I have the following ViewController
:
class PageContentViewController: UIViewController {
var pageIndex: Int
}
How would I access pageIndex
from another ViewController?
I need to access pageIndex
in this function:
func pageViewController(pageViewController: UIPageViewController!, viewControllerBeforeViewController viewController: UIViewController!) -> UIViewController! {
//var index: Int
//index = ?
NSUInteger index = ((PageContentViewController*) viewController).pageIndex; // in Swift?
if ((index == 0) || (index == NSNotFound)) {
return nil;
}
index--;
return [self viewControllerAtIndex:index]; // in Swift?
}
Everything by default in swift is public, and thus if you declare something like this:
class SomeViewController: UIViewController {
var someVariable: SomeType = someValue
init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}
}
You can access it as long as you have an instance of it:
var myCustomViewController: SomeViewController = SomeViewController(nibName: nil, bundle: nil)
var getThatValue = myCustomViewController.someVariable
