I'm using a UISlider
in my app but I'd like to use a custom "look-and-feel" for it. I have changed the thumb to my own image but is there a way to change the bar also? I have a bar image I would like to use but can't see how to do this.
I have found how to change the max and min image but not the bar itself.
You were right to use -setMinimumTrackImage:forState:
and -setMaximumTrackImage:forState:
methods. What you missed is that you should provide stretchable UIImage
to them, the rest is taken care of automagically:
UIImage *sliderLeftTrackImage = [[UIImage imageNamed: @"SliderMin.png"] stretchableImageWithLeftCapWidth: 9 topCapHeight: 0]; UIImage *sliderRightTrackImage = [[UIImage imageNamed: @"SliderMax.png"] stretchableImageWithLeftCapWidth: 9 topCapHeight: 0]; [mySlider setMinimumTrackImage: sliderLeftTrackImage forState: UIControlStateNormal]; [mySlider setMaximumTrackImage: sliderRightTrackImage forState: UIControlStateNormal];
You can use the same image for both the min and max parts.
