WindowsPhone 7.8 Tiles 1 : WideTile
7.8 SDK 终于出了（下载：http://www.cnblogs.com/sun8134/archive/2013/01/23/2872562.html）
可惜一个api都木有…
唯一增加的就是tile的变化
详细见MSDN文档：http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj720574(v=vs.105).aspx
A Windows Phone OS 7.1 app that runs on Windows Phone 8 or Windows Phone 7.8 supports the following Tile features:
For the default Tile, the flip Tile is the only supported template. For more information about this template, see Flip Tile template for Windows Phone 8.
For secondary Tiles, all Tile templates are supported: Flip Tile template for Windows Phone 8, Iconic Tile template for Windows Phone 8, and Cycle Tile template for Windows Phone 8.
Independently update the small and medium Tile sizes. You can also optionally support the wide Tile size.
You can use both push notifications and the ShellTile APIs to update Tiles.
默认的Tile只支持Flip Tile 我们来看看实现的效果吧：
首先要看下Flip Tile的结构，还是看MSDN文档吧：http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj206971(v=vs.105).aspx
下面准备需要的图片，大小分别为159*159，336*336，691*336
还有一张对应wp7.5的173*173
然后开始code，第一步摇先判断版本，是否为7.8
//设定版本
private static Version TargetedVersion = new Version(7, 10, 8858);
//判断是否满足版本要求
public static bool isTargetedVersion { get { return Environment.OSVersion.Version >= TargetedVersion; } }
如果大约等于7.8，则替换默认tile为Flip Tile：
ShellTile appTile = ShellTile.ActiveTiles.First();
// Get the new FlipTileData type.
Type flipTileDataType = Type.GetType("Microsoft.Phone.Shell.FlipTileData, Microsoft.Phone");
// Get the ShellTile type so we can call the new version of "Update" that takes the new Tile templates.
Type shellTileType = Type.GetType("Microsoft.Phone.Shell.ShellTile, Microsoft.Phone");
// Loop through any existing Tiles that are pinned to Start.
//var tileToUpdate = ShellTile.ActiveTiles.First();
// Get the constructor for the new FlipTileData class and assign it to our variable to hold the Tile properties.
var UpdateTileData = flipTileDataType.GetConstructor(new Type[] { }).Invoke(null);
// Set the properties.
SetProperty(UpdateTileData, "Title", "Main Tile Title");
SetProperty(UpdateTileData, "Count", 0);
SetProperty(UpdateTileData, "BackTitle", "Back Tile Title");
SetProperty(UpdateTileData, "BackContent", "Content For back tile.");
SetProperty(UpdateTileData, "SmallBackgroundImage", new Uri("Windows 8 59.png", UriKind.Relative));
SetProperty(UpdateTileData, "BackgroundImage", new Uri("Windows 8 336.png", UriKind.Relative));
SetProperty(UpdateTileData, "BackBackgroundImage", new Uri("", UriKind.Relative));
SetProperty(UpdateTileData, "WideBackgroundImage", new Uri("Windows 8 691.png", UriKind.Relative));
SetProperty(UpdateTileData, "WideBackBackgroundImage", new Uri("", UriKind.Relative));
SetProperty(UpdateTileData, "WideBackContent", "Content for Wide Back Tile. Lots more text here.");
// Invoke the new version of ShellTile.Update.
shellTileType.GetMethod("Update").Invoke(appTile, new Object[] { UpdateTileData });
设定Flip Tile属性的方法：
private static void SetProperty(object instance, string name, object value)
{
var setMethod = instance.GetType().GetProperty(name).GetSetMethod();
setMethod.Invoke(instance, new object[] { value });
}
另外在英文的MSDN文档（http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj720574(v=vs.105).aspx）里要求修改WMAppManifest.xml，添加AppExtra节点：
而且说明添加后在vs2010里会编译报错，只有VS2012才能顺利通过，如果在vs2010中使用的话需要先编译生成xap，然后解压出WMAppManifest.xml，修改后再重新打包进去…
但是这段说明在中文版的MSDN文档（http://msdn.microsoft.com/zh-cn/library/windowsphone/develop/jj720574(v=vs.105).aspx）里被删除了
而且我在vs2010中测试那段代码加和不加没什么区别…难道是beta版的时候的要求么？
最后看看效果：
