根据状态在UIButton中更改ImageView的色调颜色

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var button: UIButton!
    @IBOutlet weak var imageView: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
    }
    
    @objc func buttonTapped() {
        if button.isSelected {
            imageView.setImageTintColor(.red)
        } else {
            imageView.setImageTintColor(.green)
        }
        
        button.isSelected = !button.isSelected
    }
}
