我有滑块,点击手势,playerNODE
。当我触摸滑块上的某个位置时,我会通过点击手势获取滑块的位置。我想改变AVAudioPlayerNode
游戏时间。播放时间必须是滑块的位置。
func updateProgressBarWithGesture(_ sender: UITapGestureRecognizer) {
songPlayer.pause()
songRecorderPlayer.pause()
videoPlayer.pause()
let time = sender.location(in: sliderView).x / sliderView.frame.width
songProgressSlider.value = Float(time)
let totalTime = songRecorderPlayer.duration
songPlayer.currentTime = TimeInterval(time * CGFloat(totalTime))
songRecorderPlayer.currentTime = TimeInterval(time * CGFloat(totalTime))
let second = time * CGFloat(songRecorderPlayer.duration)
let videoTime = CMTime.init(value: CMTimeValue(second), timescale: 1)
videoPlayer.seek(to: videoTime)
print(" ")
print("Song Player: ",songPlayer.currentTime)
print("Song Recorder Player: ",songRecorderPlayer.currentTime)
print("Video Player: ",videoTime)
if playerNODE.isPlaying{
playerNODE.pause()
playerNODE.reset()
let seekTime = TimeInterval(time * CGFloat(totalTime))
let startingFrame = seekTime * audioFile.processingFormat.sampleRate
let frameCount: AVAudioFrameCount = (AVAudioFrameCount)(Double(audioFile.length) - startingFrame)
playerNODE.scheduleSegment(audioFile, startingFrame: AVAudioFramePosition(startingFrame), frameCount: frameCount, at: nil, completionHandler: nil)
print("Player Node: ",playerNODE.lastRenderTime!)
playerNODE.play()
songPlayer.play()
videoPlayer.play()
}
}
func updateProgressBar() {
songProgressSlider.value = Float(songRecorderPlayer.currentTime/songRecorderPlayer.duration)
}
