Answer 1

this code is in Swift Add following in your UIPageViewController

override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

    for view in self.view.subviews {
        if view.isKindOfClass(UIScrollView) {
            view.frame = UIScreen.mainScreen().bounds
        } else if view.isKindOfClass(UIPageControl) {
            view.backgroundColor = UIColor.clearColor()
        }
    }
}
