AVPlayer is fully customizable, unfortunately there are convenient methods in AVPlayer for showing the time line progress bar.

Answer 1

Thanks to iOSPawan for the code! I simplified the code to the necessary lines. This might be more clear to understand the concept. Basically I have implemented it like this and it works fine.

Before starting the video:

__weak NSObject *weakSelf = self;    
[_player addPeriodicTimeObserverForInterval:CMTimeMakeWithSeconds(1.0 / 60.0, NSEC_PER_SEC)
                                      queue:NULL
                                 usingBlock:^(CMTime time){
                                                [weakSelf updateProgressBar];
                                             }];

[_player play];

Then you need to have a method to update your progress bar:

- (void)updateProgressBar
{
    double duration = CMTimeGetSeconds(_playerItem.duration);
    double time = CMTimeGetSeconds(_player.currentTime);
    _progressView.progress = (CGFloat) (time / duration);
}

Answer 2

for timeline i do this

-(void)changeSliderValue {

double duration = CMTimeGetSeconds(self.player.currentItem.duration);

[lengthSlider setMaximumValue:(float)duration];

lengthSlider.value = CMTimeGetSeconds([self.player currentTime]);

int seconds = lengthSlider.value,minutes = seconds/60,hours = minutes/60;

int secondsRemain = lengthSlider.maximumValue - seconds,minutesRemain = secondsRemain/60,hoursRemain = minutesRemain/60;

seconds = seconds-minutes*60;

minutes = minutes-hours*60;

secondsRemain = secondsRemain - minutesRemain*60;

minutesRemain = minutesRemain - hoursRemain*60;

NSString *hourStr,*minuteStr,*secondStr,*hourStrRemain,*minuteStrRemain,*secondStrRemain;

hourStr = hours > 9 ? [NSString stringWithFormat:@"%d",hours] : [NSString stringWithFormat:@"0%d",hours];

minuteStr = minutes > 9 ? [NSString stringWithFormat:@"%d",minutes] : [NSString stringWithFormat:@"0%d",minutes];

secondStr = seconds > 9 ? [NSString stringWithFormat:@"%d",seconds] : [NSString stringWithFormat:@"0%d",seconds];

hourStrRemain = hoursRemain > 9 ? [NSString stringWithFormat:@"%d",hoursRemain] : [NSString stringWithFormat:@"0%d",hoursRemain];

minuteStrRemain = minutesRemain > 9 ? [NSString stringWithFormat:@"%d",minutesRemain] : [NSString stringWithFormat:@"0%d",minutesRemain];

secondStrRemain = secondsRemain > 9 ? [NSString stringWithFormat:@"%d",secondsRemain] : [NSString stringWithFormat:@"0%d",secondsRemain];

timePlayed.text = [NSString stringWithFormat:@"%@:%@:%@",hourStr,minuteStr,secondStr];

timeRemain.text = [NSString stringWithFormat:@"-%@:%@:%@",hourStrRemain,minuteStrRemain,secondStrRemain];

And import CoreMedia framework

lengthSlider is UISlider
