How to Get Navigation Based Template Functionality in Swift Programming

How to get navigation based template functionality in Swift programming

I would like to replicate your idea into what I usually do in the following example.

This is how my storyboard looks like:

As you can see login/signup and Tab bar is not connected with any kind of Segue.

Here Sign in Navigation controller is setup of Initial Controller.

Assign This Navigation Controller an Storyboard ID(e.g.LoginNavigation):

Do the same with Tab Bar Controller, assign Storyboard ID(e.g. HomeTabBar)

Now, you just have to shuffle Root View Controller of the app between Login Nav and Tab Bar.

So if user successfully logs in, changes the application's root view to HomeTabBar using following code:

let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let home: UITabBarController = storyboard.instantiateViewControllerWithIdentifier("HomeTabBar") as! UITabBarController
appDelegate.window?.rootViewController = home

And when user logs our, again change the root view to Login Nav:

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let entryPoint:UIViewController = mainStoryboard.instantiateViewControllerWithIdentifier("LoginNavigation")
appDelegate.window?.rootViewController = entryPoint

The appDelegate is defined in my constants.swift file :

let appDelegate  = UIApplication.sharedApplication().delegate as! AppDelegate

Better way to identify if a viewController was reached by popping the navigationController or using the tab-bar

So to recap, there seems to be no way outside storing the fact that the push was performed as a state. From the answers provided below, this state can be set by implementing the UINavigationControllerDelegate and using the navigationController:willShowViewController:animated:method:

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
    self.disappearedDueToPush = !(viewController == self);
}

If implementing the delegate seems a bit heavy handed (it did to me) you might up the following in your viewDidDisappear method instead:

if (self != [self.navigationController.viewControllers lastObject]){
    self.disappearedDueToPush = YES;
}

This made more sense to me as the reverse logic (and checking towards the fact) is performed in the viewWillAppear method.

Segue Presently from Appdelegate to UITabBarController in swift

You need to set your viewControllers instead of pushViewController

rootViewController.viewControllers = [viewController]

Instead of

rootViewController.pushViewController(viewController, animated: true)

Tab bar controller inside a navigation controller, or sharing a navigation root view

The two previous answers got it right - I don't use UITabBarController in Tweetie. It's pretty easy to write a custom XXTabBarController (plain subclass of UIViewController) that is happy to get pushed onto a nav controller stack, but still lives by the "view controller" philosophy. Each "tab" on the account-specific view (Tweets/Replies/Messages) is its own view controller, and as far as they are concerned they're getting swapped around on screen by a plain-ol UITabBarController.

Upon further research, decided that this was not feasible to do.
