iOS检查是否连接了m3u8流

Question

I use MPMoviePlayerController to play m3u8 stream. But it doesn't support me a method to check if the m3u8 link is working, so if the link is dead I must waiting for MPMoviePlayerController playing a while to make sure that it's not working. In this situation, I want to show an AlertView if the link is dead to keep user from not waiting before send the link to MPMoviePlayerController . Is there any way to do it ?

Try this once..

Normally we check this after some time, for that we can set a time delay

[self performSelector:@selector(movieTimedOut) withObject:nil afterDelay:20.f];

-(void)movieTimedOut
{
     if (!(self.loadState & MPMovieLoadStatePlayable) || !(self.loadState & MPMovieLoadStatePlaythroughOK))
      {
           //AlertView
      }
}
