SeektoTime不能正常工作

Question

为了暂停和恢复视频，我正在使用下面的代码。但它不是从它离开的地方恢复。有人能帮助我吗？

-(void)appEnteredBackground:(NSNotification*)notification {
    [playerViewController.player pause];
    currentTime = [playerViewController.player currentTime];
}

-(void)appEnteredForeground:(NSNotification*)notification {

    if(playerViewController.player.status == AVPlayerStatusReadyToPlay &&
       self.playerViewController.player.currentItem.status ==  AVPlayerItemStatusReadyToPlay) {
       total_duration = self.playerViewController.player.currentItem.duration;
       [self.playerViewController.player.currentItem seekToTime:CMTimeMakeWithSeconds(CMTimeGetSeconds(currentTime),60000)];
       [playerViewController.player play];
    }
}

如果currentTime值保持不变，则需要添加公差部分以从精确秒开始恢复。

[self.playerViewController.player.currentItem seekToTime:CMTimeMakeWithSeconds(CMTimeGetSeconds(currentTime),60000) toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero];
