我以下列方式呈现视图控制器:
let vc: ChangeDateViewController = storyboard!.instantiateViewControllerWithIdentifier("changedate") as! ChangeDateViewController
let navigationController = UINavigationController(rootViewController: vc) //ensures that the top navigation bar remains in the new View Controller
self.presentViewController(navigationController, animated: true, completion: nil)
出于某种原因,在新的View Controller向上滑动时,呈现View Controller的基础会向下滑动。尽管演示有效,但看起来确实很小,因为向下滑动会显示视图背后的黑色背景。这是一种常见现象吗?我能做些什么来阻止它吗?
答案 0 :(得分:0)
试试这个:
let storyboard1 = UIStoryboard(name: "Main", bundle: nil)
let conn = storyboard1.instantiateViewControllerWithIdentifier("changedate") as! LMAddaccountMainVC
self.presentViewController(conn, animated: true, completion: nil)
这可能有助于解决您的问题。
