iOS Contextual Navigation Toolbar

📘

Unlike Android devices iPhones and iPads do not have a built-in back button, which can make navigating your website from within your app challenging. This feature provides a native navigation toolbar that shows on the bottom of the device screen dependent on navigation history and page URL. By default, the toolbar will include a Back button but it can be customized to also show with Forward and Refresh buttons.

By default, the Contextual Navigation Toolbar will be displayed whenever there is a page in the webview history that can be returned to. This functionality makes it easier for users to navigate your app in a similar manner to your website.

Back Button Back, Refresh, and Forward buttons

Configuration

By default, the Contextual Navigation Toolbar will show a back button with a text label "< Back". You may edit the navigation configuration object in appConfig.json to:

  • Add a Forward button
  • Add a Refresh button
  • Change the toolbar visibility settings to show based on history
    • Only show when there is a page in history (default:) "visibilityByBackButton": "backButtonActive"
    • Always show regardless of history: "visibilityByBackButton": "always"
  • Change the toolbar visibility to only show on all pages or specific pages
    • Show on all pages displayed within the app: "visibilityByPages": "allPages"
    • Only show on specific pages based on regexes provided: "visibilityByPages": "specificPages"
  • Change the visibility of the buttons based on specific pages
  • Change the display of the Back and Forward buttons to show without a text label or with a custom test label
