只需在 Cocoa 中制作一个标签说“Hello World”（Mac 编程）
我是 Mac 上可可编程的新手，所以这个问题可能很简单。我有一个窗口，在那个窗口上有一个标签。
我希望能够从我的程序中更新此标签的当前状态或正在发生的事情（例如，读取文件、解析等）。我的问题是我不知道如何访问标签并更改其文本属性。我尝试了“MyWindowName”。希望我能够从窗口引用标签。我什至不知道标签的名称是什么，甚至不知道它是否有名称。
如何在我的程序中引用此标签来更改它？
I'm a total newbie to programming in cocoa for the mac so this question is probably easy. I have a window, and on that window I have a Label.
I want to be able to update this label from my program with the current status or what's going on (eg. reading in file, parsing, etc.). My problem is that I don't know how to access the label and change it's text property. I tried "MyWindowName." hoping I would be able to reference the label from the Window. I don't even know what the labels name is, or even if it has a name.
How do I reference this label in my program to change it?

您可能需要转到此处并浏览一些教程：http://www.cocoadevcentral.com/
快速总结是，与其他技术不同，您不直接访问控件（或不应访问它们）。相反，您可以在控制器中创建插座，然后以图形方式连接到控件，它们会自动更新。这些教程将为您指明方向。
You probably need to go here and walk through some tutorials: http://www.cocoadevcentral.com/
A quick summary is that unlike other technologies, you don't access the controls directly (or shouldn't access them). Instead, you create outlets in a controller, which you then graphically connect to the controls and they update automagically. These tutorials will show you the way.
标签只是一个
NSTextField，具有有关编辑/字体等的不同设置。只需在控制器中创建一个连接到 Interface Builder 中视图的插座，然后您就可以像更改任何其他 <代码> NSTextField 。A label is just an
NSTextFieldwith different settings about editing/fonts, etc. Just make an outlet in your controller that connects to the view in Interface Builder, and you can change it like you would any otherNSTextField.
