objective-c - 不带 Nib 的 NSRecentDocumentsMenu 的沙箱友好安装

Question

我正在开发一个(当前)根本不使用任何 nib 文件的项目。

我试图弄清楚是否有任何方法可以添加不需要使用私有(private) API 的 NSRecentDocumentsMenu 打开最近菜单。

以下链接是我迄今为止找到的所有链接: http://lapcatsoftware.com/blog/2007/07/10/working-without-a-nib-part-5-open-recent-menu/

有人可以提供见解吗？

Answer 1

I'm trying to figure out whether there is any way to add the NSRecentDocumentsMenu Open Recent menu that doesn't require use of a private API.

以下链接适用于 swift 中基于文档的应用程序，不使用 nib:

它使用此引用中找到的菜单代码的修改:

https://talk.objc.io/episodes/S01E145-setting-up-a-document-based-app

该演示可以通过使用 swift 和 XIB 接口(interface)创建 macOS 应用程序在 Xcode 中运行，尽管我们不会使用 XIB。创建一个名为 main.swift 的新文件并删除现有的 AppDelegate 类。将上面找到的源代码复制/粘贴到 main.swift 文件中(使用 import Cocoa 而不是 Foundation)。当您点击“运行”按钮时，您会注意到菜单呈灰色，并且没有“打开最近的”菜单项。要解决此问题，请务必将 Cocoa NSDocument 类和角色添加到 info.plist(请参见上面文件夹中的图像)。 Cocoa NSDocument 类应该是 swift 的 nameOfYourApp.Document 或 objc 的普通文档。当添加这些内容后点击“运行”按钮时，您应该有一个基于文档的应用程序，其中包含一个功能正常的“打开最近的”菜单项。如有问题请留言跟进。

Objc源代码在这里:

说明与 swift 的说明类似，但 macOS 应用程序是使用 Objective-C 创建的。删除 Xcode 提供的内容后，将源代码复制/粘贴到 main.m 中。为了简单起见，还删除 AppDelegate 和 Document 类(如果您在设置中选中了“基于文档”)，尽管您可以根据需要使用它们。 info.plist 也必须根据上面提到的两项内容进行修改。
