UIPageViewController' s Child View Controller has wrong lifecycle

When i close to UiPageVC, after UiPageVC's viewWillDisappear call, ChildVC's viewWillAppear and viewDidAppear function calls. At the end, UiPageVC's viewDidDisappear works.

I need to work ChildVC like normal way. When i dismiss to UiPageVC, viewWillDisappear and viewDidDisappear of ChildVC should call.
Exactly same problem (feature?) here
