objective-c - cocoa-How to manage individual NSWindow of different nib files and multiple subviews under one NSWindow?

Question

In a project, for different nib files, should each nib have a NSWindow?
Or, only one nib file has a NSWindow, and other nib views are directly added to that window when they need to be displayed?

For a NSWindow, how to manage its multiple subviews?
For example, there are two interfaces. If I add them to the subview of this window, how do I get them?

Answer 1

Prior to OS X 10.9, the best practice regarding NSWindow was an NSWindow .Xib对应一个NSWindowController。所有的子视图全部可以添加到其 contentView.
You can use Tag or property to get the view.
