Disable/enable scrolling in UIPageViewController

Question

I got a viewController which inherits from UIPageViewController ( @interface PageScrollViewController : UIPageViewController ) Now I\'

Answer 1

UIPageViewController manages a UIScrollView internally to get things done. We can find out that UIScrollView and update its isScrollEnabled property.

let view = myPageViewController.view
for subview in view.subviews {
    if let scrollview = subview as? UIScrollView {
        scrollview.isScrollEnabled = false
        break
    }
}

Or use this UIPageViewController extension.

extension UIPageViewController {

    var scrollView: UIScrollView {
        for subview in view.subviews {
            if let scrollview = subview as? UIScrollView {
                return scrollview
            }
        }
        fatalError()
    }
    
    var isScrollEnabled: Bool {
        get {
            return scrollView.isScrollEnabled
        }
        set {
            scrollView.isScrollEnabled = newValue
        }
    }
}
