NSDate和AVPlayerItem.currentTime-Java 学习之路

我知道有很多主题，但我找不到解决问题的方法 .

我有一个AVPlayerItem，我希望currentTime属性（CMTime）转换为我的音乐播放器的可读格式 .

这是我的代码：

NSDate *seconds = [[NSDate alloc] initWithTimeIntervalSinceNow:CMTimeGetSeconds(self.playerItem.currentTime)];

NSDateFormatter *timeFormatter = [[NSDateFormatter alloc] init];
[timeFormatter setDateFormat:@"HH:mm:ss"];

self.currentTimeLabel.text = [NSString stringWithFormat:@"%@", [timeFormatter stringFromDate:seconds]];

它有效，但它增加了1小时的播放时间 . 我怎么能减去那个小时？

谢谢！

试试这段代码，

SWIFT代码：

delclare

var playerVal = AVPlayer()

然后在你想要的地方调用以下方法，

func updateTime() {

        let currentTime = Float(CMTimeGetSeconds(playerVal.currentTime()))
        let minutes = currentTime/60
        let seconds = currentTime - minutes * 60

        startValue.text = NSString(format: "%.2f:%.2f", minutes,seconds) as String

    }

objective-C代码：

delclare

AVPlayer playerVal;

然后在你想要的地方调用以下方法，

- (void)updateTime {
    Float currentTime = CMTimeGetSeconds([playerVal currentTime]);
    Float minutes = currentTime/60;
    Float seconds = (currentTime - minutes) * 60;
    startValue.text = [NSString stringWithFormat:@"%.2f:%.2f", minutes,seconds];
}

它为我工作，希望它有所帮助

thx，我稍微改进了一下：

float currentTime = CMTimeGetSeconds([self.audioStreamPlayer currentTime]);

int seconds = (int) currentTime;
int minutes = (int) currentTime/60;
int hours = (int) ((currentTime/60)/60);

NSString *hoursString = [NSString stringWithFormat:@"%d",hours];
NSString *minutesString = [NSString stringWithFormat:@"%d",minutes];
NSString *secondsString = [NSString stringWithFormat:@"%d",seconds % 60];

if (hoursString.length == 1) {
    hoursString = [NSString stringWithFormat:@"0%d", hours];
}
if (minutesString.length == 1) {
    minutesString = [NSString stringWithFormat:@"0%d",minutes];
}
if (secondsString.length == 1) {
    secondsString = [NSString stringWithFormat:@"0%d", seconds % 60];
}



self.currentTimeLabel.text = [NSString stringWithFormat:@"%@:%@:%@", hoursString, minutesString, secondsString];

作品！
