1. Three Methods of listening:

2. When you delete the original ViewController on the storyboard and add the NavigationController, It is not automatically set to initial View Controller. You need to manually set it.

3. The push method is no longer recommended. The show method is equivalent to the previous push method.

4. If you drag a button to another ViewController, it is automatically executed. If you want to establish a segue between the Controller and the Controller, you need to set the identifier of the sugue, and then you need to call the performSegueWithIdentifier method of the Controller in the method of the source controller class to achieve redirection. The latter can be verified before transmission.

5. Complete mseguewithidentifier: sender: complete execution process of the Method
