The UIStoryboardclass is your friend:
该UIStoryboard班是你的朋友：
UIStoryboard* sb = [UIStoryboard storyboardWithName:@"mystoryboard"
bundle:nil];
UIViewController* vc = [sb instantiateViewControllerWithIdentifier:@"ExampleViewController"];

- If it is still in its own xib file, then you don't change anything.
- If you've moved everything into a storyboard, then you wouldn't often need to do this as you'd link between view controllers using segues.
- 如果它仍然在它自己的 xib 文件中，那么你不需要改变任何东西。
- 如果您已将所有内容移动到故事板中，那么您通常不需要这样做，因为您将使用 segue 在视图控制器之间进行链接。
If neither of the above are true, i.e. your view controller is on the storyboard but no segue connects to it, then you want UIStoryboard's instantiateViewControllerWithIdentifier:method described in the documentation. You have to set the identifier in the storyboard for this to work.
如果以上都不是真的，即您的视图控制器在故事板上但没有 segue 连接到它，那么您需要文档中instantiateViewControllerWithIdentifier:描述的UIStoryboard方法。您必须在故事板中设置标识符才能使其工作。
