I have a page view controller with array referencing storyboards ID of controllers, that I want to show inside. How can I pass data from root controller to controllers indside ?
I tried do to like this but it fails
func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
if let index = pages.indexOf(viewController.restorationIdentifier!) {
if index < pages.count - 1 {
return viewcontrollerAtIndex(index + 1)
}
}
var objectController = viewcontrollerAtIndex(0) as! HF2Object
objectController.object = object
objectController.serverID = serverID
objectController.imageURLsArray = imageURLsArray
return nil
}
Whole controller code
import UIKit
class HF2PageViewController: UIViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {
var pages = ["object", "reviews"]
var pageViewController = UIPageViewController()
var object:String?
var serverID:String?
var imageURLsArray = [String]()
override func viewDidLoad() {
super.viewDidLoad()
pageViewController = UIPageViewController(transitionStyle: .Scroll, navigationOrientation: .Horizontal, options: nil)
pageViewController.view.frame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 64, self.view.frame.width, self.view.frame.height - 64)
addChildViewController(pageViewController)
self.view.addSubview(pageViewController.view)
pageViewController.delegate = self
pageViewController.dataSource = self
pageViewController.setViewControllers([viewcontrollerAtIndex(0)], direction: .Forward, animated: true, completion: nil)
pageViewController.didMoveToParentViewController(self)
}
func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
if let index = pages.indexOf(viewController.restorationIdentifier!) {
if index < pages.count - 1 {
return viewcontrollerAtIndex(index + 1)
}
}
var objectController = viewcontrollerAtIndex(0) as! HF2Object
objectController.object = object
objectController.serverID = serverID
objectController.imageURLsArray = imageURLsArray
return nil
}
func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {
if let index = pages.indexOf(viewController.restorationIdentifier!) {
if index > 0 {
return viewcontrollerAtIndex(index - 1)
}
}
return nil
}
func viewcontrollerAtIndex(index: Int) -> UIViewController {
let vc = storyboard?.instantiateViewControllerWithIdentifier(pages[index])
return vc!
}
}
