How to replace UISlider with UIProgressView playing MPMoviePlayerController?

Question

I am having a hard time trying to replace UISlider on my app playing a invisible MPMoviePlayerController with UIProgressView.

UISlider is just create, very intuitive to change, Pretty much on the Update selector from MPMoviePlayerController I update its current status:

and previously I defined the min and max from the content of the MPMoviePlayerController:

-(void)UpdateTime:(NSTimer*)Timer
{

[self.sldProgress1 setValue:[[NSNumber numberWithDouble:playerSong.currentPlaybackTime] floatValue]];

}

UIProgressView doesn't provide similar approach, and I didn't find on the web a sample that matches what I am trying to do:

        sldProgress2.maximumValue = [playerSong playableDuration];
        sldProgress1.value = 0.0;

any suggestions?

UIProgressView doesn't have the concept of a user-settable max value - it's just 100.0. To make it work as you want, you'll have to do some math. Luckily, it's easy math:

CGFloat percentComplete = [playerSong.currentPlaybackTime floatValue] / [playerSong.playableDuration floatValue];

That will give you the percentage of the song that's complete, and you just update your UIProgressView to that number.

progressView.progress = percentComplete;

More or less - this code was mostly pseudo based on your question, but that's the idea.
