I'm having some problems removing a layer...

I use this code:
[self removeChild: pauseLayer cleanup: YES];

The "pauseLayer" is a layer that is a child of another layer. But, when I try to remove the layer(child) it still shows the layer normally. It doesn't get rid of it. Should I not be using removeChild here, but instead, something else?

Please tell me if you need more information, I'll be glad to give it. This is the only thing I'm having trouble doing in my app. So please help, and thanks in advance.

I forgot to tell what I was trying to do...sorry.

I'm trying to just get the pauseLayer to disappear and not take any presses.

[A removeChild:B cleanup:YES];

A must be the parent of B. Try:

[pauseLayer.parent removeChild: pauseLayer cleanup: YES];

As an aside, while Cocoa does it this way too, it is a weird way to handle it. Instead maybe it should just be:

[B removeWithCleanup: YES];

and let the method figure out the parent. I think this is a legacy method from the time when cocosNodes could be the child of multiple parents, so it was required to specify which parent you meant.

[edit] Maybe:
```
-(void) removeWithCleanup:(BOOL)cleanup
{
  if (self.parent == nil)
    return;

  [self.parent removeChild:self cleanup:cleanup]
}
```

ok, instead try pauseLayer.visible=NO; pauseLayer.isTouchEnabled=NO;

Sorry for such a late response, but this didn't work for me.

The pauseLayer.visible=NO; worked perfect, it disappeared from the screen, but the pauseLayer.isTouchEnabled=NO; didn't work at all. It'll still take touches.

I don't get this at all. I've been able to figure out most of my issues within a couple of days, but this is just making absolutely not sense. I thought it'd be simple to completely remove a layer, but it doesn't seem so.

How do I completely delete/remove/get rid of a layer that is a child of another layer? Suggestions or ideas would be greatly helpful.

You can move the entire layer off screen and it won't register touches.

Ya...I guess I could do that, but wouldn't that be a poor way of doing it? Performance wise at least. I wish I could somehow just completely delete/get rid of the layer.

@SamGray: did you try my suggestions here:

If you tell the parent of that Layer to remove it, it still doesnt work?
