我的游戏如何在开始屏幕上显示宽图标？

Question

我正在为WP8创建一个游戏,但它在XNA中.如何让它具有开始屏幕的宽图标？默认情况下仅支持小和普通

由于XNA仅支持WP7应用,因此您必须检查您的应用是否在WP8上运行,如果是,请使用反射将磁贴更新为WP8图标.这个代码片段在这篇MSDN文章@Windows Phone OS 7.1应用程序中添加Windows Phone 8 Tile功能的例子就是一个很好的例子

您可能更容易使用Mangopollo库,该库具有与WP8类似的API内置的功能.这是包装WP8 API的源代码,可以从WP7 @ http://mangopollo.codeplex.com/SourceControl/changeset/view/100687#2023247调用

这里是在WP7应用程序中使用WP8宽磁贴的Mangopollo代码片段:

if (!Utils.CanUseLiveTiles)
{
    MessageBox.Show("This feature needs Windows Phone 8");
    return;
}

try
{
    var mytile = new FlipTileData
    {
        Title = "wide flip tile",
        BackTitle = "created by",
        BackContent = "Rudy Huyn",
        Count = 9,
        SmallBackgroundImage = new Uri("/Assets/logo159x159.png", UriKind.Relative),
        BackgroundImage = new Uri("/Assets/Background336x336_1.png", UriKind.Relative),
        BackBackgroundImage = new Uri("/Assets/Background336x336_2.png", UriKind.Relative),
        WideBackContent = "This is a very long long text to demonstrate the back content of a wide flip tile",
        WideBackgroundImage = new Uri("/Assets/Background691x336_1.png", UriKind.Relative),
        WideBackBackgroundImage = new Uri("/Assets/Background691x336_2.png", UriKind.Relative)
    };

#if ALTERNATIVE_SOLUTION
  var mytile = Mangopollo.Tiles.TilesCreator.CreateFlipTile("flip tile",
    "created by", "Rudy Huyn",
    "This is a very long long text to demonstrate the back content of a wide flip tile",
    9, new Uri("/Assets/logo159x159.png", UriKind.Relative),
    new Uri("/Assets/Background336x336_1.png", UriKind.Relative),
    new Uri("/Assets/Background336x336_2.png", UriKind.Relative),
    new Uri("/Assets/Background691x336_1.png", UriKind.Relative),
    new Uri("/Assets/Background691x336_2.png", UriKind.Relative));
#endif
    ShellTileExt.Create(new Uri("/MainPage.xaml?msg=from%20wipe%20flip%20tile",
      UriKind.Relative), mytile, true);
}
catch
{
    MessageBox.Show("remove tile before create it again");
}

还有一件事需要记住,即使XNA应用程序是WP7应用程序,其他WP8 API也可以直接从XNA使用.这是一个关于如何在WP7应用程序(包括XNA)上使用WP8 in-app purhcase的示例.这里有一个关于如何在WP7应用程序中使用新的WP8启动器和选择器的示例(向下滚动).
