最近添加/更改的内容Recently added/changed

  1. 应用程序不工作App won't work

    如果创建的应用在未发出警告的情况下停止工作,则可能是因为在过去六个月的时间里没有对其进行更新或重新发布。If an app you created stops working without warning, it might be because you haven't updated or re-published it in the last six months. 若要解决此问题,更新和/或重新发布应用以使其与最新版本的 PowerApps 同步,并确保在最后一次发布时起的六个月内继续更新和/或重新发布该应用。To resolve this issue, update and/or re-publish your app to sync it with the latest version of PowerApps, and then make sure that you continue to update and/or re-publish the app within six months of last publishing it.

  2. “数据表”控件Data Table control

    如果复制并粘贴“数据表”控件,且它的 Items 属性设置为包含 Filter 函数的公式,新“数据表”控件的 Items 属性的公式以包含 _1 后缀的字段名称结尾。If you copy and paste a Data Table control for which the Items property is set to a formula that contains a Filter function, the formula for the Items property on the new Data Table control ends up with field names that contain a _1 suffix. 这就会导致字段名称无效,且数据表不显示任何数据。This makes the field names invalid and results in no data showing up in the data table. 若要解决此问题,请在复制此控件前,先确认 Filter 函数从数据源中引用的任何字段都不与“数据表”控件中的列同名。To work around this issue, before you copy the control, confirm that the Filter function doesn't reference any field in the data source that has the same name as a column in the Data Table control. 如果是,请重命名“数据表”控件中的列。If it does, rename the column in the Data Table control. 也可以从无效的字段名称中删除 _1 后缀,让它们与实体中的名称保持一致。Alternatively, remove the _1 suffix from the invalid field names so they match the names in the entity.

  3. 适用于 Windows 的 PowerApps Studio 中的照相机控件Camera controls in PowerApps Studio for Windows

    如果添加照相机控件或打开使用照相机控件的应用,适用于 Windows 的 PowerApps Studio 可能会发生故障。PowerApps Studio for Windows may crash if you add a camera control or open an app that uses a camera control. 为了避免此问题发生,请在添加或使用照相机控件时,使用适用于 Web 的 PowerApps StudioTo avoid this problem, use PowerApps Studio for web when adding or using a camera control.

  4. Android 设备上的版本 2.0.700Release 2.0.700 on Android devices

    如果在 Android 设备上安装版本 2.0.700,然后无法打开应用(或应用停止响应),请先卸载 PowerApps 并重启设备,再重新安装 PowerApps。If you install release 2.0.700 on an Android device and then can't open apps (or an app stops responding), uninstall PowerApps, restart the device, and then reinstall PowerApps.

  5. 打开应用时库为“空”"Empty" gallery when opening an app

    通过数据自动生成应用,保存应用,然后将其重新打开,浏览库时可能不会立即显示数据。If you generate an app automatically from data, save the app, and then reopen it, the browse gallery might not immediately show any data. 若要解决此问题,请在搜索框中至少键入一个字符,然后删除键入的文本。To resolve this issue, type at least one character in the search box, and then delete the text that you typed. 这样库就能按预期方式显示数据了。The gallery will then show data as expected.

  6. 在 Windows 8.1 上升级 PowerAppsUpgrading PowerApps on Windows 8.1

    如果安装 PowerApps 的计算机上运行的是 Windows 8 或 Windows 8.1,请打开 Windows 应用商店应用并使之处于活动状态,使用“设置”超级按钮检查更新程序,然后安装更新程序。If you install PowerApps on a computer that’s running Windows 8 or Windows 8.1, keep the Windows Store app open and active, use the Settings charm to check for updates, and then install them.

  7. 自定义连接器和 Common Data ServiceCustom connectors and the Common Data Service

    如果使用 PowerApps 生成号 2.0.540 或更低版本创建的应用依赖 Common Data Service 中的数据库和至少一个位于不同环境中的自定义连接器,需要将连接器部署到与数据库相同的环境中,并将应用更新为使用新连接器。If an app created using PowerApps build 2.0.540 or earlier relies on a database in the Common Data Service and at least one custom connector in a different environment, you’ll need to deploy the connector to the same environment as the database and update the app to use the new connector. 否则,将出现一个对话框,通知用户找不到此 API。Otherwise, a dialog box will notify users that the API was not found. 有关详细信息,请参阅环境概述For more information, see the overview of environments.

  8. 在 Windows 8.1 上运行应用Running an app on Windows 8.1

  9. 带空格的列名称Column names with spaces

    如果使用的 SharePoint 列表或 Excel 表的列名称包含空格,PowerApps 会将空格替换为“_x0020_”。If you're using a SharePoint list or an Excel table in which a column name contains a space, PowerApps will replace it with "_x0020_". 例如,如果 SharePoint 或 Excel 中的“Column Name”在数据布局中显示或用于公式,它将在 PowerApps 中显示为“Column_x0020_Name”。For example, "Column Name" in SharePoint or Excel will appear as "Column_x0020_Name" in PowerApps when displayed in the data layout or used in a formula.
