  • onsignal_clearAllNotification.lua for button action

  • onsignal_setSubscription.lua for button action

      local enable = UI.enableSubscripton
      OneSignal.SetSubscription(enable)
  

Note

if you want to display message in a text layer of a page instead of native.showAlert, it can be done with associating notifiedMessage variable to a dynamic text replacement.

when a message is received, open the page with showOverlay function

• Dynamic Text

  • Name: msgTxt
  • associate with notifiedMessage

• Add Button

  • Name: hideBtn
  • external code close_overlay.lua

however, push notification comes anytime, it would be a trouble when the page with the dynamic text is not loaded yet. You may open the page by composer.showOverlay function. For instance, if you want to show the pushed message on page1, use the init code below

• onesignal_init.lua for main.lua

      local composer = require("composer")
  
      function DidReceiveRemoteNotification(message, additionalData, isActive)
              _K.notifiedMessage = message
              composer.showOverlay("views.page01Scene")
      end
  
      OneSignal.DisableAutoRegister()
      OneSignal.Init("b2f7f966-d8cc-11e4-bed1-df8f05be55ba", "703322744261", DidReceiveRemoteNotification)
      OneSignal.EnableInAppAlertNotification(true)
  

• close_overlay.lua

      local composer = require("composer")
      composer.hideOverlay()
  
  

Bookshelf Embedded project

• copy the lines of onesignal_init.lua to main.lua.
• If you use composer.showOverlay, TOC and each book must have a page for displaying a message text and closing button of hydeOverlay
• you setup a setting page of notification in a project as adding plugin.OneSignal as a library described above
• add the plugin to build.settings as described in Part1
