Swift 海关；关于申请”；Mac Catalyst窗口

是否更改Mac Catalyst的“关于应用程序”窗口？ 这是怎么做的？

类似这样的事情：

#if targetEnvironment(macCatalyst)
extension AppDelegate {
override func buildMenu(with builder: UIMenuBuilder) {
    guard builder.system == .main else { return }

    // override about button
    builder.replaceChildren(ofMenu: .about) { (oldChildren) -> [UIMenuElement] in
        let menuElement = oldChildren.first
        if let uiCommand = menuElement as? UICommand {
            let aboutUICommand = UICommand(title: uiCommand.title,
            action: #selector(aboutApp(_:)))
            return [aboutUICommand]
        } else {
            return oldChildren
        }
    }
}

override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        return super.canPerformAction(action, withSender: sender)
}

override func target(forAction action: Selector, withSender sender: Any?) -> Any? {
    if action == #selector(aboutApp) {
        return self
    } else {
        return nil
    }
}

@objc func aboutApp(_ selector: Any?) {
    guard let aboutTVC = AboutViewController.createInstance() else { return; }
    rootViewController?.present(aboutTVC, animated: true, completion: nil)
} 
} 
#endif

非常感谢！我成功地将About菜单项链接到一个模态视图。是否也可以将About视图作为一个单独的窗口（“应用程序窗口外”）获取？标准的“关于窗口”与“应用程序”菜单是分开的。是的，但您需要为应用程序启用多窗口，并使用uiscenedelegate来管理窗口
