UIPageControl problems, Objective-C

I have been working on implementing UIPageViewController for some time now. I have went through many problems that i managed to solve by myself and with some extra help. Now i am stuck with the last part and that is the UIPageControl.

I got two problems that i would like some help with:

Problem 1: Is there any simple way to resize the dots for the pageControl?

Problem 2: This is how it is built:

I know it is hard to see but i will explain them starting from the upper left corner and going to right. First VC is simply a Navigation Controller pointing to a UITableViewController.

in the second row the first VC is the datasource delegate for the UIPageVIewController. The one next to it is the PageViewController, The two UITableView's next to it is the "pages" that are in the UIPageViewController. And the last one is the PageContentViewController.

So i added this code in viewDidLoad to the datasource VC meaning the first VC in the second row:

self.navigationController.delegate = self;
CGSize navBarSize = self.navigationController.navigationBar.bounds.size;
CGPoint origin = CGPointMake( navBarSize.width/2, navBarSize.height/2 );
self.pageControl = [[UIPageControl alloc] initWithFrame:CGRectMake(origin.x, origin.y+16,
                                                                   0, 0)]; //Here added 45 to Y and it did the trick



self.pageControl.pageIndicatorTintColor = navbarColor;
self.pageControl.currentPageIndicatorTintColor = [UIColor lightGrayColor];

[self.pageControl setNumberOfPages:2];

and

- (void)navigationController:(UINavigationController *)navigationController     willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
    int index = [self.navigationController.viewControllers indexOfObject:viewController];
    self.pageControl.currentPage = index;  }

Which gives me this result:

Which is perfect, I can swipe right and left and the PageControl shows the right indicator etc. However when i leave the "UIPageViewController" meaning when i click back. The PageController still appears in the first VC in the first picture. Why does it tag along and not get removed and how can i solve this?

If you need extra codes / pictures that would make it easier to understand just tell me. Thank you!
