Overriding internal UIViewController methods because an internal method is giving me bugs

Question

What are the consequences of overriding internal UIViewController methods?

[UIViewController viewDidMoveToWindow:shouldAppearOrDisappear:] is giving me some problems. It resizes my frame to values I do not desire sometimes. I do not even know where it picks off the new frame's values (it is close to the size of the superview to where I am adding it, but is off by 2px). Reference: this question, which I also need some help with.

I tried defining an empty - (void)viewDidMoveToWindow:(UIWindow *)window shouldAppearOrDisappear:(BOOL)flag method in my view controller. Bug is gone. >.<

Does anyone know if overriding -viewDidMoveToWindow:shouldAppearOrDisappear: is ok to do? Or some other workaround?

Or, does anyone know when and why -viewDidMoveToWindow:shouldAppearOrDisappear: likes to change my frame dimensions sometimes?

Thanks in advance.

If you override that method you run the risk of getting rejected, it is undocumented. An approach that isn't against the rules is to override the setFrame: method of the view in the view controller though.

If you believe this is a bug, put together a minimal test case and submit it to http://bugreport.apple.com and potentially upload it somewhere that we can see exactly what is happening as well.
