 with some compromise, and it will require some effort.
On the first look I came up with this strategy:

add some BOOL property, let's call it 'isPresenting' and set it to NO initially.
on sliderValueChange, if isPresenting is NO, start presenting view.
set property 'isPresenting' to YES.
when each of the views finishes presenting itself, set isPresenting to NO. 
check if slider is sliding, if not call changeValueSlider: manually

Note: steps 4. and 5. should be executed from child views (viewDidAppear:), so you should use either protocol or local notification to do that, or have a reference to parent view controller in children and call parent's method from child.

 Q:

Does God continually (re)create the physical world?

1) Does God continually renew the physical world in the sense that if he didn't give direct input at any given moment it would disappear?
2) If the answer to #1 is that God does continually (re)create the physical world, does he do so for the parts of the world that are not being observed by a human?

A:

Does God Continually ReCreate the World?
Yes, most explicitly according to the Shacharit prayers (ברכות ק"ש - המחדש בטובו בכל יום תמיד מעשה בראשית), R' Dessler (מכתב מאליהו חלק א), and the Zohar (חלק ב' קמט), but also according to Ramban (שמות יג:טז, דרשת תורת ה' תמימה), Bavli Chagigah 12b, and Tanya (Shaar Hayichud Vehaemunah).
No, based on extrapolations of the following opinions, all of which assume that the world runs according to "nature," ie. that there is a automatic system that God created during Creation that runs the world: Ramban (דברים יא:יג,  איוב לו:ז, בראשית יח:יט), Rambam (
