backBarButtonItem with popViewController and swipe - objective-c

Question

My App logic is like that: VCA => VCB, and there is a scroll view in VCB with swipe left and right function. Some code help to understand structure, in VCB:
self.scrollView.pagingEnabled = YES;
self.scrollView.directionalLockEnabled = YES;
self.scrollView.contentSize =CGSizeMake(CGRectGetWidth(self.scrollView.frame) * numberPages, CGRectGetHeight(self.scrollView.frame));
so what I want is list some pages horizontally and swipe to left and right to navigate. Each page has it own view controller(child view controller of VCB) and I add them like that:
if (controller.view.superview == nil)
{
[self addChildViewController:controller];
[self.scrollView addSubview:controller.view];
[controller didMoveToParentViewController:self];
}
So far it works fine for iOS 6. I can swipe to change page. All function inside each page also works fine.
Then the problem comes with iOS 7's new feature, swipe to right to automatically call popViewControllerAnimated:, same effect like click go back button. To solve the conflict, I disable the interactivePopGestureRecognizer: self.navigationController.interactivePopGestureRecognizer.enabled = NO;
and it works ok, no force to pop back when I just want to swipe change the page.
Now the real problem. I set a back button(backBarButtonItem) on navigation bar. Every time I use that button pop from VCB back to VCA and current page is not the first page (that means there is at least one page on the left side), the pop animation is like first change page to the left side one, then immediately show VCA without any animation.
So any solution? Please help me.

Answer 1

First of all, it is hard to determine the problem without any piece of your code.
And secondly, why won't you create the button yourself, and add a target to it, a function that'll dismiss / pop the view controller?
