Swift:如何创建/定义用户触摸图像的区域(宽x高)？

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let imageView = UIImageView(image: UIImage(named: "image"))
        imageView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
        imageView.isUserInteractionEnabled = true
        view.addSubview(imageView)
        
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
        imageView.addGestureRecognizer(tapGesture)
    }
    
    @objc func handleTap(_ gesture: UITapGestureRecognizer) {
        let touchLocation = gesture.location(in: gesture.view)
        
        let definedRect = CGRect(x: 50, y: 50, width: 100, height: 100)
        
        if definedRect.contains(touchLocation) {
            print("用户触摸在定义的区域内")
        } else {
            print("用户触摸不在定义的区域内")
        }
    }
}
