Customize UISlider color

Instead of having 3 UISlider with 3 UILabels telling red, green, blue, we have 3 UISlider with custom colors. Everybody would agree that this is nicer…

To do this, just customize your UISlider this way :

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

Then you just need the images. Taken (and edited) from the UICatalog Apple Template :
