Tap Multiple Times to seek bar when playing.

[gilwang0704]

I wonder if I may submit issues for this.
Anyway video screen is frozen and seek bar looks good.
Please check following code.(- (void)scrub:(id)sender )
int32_t timeScale = self.player.currentItem.asset.duration.timescale;
CMTime time = CMTimeMakeWithSeconds(self.scrubberControlSlider.value, timeScale);
[self.player seekToTime:time toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero];
