Hi All,
I'm writing a Lion-only application and trying to do things more iOS-like (which appears to be the direction but regardless, I like it) by creating properties for my IBOutlets. I am using the latest Xcode 4.2 and ARC.
With Xcode 4, I can drag from a control to the header and Xcode will create an outlet and a property. I noticed that Xcode creates a property like this
@property (strong) IBOutlet NSTextField *someField;
But I have other code where it is defined weak -- I started this project on an earlier build of Xcode . The strong and weak are new ARC types replacing retain and assign (if I remember correctly) and I thought that NSWindowController and NSViewController retain their top level objects so in 10.6 if I wanted to do this, I would make the property "assign". Should I be using "strong" as Xcode seems to think now or "weak" as Xcode used to think?
Any advice on this is appreciated.
Thanks
Marc
