磁贴更新

Question

就一个简单的 磁贴网络轮询功能

            List<Uri> tileUriList = new List<Uri>();
            tileUriList.Add(new Uri("http://www.testPage.com/tile/TileFile1.xml"));
            tileUriList.Add(new Uri("http://www.testPage.com/tile/TileFile2.xml"));
            tileUriList.Add(new Uri("http://www.testPage.com/tile/TileFile3.xml"));
            tileUriList.Add(new Uri("http://www.testPage.com/tile/TileFile4.xml"));
            tileUriList.Add(new Uri("http://www.testPage.com/tile/TileFile5.xml"));
            TileUpdateManager.CreateTileUpdaterForApplication().StartPeriodicUpdateBatch(tileUriList, PeriodicUpdateRecurrence.HalfHour);

本机运行，OK。测试机OK，挪到Surface上，死活不行，磁贴半天才动一下，根本不像是5个磁贴在轮转，反而像是一个磁贴显示10分钟（甚至更长），再换一个。有人能给我解释一下吗！！！烦躁啊！

（注：轮询连接地址在surface的IE中打开是可以访问的，包括图像文件也是可以访问的）

Answer 4

To retrieve up to five notifications from an array of up to five unique Uniform Resource Identifiers (URIs) to populate the tile's notification queue, you must first enable the tile's notification queue by calling EnableNotificationQueue. Periodic updates will continue until they are explicitly stopped or your app is uninstalled. Technically, you only have to do that once. But, the Guidelines and checklist for periodic updates states

"Call the StartPeriodicUpdate or StartPeriodicUpdateBatch method each time your app is launched or brought into focus. This ensures that the tile content will be updated each time the user launches or switches to the app."

According to that, App launch and App resume are good candidates for a call to StartPeriodicUpdate.

Adding Live tiles to the desktop using c# code: 

List<Uri> StoryUrls = new List<Uri>();
        StoryUrls .Add(new Uri("tiles.xml"));
        TileUpdateManager.CreateTileUpdaterForApplication().EnableNotificationQueue(true);
        TileUpdateManager.CreateTileUpdaterForApplication().Clear();
        TileUpdateManager.CreateTileUpdaterForApplication().StartPeriodicUpdateBatch(StoryUrls, PeriodicUpdateRecurrence.HalfHour);

tiles.xml should follow microsoft format show in step 5 Here

here are some good posts for refference, http://mikaelkoskinen.net/winrt-example-of-using-periodic-notifications-for-live-tiles/, http://code.msdn.microsoft.com/windowsapps/push-and-periodic-de225603
