You need to customize <code>UISlider</code>. You can do it like this:

<pre><code>[slider setMinimumTrackImage:[[UIImage imageNamed:@"redSlider.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];
</code></pre>

Result:

Here is some backgrounds for sliders and example image how they looks:

After you alloc

<pre><code>volumeView = [[MPVolumeView alloc] initWithFrame:CGRectMake(40, 145, 270, 23)];
</code></pre>

Just search the MPVolumeView subviews and get the slider

<pre><code>for (id current in volumeView.subviews) {
 if ([current isKindOfClass:[UISlider class]]) {
 UISlider *volumeSlider = (UISlider *)current; 
 volumeSlider.minimumTrackTintColor = [UIColor redColor];
 volumeSlider.maximumTrackTintColor = [UIColor lightGrayColor];
}
</code></pre>

Put the colors you like in UIColor and all done.
If you need to customize further, treat volumeSlider as a standard UISlider.

How can I change the tintcolor of the slider in a MPVolumeView? Instead of blue I want to display a different color.
