I need to programatically remove a button from a window in Cocoa but the only method close to this was dealloc in NSObject, but this is not what I want to do. Is there a way to actually delete the button from the window not just deallocate its memory?

A:
Send the removeFromSuperview message to the button instance.
Though perhaps you just want to hide it instead (using setHidden:)?

Worth pointing out that views retain their subviews, which means that removing the button from its superview will cause the superview to release it, possibly resulting in it deallocking. I agree that hiding the button is probably more useful.

A:
An NSButton is a subclass of NSControl, which itself is a subclass of NSView.
You should be able to remove the button from it's superview by calling -removeFromSuperView on the button instance.
