NSView is not showing up after it was added as a subview (Cocoa/OSX)

In my program I have the following set up:

I have 3 NSViews which I made in the interface builder enter image description here

So PaintView is a subview of PlayerView and ImageView is the view on top of PlayerView.

When the program starts ImageView is hidden. The PaintView is transparent so I see the PlayerView under it but clicking happens on PaintView. So far so good.

Now, what I want to accomplish is that when I press the button, PlayerView becomes hidden, ImageView becomes visible and the PaintView becomes its subview. So I can see the ImageView trough transparent PaintView, but still be able to click on PaintView.

What my approach was so far is something like this:

// on the app start

[ImageView setHidden: YES];

// on the button press
[PaintView removeFromSuperview];
[PlayerView setHidden:YES];
[ImageView setHidden:NO];
[ImageView addSubview:PaintView positioned:NSWindowAbove relativeTo:nil];

Unfortunately, this doesn't give me the desired result. ImageView is on the very top, so I can't click on PaintView.

Does anyone know what am I doing wrong?! Any kind of help is really appreciated!

Thank you!

removeFromSuperview releases that object and everything that it contains. Check to see if PaintView is nil at the point where you're trying to add it to another view.
