iPhone programming question:
Is it possible to wakeup/resume iPhone application from background mode to foreground mode programmatically?
I have a long-running background task, which is being launched in applicationDidEnterBackground method of UIApplicationDelegate.
I need to make my application active/visible using some code inside this background task.
Is this possible?
Thanks.
This is not possible. However, you can fire a local notification to alert the user.
