问题
I am wanting to create a modal segue from a view controller to an a new view, but not by linking the segue action to a button or anything. Instead, I'd like to just set the segue up so that I can call it in pageDidLoad and have it automatically execute if I want.
To do this, I need to be able to reference the segue, such as this:
[self performSegueWithIdentifier:@"mySegue" sender: ...];
After I control-click-drag a connection in storyboard to create a segue, how can I give it a name for later reference? Thanks!
回答1:
Link the segue action from curent viewController to new view controller. I think this you want, see the screenshot.
This link will help you for remaining code.

Nevermind! In the details pane sidebar of xcode, under the third tab there is an "Identifier" field that can be filled out!
