UISlider setMaximumTrackTintColor

Question

I\'m trying to dynamically configure the track color on a UISlider.

This line of code works perfectly for setting the low side of the slider track.

This is an Apple bug, and it still exists in iOS 8. I've seen it when trying to modify the maximum tint color of sliders via an proxy setter on a subclass. Changing the minimum tint color works fine and shows no errors, but trying to change the maximum tint color throws tons of bad context errors and often draws that portion of the slider gradient in the wrong location (which proves it does indeed not have a good context).

I could find no workaround for the problem, but will file a bug report.
