Accepted answer
Much simpler:

The easiest way is simply setting the Thumb Tint 2 colour to Clear on the Interface Builder - like 1 so...
Voila!
This is an old thread but I found it so 4 someone else may as well.
Here's a solution 3 to this in Swift. I'm creating a blank UIImage 2 here programatically and then assigning 1 it to the thumb.
let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
UIGraphicsBeginImageContextWithOptions(CGSize(width: 1, height: 1), false, 0)
UIColor.clear.setFill()
UIRectFill(rect)
if let blankImg = UIGraphicsGetImageFromCurrentImageContext() {
slider.setThumbImage(blankImg, for: .normal)
}
UIGraphicsEndImageContext()
One line solution:
[_slider setThumbImage:[UIImage new] forState:UIControlStateNormal];

I'd try subclassing UISlider and override -thumbRectForBounds:trackRect:value: to return 2 NSZeroRect. If that doesn't do it, try 1 overriding -thumbImageForState: to return nil.
