TabbedPage translucent tab bar on iOS

  • Artikkeli

This iOS platform-specific is used to set the translucency mode of the tab bar on a TabbedPage. It's consumed in XAML by setting the TabbedPage.TranslucencyMode bindable property to a TranslucencyMode enumeration value:

<TabbedPage ...
            xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
            ios:TabbedPage.TranslucencyMode="Opaque">
    ...
</TabbedPage>

Alternatively, it can be consumed from C# using the fluent API:

using Xamarin.Forms.PlatformConfiguration;
using Xamarin.Forms.PlatformConfiguration.iOSSpecific;
...

On<iOS>().SetTranslucencyMode(TranslucencyMode.Opaque);

The TabbedPage.On<iOS> method specifies that this platform-specific will only run on iOS. The TabbedPage.SetTranslucencyMode method, in the Xamarin.Forms.PlatformConfiguration.iOSSpecific namespace, is used to set the translucency mode of the tab bar on a TabbedPage by specifying one of the following TranslucencyMode enumeration values:

  • Default, which sets the tab bar to its default translucency mode. This is the default value of the TabbedPage.TranslucencyMode property.
  • Translucent, which sets the tab bar to be translucent.
  • Opaque, which sets the tab bar to be opaque.

In addition, the GetTranslucencyMode method can be used to retrieve the current value of the TranslucencyMode enumeration that's applied to the TabbedPage.

The result is that the translucency mode of the tab bar on a TabbedPage can be set:
