Swift -> Swift implements IOS interface jumping

There are two ways of interface jumping in iOS development, jumping up and down and jumping left and right.

Jump up and down _TO:

 

let secondViewController = SecondViewController()  
self.presentViewController(secondViewController, animated: true, completion: nil)

  

 You can also directly self.present();

 

 

Jump up and down _BACK:

 

dismissViewControllerAnimated(true, completion: nil)  

 You can also directly self.dismiss()

Jump left and right_TO:

(Push the new view controller into the navigationController, which is equivalent to the push operation)

 

 

let secondViewController = SecondViewController()  
self.navigationController!.pushViewController(secondViewController, animated: true)

 

 

 

Jump left and right _BACK:

(removes the current view controller from the navigation view controller stack, thus returning to the previous interface)

(-) BACK_ to the previous level:

let firstViewController = FirstViewController()  
self.navigationController?.popViewControllerAnimated(true)

  

 

(-) BACK_SPECIFY INTERFACE:

 

// Get a view controller in the view controller  
let viewController = self.navigationController?.viewControllers[0]  
self.navigationController?.popToViewController(viewController as! UIViewController, animated: true)

  

 

 

(-) BACK_ROOT VIEW:

 

self.navigationController?.popToRootViewControllerAnimated(true)  

 

 

The settings of the root view need to be set in AppDelegate:

 

var window: UIWindow?  
  
  
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool  
{  
    var firstViewController = FirstViewController ()  
    var rootNavigationViewController = UINavigationController(rootViewController: firstViewController)  
          
    self.window!.rootViewController = rootNavigationViewController  
          
    return true  
}
