iOS Configuration

The config.xml file controls an app's basic settings that apply across each application and CordovaWebView instance. This section details preferences that only apply to iOS builds. See The config.xml File for information on global configuration options.

• EnableViewportScale (boolean, defaults to false): Set to true to allow a viewport meta tag to either disable or restrict the range of user scaling, which is enabled by default.

    <preference name="EnableViewportScale" value="true"/>
  

  Place a viewport such as the following in the HTML to disable scaling and fit content flexibly within the rendering WebView:

    <meta name='viewport' content='width=device-width, initial-scale=1, user-scalable=no' />
  

• MediaPlaybackRequiresUserAction (boolean, defaults to false): Set to true to prevent HTML5 videos or audios from playing automatically with the autoplay attribute or via JavaScript.

    <preference name="MediaPlaybackRequiresUserAction" value="true"/>
  

• AllowInlineMediaPlayback (boolean, defaults to false): Set to true to allow HTML5 media playback to appear inline within the screen layout, using browser-supplied controls rather than native controls. For this to work, add the webkit-playsinline attribute to any <video> elements.

    <preference name="AllowInlineMediaPlayback" value="true"/>
  

• BackupWebStorage (string, either none, local, or the default cloud): Set to cloud to allow web storage data to backup via iCloud. Set to local to allow only local backups via iTunes sync. Set to none prevent web storage backups.

    <preference name="BackupWebStorage" value="local"/>
  

• TopActivityIndicator (string, defaults to gray): Controls the appearance of the small spinning icon in the status bar that indicates significant processor activity. Valid values are whiteLarge, white, and gray.

    <preference name="TopActivityIndicator" value="white"/>
  

• KeyboardDisplayRequiresUserAction (boolean, defaults to true): Set to false to allow the keyboard to appear when calling focus() on form inputs.

    <preference name="KeyboardDisplayRequiresUserAction" value="false"/>
  

• SuppressesIncrementalRendering (boolean, defaults to false): Set to true to wait until all content has been received before it renders to the screen.

    <preference name="SuppressesIncrementalRendering" value="true"/>
  

• GapBetweenPages (float, defaults to 0): The size of the gap, in points, between pages.

    <preference name="GapBetweenPages" value="0"/>
  

• PageLength (float, defaults to 0): The size of each page, in points, in the direction that the pages flow. When PaginationMode is right to left or left to right, this property represents the width of each page. When PaginationMode is topToBottom or bottomToTop, this property represents the height of each page. The default value is 0, which means the layout uses the size of the viewport to determine the dimensions of the page.

    <preference name="PageLength" value="0"/>
  

• PaginationBreakingMode (string, defaults to page): Valid values are page and column.The manner in which column- or page-breaking occurs. This property determines whether certain CSS properties regarding column- and page-breaking are honored or ignored. When this property is set to column, the content respects the CSS properties related to column-breaking in place of page-breaking.

    <preference name="PaginationBreakingMode" value="page"/>
  

• PaginationMode (string, defaults to unpaginated): Valid values are unpaginated, leftToRight, topToBottom, bottomToTop, and rightToLeft. This property determines whether content in the web view is broken up into pages that fill the view one screen at a time, or shown as one long scrolling view. If set to a paginated form, this property toggles a paginated layout on the content, causing the web view to use the values of PageLength and GapBetweenPages to relayout its content.

    <preference name="PaginationMode" value="unpaginated"/>
