each page contains a collection view. in collection view, i have to show information which contains images and text from server. and it will have at most 500 contents.

Suppose there are some pages in page view controller.
and large title is enabled.
Each page has tableview.
let's say, one page's navigation bar is collapsed and just before or after page navigation bar is being shown large title.
if I swipe left or right, the large title is jumped off the navigation bar.

Sometimes I am getting Black screen during fast swipe of pageViewController.
in iPhone home screen, if I want to fast swipe, system somehow slows it down.
And Apple also used page view controller in home screen.
To overcome black screen , I want to slow page view controller swipe. But I could not find any delegate method to resolve this.
So my query is two:
How to resolve black screen appearance during fast swipe of page view controller?.
if I want to make page swipe to slow, how to do it just like Apple did in their iPhone/iPad home screen?

I have a PageViewController with PageControl. if I tap on pageControl too fast, sometimes it happens that, two pages are being shown as half.
That is, One page is being shown as a small portion and the other page is being shown as rest of the portion.
This issue happens only when I tap on pageControl too fast.
How to resolve this issue?
Please note that, in iPhone application menu/Home screen, they also used PageViewController. But during fast tap of pageControl, they somehow slowed down the swiping of pages .

I have setup a "UIViewController" (Embedded in "UINavigationController"), and the "UIViewController" has a "ContainerView" with a "UIPageViewController".
In the "UIPageViewController" are few subviews with "UITableViews".
The problem is now, the "UINavigationBar" with enabled "Prefer Large Titles" are not collapsing if the TableView (Embedded in ContainerView) scrolls.
I think that's a problem with the "UIPageViewController". The size is the same as the ContainerView.
How can i fix this issue ?
