如何获取在xib文件中创建的NSWindow的引用？ [英] How can get a reference to an NSWindow created in a xib file?

问题描述

我使用xib文件显示名为mainWindow的 NSWindow - 现在我想通过代码获取对mainWindow的引用（例如 NSWindow * mainWindow ）。我在文档中找不到任何内容，任何指针？

I use a xib file to show an NSWindow named mainWindow - now I want to get a reference to mainWindow via code (e.g. NSWindow *mainWindow). I can't find anything in the documentation, any pointers?

推荐答案

xib文件中会有app占位符对象委托和/或文件的所有者。

The xib file will have placeholder objects in it for the app delegate and / or the file's owner.

假设其中包含app委托，您可以获取对窗口或xib中任何对象的引用

On the assumption that it has the app delegate in it, you can get a reference to the window or any object in the xib by

1. 在正确类型的app委托中声明属性，并将IBOutlet作为其类型的一部分：

1. Declare a property in the app delegate of the right type and with IBOutlet as part of its type:

@property (weak) IBOutlet NSWindow* theWindow;

在xib中找到app delegate对象。按住控制键时单击并拖动它。你应该在鼠标指针和对象之间找到一条线。

Locate the app delegate object in the xib. Click and drag it while the control key is pressed. You should get a line between the mouse pointer and the object.
