Backgrounding problems when issuing print jobs. #3
Description
Currently, the application does not allocate a background task when sending a print job. As a result, problems can arise if the user backgrounds the app when the 'Please wait...' buttonless alert is showing:
- Sometimes the "Unable to connect." alert will show up. This is because the application thinks the network request timed out since it wasn't alive to handle the response.
- If the "Unable to connect" alert doesn't show up, all of the bar button items and tab bar icons will appear grayed out, as if the alertview was still active and showing the dimming view. The "Log in" button will also be unresponsive.
- This will also prevent starting the background task responsible for polling the job status for notification purposes.
Also: Reconsider name of "PrintRequestDidSendNotification". This notification is posted when a request from a print job is successful (i.e. The application POSTs to /jobs and gets a response)
