Ios 在UIViewController中显示NavigationController

我有一个来自单元格的UICollectionView，它通过缩放动画连接到另一个UIViewController。我必须将其嵌入UINavigationController，但当它在模拟器中启动时，它不会显示UINavigationController。有什么问题？ 谢谢你的帮助

当您使用StoryboardId从情节提要引用ViewController时，它会忽略它可能嵌入的任何导航视图。因此，您必须执行以下操作。为了简洁起见，我省略了一些设置代码

let detailViewController: UIViewController = self.storyboard!.instantiateViewControllerWithIdentifier("FullPhotoController") as! FullPhotoController
let navigationController: UINavigationController = UINavigationController(rootViewController: detailViewController)
navigationController.modalPresentationStyle = .Custom
navigationController.transitioningDelegate = transitionDelegate

self.presentViewController(navigationController, animated: true, completion: nil)

“FullPhotoController”是UINavigationController吗？如果不是，则仅显示常规模态控制器。当我使用NavigationController，但动画不是缩放动画时，动画是显示细节（例如替换）。我可以在那里做什么？猜测缩放是由modalPresentationStyle=.Custom和transitioningDelegate=TransitionLegate处理的？如果是这样，只需执行在detailViewController上执行的操作，但将其应用于navigationController。我会更新答案。如果答案正确，请将其标记为已回答并进行投票。

let detailViewController: UIViewController = self.storyboard!.instantiateViewControllerWithIdentifier("FullPhotoController") as! FullPhotoController
let navigationController: UINavigationController = UINavigationController(rootViewController: detailViewController)
navigationController.modalPresentationStyle = .Custom
navigationController.transitioningDelegate = transitionDelegate

self.presentViewController(navigationController, animated: true, completion: nil)
