How to customize MPVolumeView?

Question

I have tried many methods to implement a regular UISlider and control the device volume, but it\'s all Native-C functions which results in many untraceable bugs.

Answer 1

Answer in Swift:

func customSlider() {
        let temp = mpVolView.subviews
        for current in temp {
            if current.isKind(of: UISlider.self) {
                let tempSlider = current as! UISlider
                tempSlider.minimumTrackTintColor = .yellow
                tempSlider.maximumTrackTintColor = .blue
            }
        }
    }

Result:
