Reference outlet to main NSWindow in AppDelegate (OSX)

Question

When you create a new project, I seem to remember you being able to access the basic blank window it creates in the storyboard using self.window in the AppDelegate methods.

I can't seem to set a reference outlet to the AppDelegate.h file via the storyboard either. Am I just hallucinating or is there no way to access the window/controller from AppDelegate ?

Am I mixing up iOS and OSX practices?

Answer 1

Using storyboards, it seems impossible to connect the WindowController to AppDelegate. I used the following to get a reference to the main window:

AppDelegate.h

@property (weak) NSWindow* window;

AppDelegate.m

    - (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
            _window = [[[NSApplication sharedApplication] windows] firstObject];
    }

See this question for swift solution. Hope this helps :)

Answer 2

It's working for me.

I added an IBOutlet to my AppDelegate.h

@property (nonatomic) IBOutlet NSWindow *window;

Then in your Interface Builder (MainMenu.xib for me) select App Delegate:

Your IBOutlet should be in the Connection inspector to the right:

Maybe the connection between your .xib and your AppDelegate is lost?
