我应该使用哪个序列垂直显示视图控制器？

Question

First and foremost i'm still new to Swift so please bear with me. Say i'm at view controller A (which is the root view controller in the navigation hierarchy) and I want view controller B to appear as a popup (cover the entire screen). I want that popup and to remain part of the navigation hierarchy. Then from that popup push to view controller C with a horizontal transition. How would I do this? I am using segues. I just don't know which segue to use. Should I use a modal or popover segue to go from view controller A to view controller B? Or should I simply use a push segue and use a custom transition? I'd prefer not to use a custom transition but let me know what you think.

Answer 1

将ViewController B嵌入到导航控制器中，然后模态显示导航控制器。

Answer 2

Use the below code to present the VC from bottom.

let alertVC = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CustomAlertViewController") as! CustomAlertViewController

alertVC.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext

self.present(alertVC, animated: true, completion: nil)

Then further use push for other VC's
