Hello,
I'm encountering some weird behavior when trying to update a view using
windowControllerDidLoadNib after loading in a persistent document.
When I provide windowControllerDidLoadNib a single argument, as shown below
(and required by the NSDocument class definition and in every example I've
seen),
Xcode says: `windowControllerDidLoadNib:': wrong number of arguments (1 for
0) (ArgumentError)
If I don't provide any argument, it says: undefined method
`windowControllerDidLoadNib' for #<MyDocument:0x200646660> (NoMethodError)
*I've tried every combination of one or no args for both the method
signature and "super" call on the next line, and I can't seem to get any
different results.*
This is my first time trying to get persistence going, but I've read a lot
about it, and everything else is working well.. it saves and loads, but I
can't seem to get this hook
working to update the GUI upon loading.
*

*
*
class MyDocument < NSDocument
attr_accessor :loadedmodel, :root #outlet to model field of controller
# Name of nib containing document window
def windowNibName
'MyDocument'
end
# Document data representation for saving (return NSData)
def dataOfType(type, error:outError)
outError.assign(NSError.errorWithDomain(NSOSStatusErrorDomain, code:-4,
userInfo:nil))
NSKeyedArchiver.archivedDataWithRootObject(@root.model)
end
# Read document from data (return non-nil on success)
def readFromData(data, ofType:type, error:outError)
outError.assign(NSError.errorWithDomain(NSOSStatusErrorDomain, code:-4,
userInfo:nil))
@loadedmodel = NSKeyedUnarchiver.unarchiveObjectWithData(data)
end
# Return lowercase 'untitled', to comply with HIG
def displayName
fileURL ? super : super.sub(/^[[:upper:]]/) {|s| s.downcase}
end
def windowControllerDidLoadNib(aController)
super(aController)
@root.model = @loadedmodel
NSLog("model loaded")
end
end
Regards,
Tom Jordan
