InstantiateInitialViewController和InstantiateViewControllerWithIdentifier之间有什么区别? [英] What's the difference between instantiateInitialViewController and instantiateViewControllerWithIdentifier:?

问题描述

如果我有一个故事板，其视图控制器已被标记.那么这两个API有什么区别?

If I have a storyboard whose viewcontroller has been tagged. then What's the difference between these 2 APIs?

我想知道的是返回的对象是否存在某些差异.它们是完全相同还是其中之一将初始化更多东西?

What I want to know is whether there is some difference on returned object. are they exactly same or one of them will initialize more things?

推荐答案

使用 instantiateInitialViewController:来初始化默认视图(初始)，这是您通常不会以编程方式执行的操作

Use instantiateInitialViewController: to instatiate the default view (initial), this is something you wouldn't do programmatically usually

在需要 ViewController 并使用 storyboard (storyboard ID(标识符))附加视图时，使用 instantiateViewControllerWithIdentifier :

Use instantiateViewControllerWithIdentifier: when you would like a ViewController And attach a view from the storyboard (storyboard Id (Identifier))
