bigger UISlider ok but tracking zone problem

My goal is to create a bigger UISlider with 35 pixels height for the thumb image.

I subclassed UISlider and added the method :

- (CGRect)trackRectForBounds:(CGRect)bounds
{
    return CGRectMake(bounds.origin.x, bounds.origin.y, self.bounds.size.width, 50);
}

Then I set the thum image from my controller using setThumbImage:

My bigger thumb is well displayed.

The problem I have is that the tracking zone is still the same around 19 px height, how to extend it to 50 ?

Thanks

T.

Solution

  • I believe that you may want to look at thumbRectForBounds:trackRect:value:
