Main. storyboard

How can I obtain the specified viewController from a viewController when I use storyboard for iOS development?

UITableViewController * startingTableController = [self. storyboardinstantiateViewControllerWithIdentifier: @ "UITableViewController"];

[Self. view addSubview: startingTableController. view];

// InstantiateViewControllerWithIdentifier: The Identifier (Identifier) that defines the attributes of the form during design );
// [Self. storyboardinstantiateViewControllerWithIdentifier: @ "UITableViewController"]; it returns a controller object
// [Self. view addSubview: startingTableController. view]; Add the Controller view to the main window view. The disadvantage of this is that there is a blank area, which seems to be
The error message returned when the startingTableController taskbar is missing.

Set [self. view addSubview: startingTableController. view];
For

NSArray * viewController = [NSArray arrayWithObject: startingTableController];
[Self. pageViewController setViewControllers: viewControllerdirection: UIPageViewControllerNavigationDirectionForward animated: NO completion: NULL];
[Self addChildViewController: self. pageViewController];
[Self. view addSubview: self. pageViewController. view];
Can solve the blank Problem
 
How does IOS storyboard achieve two different viewcontroller jumps through judgment?

Storyboard is only used for interface layout, and the real judgment must be implemented in the code. NavigationController: push the viewcontroller according to the judgment. The code is better written by yourself, and the impression on yourself is the most profound. You can only remember what others wrote when you use it. You will never forget it for a while.
