How to set UISlider's MinimumTrackImage so that it won't strech?

Ever since I've updated my XCode, the MinimumTrackImage on my UISlider is now stretching, when before it was clipping like I wanted it to. The MaximumTrackImage's behavior didn't change.

How can I get the MinimumTrackImage to not stretch? Note that I use rubymotion, but a solution using obj-c is also acceptable.

I'm guessing here (you are allowed to guess on StackOverflow as long as you're honest about it)... There is a new iOS6 feature for images and perhaps that is getting in your way here. You can set the resizingMode and capInsets for an image. Try this:

// Objective-C
UIImage *newImage = [oldImage resizableImageWithCapInsets:UIEdgeInsetsZero resizingMode:UIImageResizingModeTile];

# RubyMotion
newImage = oldImage.resizableImageWithCapInsets(UIEdgeInsetsZero, resizingMode:UIImageResizingModeTile)

If you need to adjust the insets as well, replace UIEdgeInsetsZero with UIEdgeInsetsMake(top, left, bottom, right) where top, left, bottom, and right are floats. In RubyMotion, I believe you can just use [top, left, bottom, right].

Info came from here: http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIImage_Class/Reference/Reference.html
