由于我是新手，所以我在这里浏览一些文档：https://wiki.wxwidgets.org/Creating_Xcode_projects_for_wxWidgets_applications。
我的问题是，minimum_cocoa运行应该是什么样？我的minimal_cocoa无法运行。在xcode中按'run'会立即返回任何内容。
我的环境是
以下是所述的目标内容：
Contents
1 Create the library
2 Compile the basic sample.app
3 In Build Settings
4 Finally
我已经成功执行1）和2），但是当我按2的运行时，什么也没有发生。我已经设置了XCODE断点，但从未达到过。这应该运行正确吗？
你们中的wxWidgets同事之一，请把他们的编译和运行minimum_cocoa结果的屏幕截图显示出来吗？
这里是wxWidgets提供的minimal.cpp

您好wxWidgets / C ++开发人员：我对XCode和wxWidgets都是陌生的，我想知道minimal_cocoa应该是什么样？我正在使用截至昨天的最新wxWidgets。我做了一个git clone / ...
samples/minimal/minimal_cocoa.xcodeproj，该树在运行时应显示一个空窗口（不称其为“最小”）。
