How to customise UISlider height

Question

I have project in which have to customise UISlider element. I wondering if someone knows how to change, or is it possible to change height of UISlide

Answer 1

Overriding trackRect is a way to go, however if you're using additional UISlider's views like minimumValueImage, maximumValueImage you would also need to take their bound into account, otherwise they will overlap with slider’s track. As a shortcut you can simply use super's func:

Fixed version.

Swift 3+

 @IBDesignable
    class CustomSlider: UISlider {
       /// custom slider track height
       @IBInspectable var trackHeight: CGFloat = 3

       override func trackRect(forBounds bounds: CGRect) -> CGRect {
           // Use properly calculated rect
           var newRect = super.trackRect(forBounds: bounds)
           newRect.size.height = trackHeight
           return newRect
       }
}
