Question

I have some code for showing a window…

- (IBAction)displayWindow:(id)sender
{
    NSWindow *window = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 50, 50) styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered defer:NO];
    [window setBackgroundColor:[NSColor blackColor]];
    [window setAlphaValue:.5];
    [window setLevel:kShadyWindowLevel];
    [window setReleasedWhenClosed:YES];
    [window makeKeyAndOrderFront:self];
    self.window = window;
}

And to close window….

- (IBAction)closeWindow:(id)sender
{
    [self.window close];
}

and window is defined as a strong property…

@property (strong) NSWindow *window;

The code works the first time but when showing the window a second time the line…

self.window = window;

crashes with EXC_BAD_ACCESS…

what am i doing wrong?

Thanks in advance….

Answer 1

You set “releasedWhenClosed to YES in your code. Change that to NO, and it should work fine.
