slider - iOS Movement of UISlider thumb to track the progress of the movie -

i'm implementing video player in i've taken uislider track progress of movie. mean thumb of slider should @ max value when movie finishes.

i'm not able achieve this. movie finishes before thumb reaches @ end. please me understand issue?

this code i've written:

//i'm setting min, max values of uislider , calculating current value progressbar.minimumvalue = 0.0; progressbar.maximumvalue = (float)movie.duration; progressbar.value = ((float)movie.currentplaybacktime/(float)movie.duration) * progressbar.frame.size.width; 

just use progressbar.value = (float)movie.currentplaybacktime; instead of progressbar.value = ((float)movie.currentplaybacktime/(float)movie.duration) * progressbar.frame.size.width;
