我正在使用AVAudioPlayer
播放歌曲。我需要进度条并显示歌曲的进度。
我的问题是进度栏进度无法正常工作。在2-3秒内完成进度。
func playMusic() {
do {
player = try AVAudioPlayer(contentsOf: (currentSong?.mediaURL)!)
guard let player = player else { return }
player.prepareToPlay()
player.play()
updater = CADisplayLink(target: self, selector: #selector(self.musicProgress))
updater.frameInterval = 1
updater.add(to: RunLoop.current, forMode: RunLoop.Mode.common)
playButton.setImage(UIImage.init(named: "pause"), for: .normal)
} catch let error as NSError {
print(error.description)
}
}
@objc func musicProgress() {
let normalizedTime = Float(self.player?.currentTime as! Double * 100.0 / (self.player?.duration as! Double) )
self.progressMusic.progress = normalizedTime
}
最佳答案
问题在这里:
let normalizedTime = Float(self.player?.currentTime as! Double * 100.0 / (self.player?.duration as! Double) )
这样,您将获得一个介于
0.0
和100.0
之间的值,但是根据UIProgressView
文档,progress
必须介于0.0
和1.0
之间。尝试let normalizedTime = Float(self.player?.currentTime as! Double / (self.player?.duration as! Double) )
