    I'm just playing around with OSX app dev. I'm totally noob.
    I thought it is straight forward like iOS app dev. But after a few days
    of going at this, it seems it is not that easy.

    Here's what I'm trying to do. I have a NSWindow. In it I put an Image Well (wth with the naming? lol)
    Well, it is an NSImageView (no pun intended).

    So I just want the NSImageView frame to resize following the NSWindow size. It's that simple.

    Here's what I did that is NOT working:

    NSImageView as imageView.

    write the delegate method of NSWindow windowDidResize and just resize the framesize
    of imageView in it.
    - (void)windowDidResize:(NSNotification *)notification {
       // NSLog(@"resized");
        NSRect zWindowRect = [[self window]frame];
        NSRect zContentRect = [[self window]contentRectForFrameRect:zWindowRect];
        [self.imageView setFrameSize:NSMakeSize(zContentRect.size.width,
        [self.imageView setNeedsDisplay:YES];
    This delegate is called (tested with that NSLog).
    However the NSImageView just stays there with the original size.
    I checked the IBOutlet connection is ok.

    What gives? Why won't the NSImageView resize?

    What makes you think the view is not resizing? Maybe it is but it's not set to scale it's content...

    Scaling is set to Proportional so that was not the problem.

    I have found out the cause though - "Use Auto Layout" was checked for the NIB file.

    Unchecked that and everything works well now.
    Thanks for replying though. :)
