Swift将检测UISlider图像点击

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let slider = UISlider(frame: CGRect(x: 50, y: 100, width: 200, height: 20))
        slider.minimumValue = 0
        slider.maximumValue = 100
        slider.addTarget(self, action: #selector(sliderTapped(_:)), for: .touchUpInside)
        
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(sliderTapped(_:)))
        slider.addGestureRecognizer(tapGesture)
        
        view.addSubview(slider)
    }
    
    @objc func sliderTapped(_ gesture: UITapGestureRecognizer) {
        let slider = gesture.view as! UISlider
        let point = gesture.location(in: slider)
        
        if slider.bounds.contains(point) {
            print("Slider image clicked")
        }
    }
}
