NSWindowController's window released immediately

Question

I\'m trying to open a window using a NSWindowController in my app delegate. I created a basic NSWindowController with an associated NIB and try to show the window that way:<

Answer 1

You need to add a property to your app delegate (or some other object that's going to stick around for the lifetime of your app) that retains theWindowConroller. For example:

@interface MyAppDelegate : NSObject

@property (strong, nonatomic) MyWindowController * windowController;

@end

Then set this property when you initialize the window controller.

@implementation MyAppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Show the main window from a separate nib
    self.windowController = [[MyWindowController alloc] initWithWindowNibName:@"MyWindowController"];
    [theWindowController showWindow:self];
}

@end
