Perform UI operations before application goes into background

Question

I would like to perform some UI Operations before an application goes into the background ..

UIApplicationDidEnterBackgroundNotification

just doesn't cut it .. I have a MPMoviePlayerController streaming an m3u8 file and i need to pause this video before the application goes into the background mainly because ..
If i do tap on the home button while the video is playing and come into the foreground again ..

The buffered stream of the video is lost and the video plays in a buggy manner and strangely this happens only on iPhone and not iPad ..
so i am hoping to work around this and pause the video before it goes into the background ..

Answer 1

The UIApplicationWillResignActiveNotification seems exactly what you're looking for.

Please take a look at this Application Delegate

Or you can even perform task for a finite time after your application enter to background
