iOS16适配：UIEditMenuInteraction的使用

UIEditMenuInteraction是iOS16中新增的菜单交互类，用于取代UIMenuController 与 UIMenuItem。目前 UITextField与 UITextView 已经默认支持UIEditMenuInteraction

• 下面的代码主要是在UITextField中的使用

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

    lazy var textField: UITextField = {
        let _textField = UITextField(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width - 40.0, height: 44.0))
        _textField.borderStyle = .roundedRect
        _textField.delegate = self
        _textField.center = self.view.center
        _textField.text = "UIEditMenuInteraction"
        return _textField
    }()
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.addSubview(self.textField)
    }
    // MARK: 通过代理方法添加交互的菜单
    func textField(_ textField: UITextField, editMenuForCharactersIn range: NSRange, suggestedActions: [UIMenuElement]) -> UIMenu? {
        let _copy = UIAction(title: "复制") { _ in
            print("复制内容")
        }
        let _favorite = UIAction(title: "喜欢") { _ in
            print("喜欢收藏")
        }
        let _share = UIAction(title: "分享") { _ in
            print("分享")
        }
        let _delete = UIAction(title: "删除", attributes: [.keepsMenuPresented]) { _ in
            print("删除")
        }
        let _menu = UIMenu(title: "测试", preferredElementSize: .small, children: [_copy,_favorite,_share,_delete])
    
        return _menu
    }
}
