如果不使用 NSViewController 来兼容 10.4，你会怎么做？
我需要做的就是在窗口的 NSView 中加载和交换一些笔尖。我知道如何使用 NSViewController 做到这一点，并让它在 10.5-10.6 中完美工作，但我不知道在 10.4 中该怎么做。
非常欢迎教程链接，我很难找到遗留的东西。
（是的，我确实需要支持 10.4。）
All I need to do is load and swap some nibs in a NSView of a window. I know how to do it with NSViewController and have it working perfectly with 10.5-10.6, but I don't know what to do for 10.4.
Tutorial links very welcome, I have trouble finding legacy stuff.
(Yes, I really do need to support 10.4.)

通过在 Leopard 中使用
NSViewController，我可以告诉您它的功能非常基本，您应该能够以相当小的努力来复制它。本质上，它有一个
view属性/出口和一个initWithNibName:bundle:方法。除此之外，它并没有做任何特别花哨的事情。它有一些方便的东西，比如采用NSEditor和representedObject属性。您应该能够在一两个小时内完成同等的课程。现在，如果您这样做，您将放弃与更高版本的 Cocoa 的兼容性。最终，您可能会放弃 10.4 支持，而您将只剩下您的类和真正的
NSViewController。当发生这种情况时，我建议将您的自定义视图控制器重新建立在 Cocoa 的 NSViewController 上。如果您使用与 NSViewController 相同的名称/数据类型来命名属性，则只需删除您自己声明的属性和方法即可。From working with
NSViewControllerin Leopard, I can tell you that its functionality is very basic, and that you should be able to replicate it with fairly minimal effort.Essentially, it has a
viewproperty/outlet, and aninitWithNibName:bundle:method. Beyond that, it doesn't do anything especially fancy. It has some convenience things, like adoptingNSEditor, and arepresentedObjectproperty. You should be able to bang out an equivalent class in an hour or two.Now, what you will give up if you do this is compatibility with later versions of Cocoa. Eventually, you'll probably drop 10.4 support and you'll be left with your class and the real
NSViewController. When that happens, I'd recommend re-basing your custom view controller on Cocoa'sNSViewController. If you've named the properties with the same names/data types asNSViewController, you should only have to drop the properties and methods you've declared yourself.使用
NSBundle加载笔尖：Use
NSBundleto load the nib:基本上，您编写自己的控制器类，它执行与 NSViewController 相同的操作。控制器类被添加到 AppKit 中，因为我们很多人一遍又一遍地编写本质上相同的代码。
Basically, you write your own controller class that does the same things that NSViewController does. The controller classes were added to the AppKit because so many of us were writing essentially the same code over and over.
