如何在AVPlayer中獲得當前播放時間和總播放時間？

Question

AVPlayer有可能獲得播放時間和總播放時間嗎？如果是的話，我該怎麼做？

Answer 1

您可以通過使用currentItem屬性訪問當前播放的項目：

AVPlayerItem *currentItem = yourAVPlayer.currentItem; 

然後你就可以很容易地得到所要求的時間值

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); 
             }]; 

Answer 3

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

Answer 4

斯威夫特：

let currentItem = yourAVPlayer.currentItem 

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

Answer 5

用Swift 2.0，用這個;

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

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

您可以通過訪問currentTime()的seconds財產得到您的當前時間的秒數。這將返回代表時間秒數的Double。然後你可以使用這個值來構建一個可讀的時間來呈現給你的用戶。

首先，包括對返回的時間變量H:mm:ss，你將顯示給用戶的方法：

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) 
} 

接下來，將你上述檢索的值轉換成可讀的字符串方法：

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 
} 

現在，更新與之前計算的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) 
    } 
}
