How to change the tintcolor of the slider in a MPVolumeView?

Question

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

Answer 1

You need to customize UISlider. You can do it like this:

[slider setMinimumTrackImage:[[UIImage imageNamed:@"redSlider.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];

Result:

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

Answer 2

After you alloc

volumeView = [[MPVolumeView alloc] initWithFrame:CGRectMake(40, 145, 270, 23)];

Just search the MPVolumeView subviews and get the slider

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

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