Question

我正在开发App，我想在其中显示当前播放时间和视频总时间。我得到了总时间。现在显示当前的播放时间将调用哪种方法。有人可以帮忙吗？我用过avplayer。这是代码：

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [self.avplayer pause];
    self.avplayer = [AVQueuePlayer playerWithURL:[NSURL URLWithString:@""]];
    self.avplayer = nil;
}
- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:NO];

    AVPlayerItem *currentItem = self.avplayer.currentItem;
    CMTime duration = currentItem.duration; //total time
    CMTime currentTime = currentItem.currentTime; //playing time

    NSUInteger durationSeconds = (long)CMTimeGetSeconds(duration);
    NSUInteger minutes = floor(durationSeconds % 3600 / 60);
    NSUInteger seconds = floor(durationSeconds % 3600 % 60);
    NSString *time = [NSString stringWithFormat:@"%02ld:%02ld", (unsigned long)minutes, (unsigned long)seconds];
    NSLog(@"Time|%@", time);
    lblTotaltime.text = time;


    NSUInteger durationSeconds1 = (long)CMTimeGetSeconds(currentTime);
    NSUInteger minutes1 = floor(durationSeconds1 % 3600 / 60);
    NSUInteger seconds1 = floor(durationSeconds1 % 3600 % 60);
    NSString *time1 = [NSString stringWithFormat:@"%02ld:%02ld", (unsigned long)minutes1, (unsigned long)seconds1];
    NSLog(@"Time|%@", time1);
    lblRemaningTime.text = time1;
}

#pragma mark PlayerMethods
- (void)itemDidFinishPlaying:(NSNotification *)notification {
    AVPlayerItem *player = [notification object];
    [player seekToTime:kCMTimeZero];

}
- (void)playerItemDidReachEnd:(NSNotification *)notification {

    AVPlayerItem *p = [notification object];
    [p seekToTime:CMTimeMake(0, 3)];
}

- (void)playerStartPlaying
{
    [self.avplayer play];
}

您可以使用currentItem

使用AVPlayerItem属性来获取当前播放时间

AVPlayerItem *getcurrentItem = yourAVPlayerName.currentItem;

获取总持续时间

CMTime fullDuration = getcurrentItem.duration;

获取当前时间

CMTime playercurrentTime = getcurrentItem.currentTime;

替代

NSTimeInterval playercurrentTime = CMTimeGetSeconds(getcurrentItem.currentTime);
NSLog(@" get current Time of video :%f ",playercurrentTime);

Avplayer视频播放方法
