ios - 呈现 View Controller 的最佳方式

Question

我正在研究多个框架，我的问题只是一个“哲学”问题。

我创建了一个实用函数来显示 View Controller

static func presentViewController(identifier: String, storyboardName: String = "Main", presentationStyle: UIModalPresentationStyle = .fullScreen){
    let storyboard = UIStoryboard(name: storyboardName, bundle: InternalConstants.bundle)
    var viewResult: UIViewController
    if #available(iOS 13.0, *) {
        viewResult = storyboard.instantiateViewController(identifier: identifier)
    } else {
        viewResult = storyboard.instantiateViewController(withIdentifier: identifier)
    }
    viewResult.modalPresentationStyle = presentationStyle
    var top = UIApplication.shared.keyWindow?.rootViewController
    while top?.presentedViewController != nil {
       top = top!.presentedViewController
    }
    top!.present(viewResult, animated: true, completion: nil)
}

首先，这是呈现 View Controller 的正确方式还是有更好的方式？

那么，在导航 Controller 中呈现 View Controller 是否更好？

Answer 1

First of all, is a correct way to present a view controller or there is a better way?

而不是一个实用程序使它在里面

 extension UIViewController {
   func ......
 }

Then, is better to present a view controller in a navigation controller or not?

nav 面向 push/pop 但用它来呈现另一个 vc 也没有错
