Customizing UISlider appearance

I want to set the thumb image of a slider for a normal state, but still use the default track images.

So i do this:

[theSlider setThumbImage:[UIImage imageNamed:@"my_thumb.png"] 
forState: UIControlStateNormal];

and I get my image appear as thumb, but then default track images disappear.

Can't you just customize the thumb image and leave the track images default?

When you are creating your UISlider, whether it be in Interface Builder or progmatically be sure to set the Continuous variable to YES. (ie. [mySlider setContinuous:YES]). After this variable is set, you should be able to use your own thumb images.

It doesn't seem like this is possible, strangely.

As a workaround, you have a couple choices. It shouldn't be too difficult to screenshot and extract the necessary graphics to create your own nearly-identical min and max track images. You'll need to get the rounded edges and a couple pixels of the flat part which will be stretched.

Alternately, you could try to extract the actual images using this technique: Extract UIKit artwork

Personally, I don't see why you can't mix and match custom graphics with default graphics, but this seems to be how Apple implemented this control.
