定期通知更新WIndows 8應用程序中的所有切片大小

Question

我有一個應用程序框架（使用JavaScript），它動態設置實時切片源的URL。在我的代碼中，我有類似於下面的內容，這適用於寬廣的圖塊，但是當我將圖塊大小調整爲「中等」（或「小」）時，實時Feed /更新消失。如果我調整大小，它就可以工作。沒有其他瓷磚設置（它使用默認設置）。

我的問題是：反正是有在同一時間更新所有瓷磚的大小，否則我將不得不建立使用getTemplateContent()和一個完整的XML對象TileUpdater的update()方法？

我現在更新，像這樣的週期性的URL（同樣，這適用於寬瓦）：

var updater = Windows.UI.Notifications.TileUpdateManager.createTileUpdaterForApplication(); 
updater.clear(); 
updater.stopPeriodicUpdate(); 
updater.enableNotificationQueue(true); 
updater.startPeriodicUpdateBatch(
    [ new Windows.Foundation.Uri(feedUrlString) ], 
    Windows.UI.Notifications.PeriodicUpdateRecurrence.halfHour 
); 

Answer 1

要在單個更新更新多個瓷磚尺寸，該更新的XML有效載荷必須包含單個元素每個瓷磚大小。

您可以在SDK中的App tiles and badges sample中看到這一點。例如，場景1演示瞭如何使用（a）C＃NotificationExtensions庫，（b）將XML構建爲字符串，以及（c）使用getTemplateContent。其中一種方法應該適合你。

舉的情況的一個例子（一），這裏是從方案1中的代碼，也有一個註釋說明更多：

// This sample application supports all four tile sizes – small (Square70x70), medium (Square150x150), wide (Wide310x150) and large (Square310x310). 
// This means that the user may have resized their tile to any of these four sizes for their custom Start screen layout. 
// Because an app has no way of knowing what size the user resized their app tile to, an app should include template bindings 
// for each supported tile sizes in their notifications. The only exception is the small (Square70x70) tile size because this size 
// does not support live tile notifications, which is why there are no Square70x70 tile templates. 
// We assemble one notification with three template bindings by including the content for each smaller 
// tile in the next size up. Square310x310 includes Wide310x150, which includes Square150x150. 
// If we leave off the content for a tile size which the application supports, the user will not see the 
// notification if the tile is set to that size. 

// Create a notification for the Square310x310 tile using one of the available templates for the size. 
var tileContent = NotificationsExtensions.TileContent.TileContentFactory.createTileSquare310x310Text09(); 
tileContent.textHeadingWrap.text = "Hello World! My very own tile notification"; 

// Create a notification for the Wide310x150 tile using one of the available templates for the size. 
var wide310x150Content = NotificationsExtensions.TileContent.TileContentFactory.createTileWide310x150Text03(); 
wide310x150Content.textHeadingWrap.text = "Hello World! My very own tile notification"; 

// Create a notification for the Square150x150 tile using one of the available templates for the size. 
var square150x150Content = NotificationsExtensions.TileContent.TileContentFactory.createTileSquare150x150Text04(); 
square150x150Content.textBodyWrap.text = "Hello World! My very own tile notification"; 

// Attach the Square150x150 template to the Wide310x150 template. 
wide310x150Content.square150x150Content = square150x150Content; 

// Attach the Wide310x150 template to the Square310x310 template. 
tileContent.wide310x150Content = wide310x150Content; 

// Send the notification to the application’s tile. 
Windows.UI.Notifications.TileUpdateManager.createTileUpdaterForApplication().update(tileContent.createNotification());
