Windows 8 Live Tile多久更新一次? [英] How often can a Windows 8 Live Tile be updated?

问题描述

我是Windows 8的新手，我对Live Tiles特别感兴趣.

I'm new to Windows 8 and I'm particularly interested in Live Tiles.

我想知道-应用程序多久可以更新一个实时图块?例如，是否可以创建一个以秒为单位的时钟?

I was wondering - How frequently can an app update a live tile? For example, is it possible to create a clock with seconds?

推荐答案

Live Tile每秒更新太频繁了.

A Live Tile update every second is far too frequent.

有关Live Tiles的MSDN指南文档确实可以并未对可更新图块的频率设置明确的限制，但确实对更新频率提出了一些建议.对于内容变化非常频繁的应用，预期的最高平均频率约为15分钟.一些摘录摘录:

The MSDN guidelines for Live Tiles documentation does not set explicit limits on how often a tile can be updated, but does make a few recommendations about the frequency of updates. For an app with very frequently changing content, the highest average frequency expected is approximately 15 minutes. A few choice excerpts:

对于非个性化内容(例如天气更新)，我们建议每30分钟更新一次磁贴.这样一来，您的磁贴就可以保持最新状态，而不会淹没用户.

For nonpersonalized content, such as weather updates, we recommend that the tile be updated no more than once every 30 minutes. This allows your tile to feel up-to-date without overwhelming your user.

例如，繁忙的社交媒体应用程序可能每15分钟更新一次，气象应用程序每两个小时更新一次，新闻应用程序一天几次更新，每日一次的要约应用程序每天一次，而杂志应用程序每月一次.

For example, a busy social media app might update every 15 minutes, a weather app every two hours, a news app a few times a day, a daily offers app once a day, and a magazine app monthly.

缺少时钟更新建议，因为这不是Live Tile更新的预期目的.商店中显示其磁贴时间的应用程序创造性地使用计划的磁贴通知(打算用于一次日历事件)，或者频繁地将通知推送到WNS(Windows推送通知服务).前者非常困难，即使不是不可能的，即使以每分钟的精确度来正确实现(请参阅应用程序评论)，后者也很容易被标记为滥用并受到WNS的限制.

Recommendations for clock updates are absent, as that isn't an intended purpose for Live Tile updates. The apps in the store showing the time on their tile use scheduled tile notifications creatively (intended to be used for one-time calendar events), or frequently push notifications to WNS (Windows Push Notifications Service). The former is very tough, if not impossible, to implement correctly even for per-minute precision (see app reviews), and the latter is prone to being flagged as abuse and throttled by WNS.
