将值绑定到数组的第 n 个对象
我有一个 NSView 和一个 NSArrayController，我想将该视图内的一些值绑定到数组控制器的arrangedObjects 数组中的对象。我该怎么做？我考虑过创建一个像“currentObject”这样的属性并将所有内容绑定到它。但这对我来说似乎很丑陋..
（我对所有对象只有一个视图，但用户应该能够单击下一个和后退。）
I have an NSView and an NSArrayController and I'd like to bind some values inside that view to an object in the array controller's arrangedObjects array. How would I do this? I thought about creating a property like "currentObject" and bind everything to that. But this seems ugly to me..
(I only have one view for all the objects but the user should be able to click on next and backward.)

你真正想实现什么目标？通常，“详细视图”绑定到数组控制器的选择，而不是给定索引处的对象。如果您始终连接到同一个对象，只需使用 NSObjectController，将其内容对象设置为所需的对象，然后将您的视图绑定到它。
What are you really trying to accomplish? Normally a "detail view" is bound to the array controller's selection, not an object at a given index. If you'll always be wired to the same object, just use an NSObjectController, set its content object to the desired one and bind your view to it instead.
