1st time I click on menu item I see the window. I then use close button. Click
on the same menu item and get nothing. Action handler executes, but I see no
window.
In app delegate:
@property (strong, nonatomic) NSWindowController *myWindowController;
- (IBAction)openSingleWindow:(id)sender {
if (self.myWindowController == nil) {
self.myWindowController = [[NSWindowController alloc]
initWithWindowNibName:@"MyWindow"];
}
NSLog(@"window: %@", self.myWindowController.window); // displays nil at
all times
[self.myWindowController showWindow:self];
NSLog(@"window: %@", self.myWindowController.window); // displays nil at
all times
}
window is configured with options:
(unchecked) Release When Closed
Xib file owner is set to NSWindowController
What am I missing?
My goal is to display one window at a time (Preferences). Creating new
controller and displaying it caused multiple windows.
