如何在swift 4.2中防止意外触摸触发touchesBegan？

class CustomView: UIView {
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        guard let touch = touches.first else { return }
        let touchLocation = touch.location(in: self)
        
        // Add condition to filter out accidental touches
        if touchLocation.x > 100 && touchLocation.y > 100 {
            // Handle the touch event
            super.touchesBegan(touches, with: event)
        }
    }
}

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
        view.addGestureRecognizer(tapGesture)
    }
    
    @objc func handleTap(_ gesture: UITapGestureRecognizer) {
        let touchLocation = gesture.location(in: self.view)
        
        // Add condition to filter out accidental touches
        if touchLocation.x > 100 && touchLocation.y > 100 {
            // Handle the tap event
        }
    }
}
