Hi, We’ve got the Unified Push Server working on the OpenShift platform. No real issues once we’d understood the point of aliases. We can send notifications quite happily and see whats going on. We use Perl for our backend servers and so we wrote a small Perl interface. If anybody wants the code for the Perl interface let me know and we’ll pass it on. We can’t claim a lot of credit for a simple piece of code :) Anyway, one of edge use-cases would be to delete notification or set of notifications when the app is running but in the background on iOS. We want to do this as the user can receive a high number of notifications (> 10) when the app is in the background. Notifications come in groups and provide traffic updates, so a user may get a new group of 3-4 traffic updates, this new group completely supersedes ANY previous update. Our data is valuable when fresh and useless when over 10 minutes old. Whilst we can simply ignore old notifications, UX testing has shown the users don’t like having old notifications sitting round. We know that the users can delete them individually or delete the lot from the notification drawer OR can simply bring the app out of the background BUT they don’t like doing that. So what we want to do is delete old notifications, we were hoping for the ability to call a JavaScript function with say a parameter to identify notifications by a group or something, but we could accept deleting the lot and inserting local notifications instead. We know that we can send content-available and have stuff pulled from a server in the background. This option is quite difficult for us and has some complexity identifying when the app is not started up. The simplest option is delete some or all of the notifications. Does anybody know if this is possible or any other suggestions? Thanks Rob
