ios - 无法转换“[AnyObject ]'to expected argument type ' [UIViewController]”类型的值？

Question

private func createPageViewController() {
    let pageViewController = self.storyboard?.instantiateViewControllerWithIdentifier("PageViewController") as! UIPageViewController
    pageViewController.dataSource = self
    pageViewController.delegate = self

    if contentImages.count > 0 {
        let firstVC = self.getItemController(0)!
        let startingVCs: NSArray = [firstVC]
        pageViewController.setViewControllers(startingVCs as [AnyObject] as [AnyObject], direction: .Forward, animated: false, completion: nil)
    }

Answer 1

改变这个

pageViewController.setViewControllers(startingVCs as [AnyObject] as [AnyObject], direction: .Forward, animated: false, completion: nil)

进入

viewControllers 参数现在是 [UIViewController]。因此，您传入的 viewControllers 数组必须是 [UIViewController]。

pageViewController.setViewControllers(startingVCs as [UIViewController], direction: .Forward, animated: false, completion: nil)
