Question

是否可以在AVPlayer中获得播放时间和总播放时间？如果是，我该怎么做？

Answer 1

您可以使用currentItem属性访问当前播放的项目：

AVPlayerItem *currentItem = yourAVPlayer.currentItem;

然后您可以轻松获得所需的时间值

CMTime duration = currentItem.duration; //total time
CMTime currentTime = currentItem.currentTime; //playing time

Answer 2

_audioPlayer = [self playerWithAudio:_audio];
_observer =
[_audioPlayer addPeriodicTimeObserverForInterval:CMTimeMake(1, 2)
                                           queue:dispatch_get_main_queue()
                                      usingBlock:^(CMTime time)
                                      {
                                          _progress = CMTimeGetSeconds(time);
                                      }];

Swift 3

let currentTime:Double = player.currentItem.currentTime().seconds

您可以通过访问seconds的{{1}}属性来获取当前时间的秒数。这将返回表示时间秒的currentTime()。然后，您可以使用此值构建可读时间以呈现给您的用户。

首先，提供一个方法来返回您将向用户显示的Double的时间变量：

H:mm:ss

接下来，将上面检索到的值转换为可读字符串的方法：

func getHoursMinutesSecondsFrom(seconds: Double) -> (hours: Int, minutes: Int, seconds: Int) {
    let secs = Int(seconds)
    let hours = secs / 3600
    let minutes = (secs % 3600) / 60
    let seconds = (secs % 3600) % 60
    return (hours, minutes, seconds)
}

现在，使用之前的计算更新UI：

func formatTimeFor(seconds: Double) -> String {
    let result = getHoursMinutesSecondsFrom(seconds: seconds)
    let hoursString = "\(result.hours)"
    var minutesString = "\(result.minutes)"
    if minutesString.characters.count == 1 {
        minutesString = "0\(result.minutes)"
    }
    var secondsString = "\(result.seconds)"
    if secondsString.characters.count == 1 {
        secondsString = "0\(result.seconds)"
    }
    var time = "\(hoursString):"
    if result.hours >= 1 {
        time.append("\(minutesString):\(secondsString)")
    }
    else {
        time = "\(minutesString):\(secondsString)"
    }
    return time
}

Answer 4

使用Swift 4.2，使用它;

let currentPlayer = AVPlayer()
if let currentItem = currentPlayer.currentItem {
    let duration = currentItem.asset.duration
}
let currentTime = currentPlayer.currentTime()

Answer 5

     AVPlayerItem *currentItem = player.currentItem;
     NSTimeInterval currentTime = CMTimeGetSeconds(currentItem.currentTime);
     NSLog(@" Capturing Time :%f ",currentTime);

Answer 6

夫特：

let currentItem = yourAVPlayer.currentItem

let duration = currentItem.asset.duration
var currentTime = currentItem.asset.currentTime

    self.playerItem = AVPlayerItem(url: videoUrl!)
    self.player = AVPlayer(playerItem: self.playerItem)

    self.player?.addPeriodicTimeObserver(forInterval: CMTimeMakeWithSeconds(1, 1), queue: DispatchQueue.main, using: { (time) in
        if self.player!.currentItem?.status == .readyToPlay {
            let currentTime = CMTimeGetSeconds(self.player!.currentTime())

            let secs = Int(currentTime)
            self.timeLabel.text = NSString(format: "%02d:%02d", secs/60, secs%60) as String//"\(secs/60):\(secs%60)"

    })
}

Answer 8

可以直接查询播放器，找到当前正在播放的AVPlayerItem的当前时间。时间存储在 CMTime Struct 中，以便于转换为各种比例，例如 10th of sec、100th of a sec 等在大多数情况下，我们需要以秒为单位表示时间，因此以下内容将向您展示您想要的

let currentTimeInSecs = CMTimeGetSeconds(player.currentTime())

Answer 9

Swift 4.2：

let currentItem = yourAVPlayer.currentItem
let duration = currentItem.asset.duration
let currentTime = currentItem.currentTime()

Answer 10

迅速5：如果您想要平滑的进度条，则Timer.scheduledTimer似乎比addPeriodicTimeObserver更好

static public var currenTime = 0.0
static public var currenTimeString = "00:00"

        Timer.scheduledTimer(withTimeInterval: 1/60, repeats: true) { timer in

            if self.player!.currentItem?.status == .readyToPlay {

                let timeElapsed = CMTimeGetSeconds(self.player!.currentTime())
                let secs = Int(timeElapsed)
                self.currenTime = timeElapsed
                self.currenTimeString = NSString(format: "%02d:%02d", secs/60, secs%60) as String


                print("AudioPlayer TIME UPDATE: \(self.currenTime)    \(self.currenTimeString)")
            }
        }
