How to set UiScrollView Frame when clicking UIButton in Iphone?

I have a UIScrollView on which I use 2 UIButtons. The start frame of the UIScrollView (0.0768.1024). I want the UIScrollView y-cordinate position to be 500 by clicking on the first button, which means that it will close 500 positions below its actual position.

And when I press the second button that will be displayed in the UIScrollView, position the Y-cordinate UIScrollView y = 535, the UIScrollView will again move to the y = 0 position.

First, click the UIScrollView y = 500 button. The second button is UIScrollView y = 0

Any tips from experts would be very welcome.
