[Aerogear-users] Unified Push Server - Anyway to delete notifications when in background?

Hi Rob,

Like Matthias already told you on Android managing notifications and
changing how they look is much simpler then on iOS. On iOS you can cancel
all the remote notifications, but not some.

Corrine had this idea: send your notifications as 'background
notifications' (e.g. 'content-available' flag set) then your app will be
notified, but nothing will show up in the Notification area. You can use
local notifications to create the notification in the notification area,
because these you can cancel. You decide how they show up and even group
them. The cordova plugin to create local notifications is called
'cordova-plugin-local-notifications' [1]

So you will have to deal with the complexities of background notifications
for this to work, but to determine if the app is in the foreground when the
background notification arrives there is a boolean on the notification to
help [2]

Although I must advise you sending large volumes of messages might not be a
great way to use push notifications, it's meant to inform the user that
something important has happened it should be personal and engage the
users. Users could also opt to turn off the push notifications so you can't
use it to transfer data.

Hope this helps
