How to use code to call storyboard

Switch from network:

 

1. Get a storyboard object (the uistoryboard class object ).

If you have an existing View Controller that is instantiated from the same storyboard, you can obtain the storyboard object through its storyboard attribute. To load another storyboard object, you can call the class method storyboardwithname: Bundle: Of the uistoryboard, and pass the file name and an optional bundle of the storyboard as parameters to this method.

 

2. Call the instantiateviewcontrollerwithidentifier method of the storyboard object to pass the identifier defined when you create the View Controller in interface builder to this method.
