以全屏显示视图不起作用

Question

我试图呈现一个从底部到顶部显示的视图。这是我的代码

let myPageViewController = storyboard?.instantiateViewController(withIdentifier: "myPageViewControllerID") as! MyPageViewController
myPageViewController.modalPresentationStyle = .fullScreen
let navController = UINavigationController(rootViewController: myPageViewController)
navigationController?.present(navController, animated: true, completion: nil)

尽管我正在使用.fullScreen，但该视图并未全屏显示。我尝试使用 peformSegue 来显示此代码的视图

self.performSegue(withIdentifier: "myPageViewSegue", sender: nil)

页面全屏显示，但从左到右，而不是从下到上。

我试过的第三个代码是这个

let detailVC = MyPageViewController()
let navigationController = UINavigationController(rootViewController: detailVC)
navigationController.modalPresentationStyle = .fullScreen
present(detailVC, animated: true)

在这里我得到一个错误Application tried to present modally an active controller。我试图在消失 MyPageViewController 时添加 self.dismiss 但它没有帮助。

Answer 1

问题可能是你没有展示 navigationController 你正在展示细节 vc，使用这个

'let detailVC = MyPageViewController()
let navigationController = UINavigationController(rootViewController: detailVC)
navigationController.modalPresentationStyle = .fullScreen
present(navigationController, animated: true)'

如果问题仍然存在，请使用

navigationController.modalPresentationStyle = .overCurrentContext
