R – Showing duration of a song in uilabel or uitextfield

avaudioplayeriphone

I am developing a music player application. I have picked music files from the ipod library, and is playing them. I'm using AVAudioPlayer for this. What i need now is to show the duration of the song on the top of the view. I got the duration as

NSTimeInterval *duration = [musicplayer duration];

But i dont know how to use it to display on the view, on uilabel or uitextfield. Or even using any other value.
Pls help..

Assuming label is your UILabel, try this:

label.text = [NSString stringWithFormat:@"%lf", duration];

Or, if you want it in minute:seconds

label.text = [NSString stringWithFormat:@"%d:%d", (int) (x / 60), ((int) x % 60)]

String formatting is your friend here.

Iphone – fast forwarding a song using AVAudioPlayer

Use the currentTime and duration properties.

i.e. to skip forward

NSTimeInterval time = avPlayer.currentTime;
time += 5.0; // forward 5 secs
if (time > avPLayer.duration)
{
    // stop, track skip or whatever you want
}
else
    avPLayer.currentTime = time;

Similar for going backwards, only compare currentTime against 0, instead of duration

I would refer you to another great forum. It's not as easy as you think by the way. I suggest you start learning how to develop for the iPhone from the start. Just bite the bullet and start!

Here's a link, read it and learn something:

I suggest reading about NSTimer and UIActivityIndicator. Have a nice day, ~ Natanavra.
