The following will work fine for the first language:

"WANTS" = "%@ wants a %@";

For the second language, you would need to explicitly indicate the index of the token you want to insert. This is done with a number and the dollar sign:

"WANTS = "A %2$@ is what %1$@ wants".

Chapter 17. Custom Views

All visible objects in an application are either windows or views. In this chapter, you will create a subclass of NSView. From time to time, you may need to create a custom view to do custom drawing or event handling. Even if you do not plan to do custom drawing or event handling, you will learn a lot about how Cocoa works by learning how to create a new view class.
