Folks;
I have a feeling that this is an embarrassing one so try and go easy on me…
XC 3.2.2
I have a main nib that opens a window and that works fine.
I used to have an NSPanel in this nib to handle preferences.
I've decided it's a good idea to split the nib into two different nibs: the
main nib and a preferences nib.
I've looked over the Sketch project and used it as a model.
I've also read over the Document-Based App Overview FAQ
I've added a window nib to the project and then subclassed a NSWindowController.
I've made the xib's files owner this window controller
At this point I can get a simple empty window to open just fine.
However, I'm using CoreData and I want to pass the existing MOC to the pref
window:
I have added an array controller to the pref nib with its MOC set to files
owner's MOC in IB.
The controller manages an entity not a mutable dictionary.
MOC is a synthesized property of the PrefController (the windowController
mentioned above).
if (!prefPanelController) {
prefPanelController = [[PreferencesController alloc]
initWithWindowNibName:@"testPref"];
[prefPanelController setManagedObjectContext:[self
managedObjectContext]];
}
[prefPanelController showWindow:sender];
No window opens and I get a console error: Cannot perform operation without a
managed object context
Could someone give me the gentle head slap I need here?
Steve
