[SWIFT] Screen transition method

Introduction

I designed it with 1 Storyboard — 1 ViewController in the application development in learning, but I noticed that I am always searching the net for methods for screen transitions, so I will post it as a memorandum.

The reason for designing with the above method is that the method of preparing one StoryBoard for one ViewController reduces conflicts in joint development.

Operating environment

【Xcode】Version 12.0.1 【Swift】Version 5.3

Implementation method (using navigationController)

python

//Get the transition destination View (NextViewController)
let storyboard = UIStoryboard(name: "Next", bundle: nil)
let nextVC = storyboard.instantiateViewController(withIdentifier: "NextVC") as! NextViewController
//Screen transition to NextViewController
self.navigationController?.pushViewController(nextVC, animated: true)

Implementation method (does not use navigationController)

python

//Get the transition destination View (NextViewController)
let storyboard = UIStoryboard(name: "Next", bundle: nil)
let nextVC = storyboard.instantiateViewController(withIdentifier: "NextVC") as! NextViewController
//Screen transition to NextViewController
self.present(nextVC, animated: true, completion: nil)

Implementation method (storyboard settings)

• Since the screen of Storyboard is instantiated, it is necessary to add Storyboard ID. Be careful not to forget to check Use Storyboard ID.

Summary

There are still many ways to change screens, so I hope to update them as needed.
