如何在iphone中的Button中使用UIEdgeInsets属性

import UIKit

class CustomButton: UIButton {
    var contentEdgeInsets: UIEdgeInsets = .zero

    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
        let rect = bounds.inset(by: contentEdgeInsets)
        return rect.contains(point)
    }

    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        let rect = bounds.inset(by: contentEdgeInsets)
        return rect.contains(point) ? self : nil
    }
}

let button = CustomButton(type: .system)
button.setTitle("Click Me", for: .normal)
button.frame = CGRect(x: 0, y: 0, width: 100, height: 50)
button.contentEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
button.addTarget(self, action: #selector(buttonClicked), for: .touchUpInside)

@objc func buttonClicked() {
    print("Button clicked!")
}
