Slider Margin="10,0,10,0"/>
   </StackLayout>
</ContentPage>

And in case you need separate margins for iOS and Android, you can do that like this:

  <StackLayout Orientation="Vertical" VerticalOptions="Center">
    <Slider>
      <Slider.Margin>
        <OnPlatform x:TypeArguments="Thickness" iOS="10,0,10,0" Android="20,0,20,0"/>
      </Slider.Margin>
    </Slider>
  </StackLayout>
