UISlider track image that doesn't stretch

Question

Hi All,

I'm trying to use a custom track image for a UISlider but it is an asymmetric image from one end of the slider to the other.

I have tried setting up my image with leftCapWidth and so on but this just makes it take a maximum stretch and then starts spreading out one pixel of infor across the slider.

I'd like an image that doesn't change at all when you move the slider.

Is this at all possible?

Thanks!
