【 Swift】AVPlayerで動画を指定時間まで進める方法

Last updated at Posted at 2016-10-12

AVFoundationのAVPlayerで動画を指定時間まで進めたいことがありましたので、
備忘の為投稿します!!よければご参考にしてください。

#以下はNG
videoPlayer.seekToTime(CMTimeMakeWithSeconds(Float64(seekBar.value), Int32(NSEC_PER_SEC)))

#以下を使いましょう
videoPlayer.seekToTime(CMTimeMakeWithSeconds(Float64(seekBar.value), Int32(NSEC_PER_SEC)), toleranceBefore: kCMTimeZero, toleranceAfter: kCMTimeZero)

理由は、UISliderなどでシークで早送りする際に上の方法だと、滑らかに動画が早送りされない。(飛び飛びに早送りされてしまう)
