Mostrar la hora actual y el tiempo restante

Puede mostrar el tiempo actual y el tiempo restante del contenido que se está reproduciendo.

1. Para implementar una pantalla que muestre el tiempo actual y el tiempo restante del contenido activo, utilice el siguiente código de ejemplo:

      // 1. Register for the PTMediaPlayerTimeChangeNotification
      [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onMediaPlayerTimeChange:)
        name:PTMediaPlayerTimeChangeNotification object:self.player];
   
      ...
   
      // 2. Create labels for displaying current and remaining time
      _timeCurrentLabel = [[UILabel alloc] initWithFrame:CGRectMake(50.0, 16.0, 50.0, 21.0)];
      _timeCurrentLabel.text = @"00:00:00";
      _timeCurrentLabel.font = [UIFont boldSystemFontOfSize:12.0];
      _timeCurrentLabel.numberOfLines = 1;
      _timeCurrentLabel.textAlignment = UITextAlignmentCenter;
      _timeCurrentLabel.backgroundColor = [UIColor clearColor];
      _timeCurrentLabel.textColor =
        [UIColor colorWithRed:209.0/255.0 green:209.0/255.0 blue:209.0/255.0 alpha:1.0];
      [self addSubview:_timeCurrentLabel];
   
      _timeRemainingLabel = [[UILabel alloc] initWithFrame:CGRectMake(485.0, 16.0, 50.0, 21.0)];
      _timeRemainingLabel.text = @"00:00:00";
      _timeRemainingLabel.font = [UIFont boldSystemFontOfSize:12.0];
      _timeRemainingLabel.numberOfLines = 1;
      _timeRemainingLabel.textAlignment = UITextAlignmentCenter;
      _timeRemainingLabel.backgroundColor = [UIColor clearColor];
      _timeRemainingLabel.textColor =
        [UIColor colorWithRed:209.0/255.0 green:209.0/255.0 blue:209.0/255.0 alpha:1.0];
   
      ...
   
      // 3. This method is called whenever the player time changes
      (PTMediaPlayerTimeChangeNotification) - (void) onMediaPlayerTimeChange:(NSNotification *)notification {
          //The seekable range provides the playback range of a stream
          CMTimeRange seekableRange = self.player.seekableRange;
   
          //Verify if the seekableRange is a valid CMTimeRange
          if (CMTIMERANGE_IS_VALID(seekableRange)) {
              double  duration = CMTimeGetSeconds(seekableRange.duration);
              double currentTime = CMTimeGetSeconds(self.player.currentItem.currentTime);
              if (CMTIME_IS_INDEFINITE(self.player.currentItem.duration)) {
                  //If the duration is indefinite then the content is live.
                  [_timeCurrentLabel setText:[NSString stringWithFormat:@"--:--"]];
                  [_timeRemainingLabel setText:[NSString stringWithFormat:@"Live"]];
              }
              else {
                  [_timeCurrentLabel setText:[self timeFormatter:currentTime]];
                  [_timeRemainingLabel setText:[self timeFormatter:(duration - currentTime)]];
              }
          }
      }
   

2. Para implementar una pantalla que muestre el progreso de un anuncio y el tiempo restante, utilice el siguiente código de ejemplo:

      double adBreakDurationLeft;
      double adBreakDuration;
      float currentAdPosition;
      (void)onMediaPlayerAdBreakStarted:(NSNotification *) notification
      {
      PTAdBreak *adBreak = [notification.userInfo objectForKey:PTMediaPlayerAdBreakKey];
      self.adBreakDuration = CMTimeGetSeconds(adBreak.range.duration);
      self.adBreakDurationLeft = self.adBreakDuration;
      }
      (void)onMediaPlayerAdBreakCompleted:(NSNotification *) notification
      {
      self.adBreakDuration = 0.0f;
      self.adBreakDurationLeft = 0.0f;
      }
      (void)onMediaPlayerAdPlayStarted:(NSNotification *) notification
      {
      self.currentAdPosition = 0;
      }
      (void)onMediaPlayerAdPlayProgress:(NSNotification *) notification
      {
      PTAd *ad = [notification.userInfo objectForKey:PTMediaPlayerAdKey];
      CMTime progress = [(NSValue *)[notification.userInfo objectForKey:PTMediaPlayerAdProgressKey] CMTimeValue];
      if (ad != nil) { // remaining ad playback time in milliseconds self.currentAdPosition = CMTimeGetSeconds(progress); double timeLeft = self.adBreakDurationLeft - (double)self.currentAdPosition; float currentprogress = 1.0f - (timeLeft/self.adBreakDuration); }
      }
      (void)onMediaPlayerAdPlayCompleted:(NSNotification *) notification
      {
      PTAd *ad = [notification.userInfo objectForKey:PTMediaPlayerAdKey];
      self.adBreakDurationLeft = self.adBreakDurationLeft - ad.primaryAsset.duration;
      }
