Best way to implement MPMoviePlayer timeout

问题

I have MPMoviePlayer that load movie from stream. I implemented timeout on 15 seconds with timers. But is there maybe some other better way to implement timeout without timer?

回答1:

Register for the MPMoviePlayerLoadStateDidChangeNotification. Within its handler, check the current loadstate and mask out the MPMovieLoadStateStalled.

- (void)MPMoviePlayerLoadStateDidChange:(NSNotification *)notification
{
    //is the player stalled, hence possibly starving?
    if ((movieController_.loadState & MPMovieLoadStateStalled) == MPMovieLoadStateStalled)
    {  //yes->do something
       NSLog(@"hey there, I am starving to death here");
    }
}

You may want to register a timer within the upper if-clause - e.g. 10seconds. Once that baby runs out of time without further state-changes, do something to terminate / skip the video playback.

I'm not sure but i think it's possible to use performSelector as timer?

[self performSelector:@selector(checkTimeout:) withObject:theMovie afterDelay:15];

and then check for the movie state.
