我如何在AVPlayer中获得当前的播放时间和总播放时间?

Is it possible get playing time and total play time in AVPlayer? If yes, how can I do this?

是否有可能在AVPlayer获得播放时间和总播放时间?如果是，我怎么做呢?

You can access currently played item by using currentItem property:

您可以使用当前播放的物品使用货币属性:

AVPlayerItem *currentItem = yourAVPlayer.currentItem;

Then you can easily get the requested time values

然后您可以很容易地获得所请求的时间值

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

#2

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

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

You can get the seconds of your current time by accessing the seconds property of the currentTime(). This will return a Double that represents the seconds in time. Then you can use this value to construct a readable time to present to your user.

通过访问currentTime()的seconds属性，可以获得当前时间的秒。这将返回一个表示时间秒数的双精度浮点数。然后您可以使用这个值来构造一个可读的时间来呈现给您的用户。

First, include a method to return the time variables for H:mm:ss that you will display to the user:

首先，包含一个方法来返回H:mm:ss的时间变量，您将显示给用户:

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)
}

Next, a method that will convert the values you retrieved above into a readable string:

接下来，将上面检索到的值转换为可读字符串的方法:

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
}

Now, update the UI with the previous calculations:

现在，使用前面的计算更新UI:

func updateTime() {
    // Access current item
    if let currentItem = player.currentItem {
        // Get the current time in seconds
        let playhead = currentItem.currentTime().seconds
        let duration = currentItem.duration.seconds
        // Format seconds for human readable string
        playheadLabel.text = formatTimeFor(seconds: playhead)
        durationLabel.text = formatTimeFor(seconds: duration)
    }
}

With Swift 2.0, use this;

使用Swift 2.0，请使用这个;

let currentPlayerItem = AVPlayer.currentItem
let duration = currentPlayerItem?.asset.duration
var currentTime = AVPlayer.currentTime()

#5

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

#6

Swift:

迅速:

let currentItem = yourAVPlayer.currentItem

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