`pushViewController:animated:` with fade animation (animate transition only)?

Question

There a lot of similar questions with answers. For example:

link

but almost all of them are unsuitable because I also want to perform something like this:

button1.frame = button2.frame;
button2.hidden = YES;

So if I use an example with beginAnimations: then I can see how button1 changes its frame (it moves while app perfoms a transition animation).

How to solve this issue? First of all should I set a button frame in another way or should I find another code for transition?

EDITED

Additionally I have found out that not all ways allow to show fade animation I need so I have edited my question a little.

The best solution from it is animating way which works for my case.

The most strange thing is to disable view controller's own animation instead of its changing.
