Question

I have found that the NSNibLoading methods in NSBundle:

+[NSBundle loadNibFile:externalNameTable:withZone:]
+[NSBundle loadNibNamed:owner:]
-[NSBundle loadNibFile:externalNameTable:withZone:]

have all been marked deprecated in 10.8 – what is the proper way to load the nibs in 10.8 and later?

I’m trying to create a custom sheet in my app, do I have to create NSWindowController with initWithWindowNibName for the custom sheet?

Answer 1

The NSBundle class method loadNibNamed:owner: is deprecated in OS X v10.8,
loadNibNamed:owner:topLevelObjects: is not and the comments in the documentation state why:

Unlike legacy methods, the objects adhere to the standard cocoa memory management rules; it is necessary to keep a strong reference to them by using IBOutlets or holding a reference to the array to prevent the nib contents from being deallocated.
