Set up notifications

The player can listen for a range of events that indicate the state of the player.

Assuming that PTMediaPlayer is a property of the client player, self.player in the following example represents the PTMediaPlayer instance. The following example implements the addObservers method that are shown in the PTMediaPlayer set up instructions and includes most of the notifications:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerStatusChange:)
      name:PTMediaPlayerStatusNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerNotification:)
      name:PTMediaPlayerNewNotificationEntryAddedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerTimeChange:)
      name:PTMediaPlayerTimeChangeNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerItemPlayStarted:)
      name:PTMediaPlayerPlayStartedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerItemPlayCompleted:)
      name:PTMediaPlayerPlayCompletedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerItemTimelineChanged:)
      name:PTMediaPlayerTimelineChangedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerItemMediaSelectionOptionsAvailable:)
      name:PTMediaPlayerMediaSelectionOptionsAvailableNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerAdBreakStarted:)
      name:PTMediaPlayerAdBreakStartedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerAdBreakCompleted:)
      name:PTMediaPlayerAdBreakCompletedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerAdPlayStarted:)
      name:PTMediaPlayerAdStartedNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerAdPlayProgress:)
      name:PTMediaPlayerAdProgressNotification object:self.player];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerAdPlayCompleted:)
      name:PTMediaPlayerAdCompletedNotification object:self.player];

iOS notifications

ThePTMediaPlayerNotifications class lists the notifications that the TVSDK dispatches to your player.

Sample handlers for notifications

The following code snippets illustrate some of the ways you can use notifications.

Fetch the PTAdBreak instance using PTMediaPlayerAdBreakKey:

 - (void) onMediaPlayerAdBreakStarted:(NSNotification *) notification {
   // Fetch the PTAdBreak instance using PTMediaPlayerAdBreakKey
   PTAdBreak *adBreak = [notification.userInfo objectForKey:PTMediaPlayerAdBreakKey];
   ...
   ...
}

Set subtitlesOptions and audioOptions:

 - (void) onMediaPlayerItemMediaSelectionOptionsAvailable:(NSNotification \*) notification {
   //SubtitlesOptions and audioOptions are set and accessible now.
   NSArray* subtitlesOptions = self.player.currentItem.subtitlesOptions;
   NSArray* audioOp tions = self.player.currentItem.audioOptions;
   ...
   ...
}

Fetch the PTAd instance using PTMediaPlayerAdKey:

 - (void) onMediaPlayerAdPlayStarted:(NSNotification \*)  notification {
   // Fetch the PTAdinstance using PTMediaPlayerAdKey
   PTAd *ad = [notification.userInfo objectForKey:PTMediaPlayerAdKey];
   ...
   ...
}
