Objective C: UISlider (Curve)

Question

Is it possible to have a curve UISlider or is it just Horizontal and Vertical?

I've tried replacing the slider track with a curve image (though i already know hat it will not work because it is just a background), not working.

Is there a way that i could do that?

What exactly do you mean by curve? A quadratic curve? Bezier curve? Circular curve? — Richard J. Ross III, Mar 02 '12 at 07:47
Are you trying to create a circular slider (like the volume control on an old stereo)? — David Rönnqvist, Mar 02 '12 at 08:11

I wrote this sample app to show how to use a Curve UIBezierPath and move an object through it you can take a look at :

I will try to update it.

Take a look at custom controls (both of them are under MIT license):

You can also check out BezierSlider which allows you to customize the path and the selector.

No you can't do this with the UISlider, only in a straight line. You can rotate the whole slider to a degree you like with the transform property and use a function like CGAffineTransformMakeRotation. An example: How to use CGAffineTransformMakeRotation?.
