App with Login page and then NavBar + Table View + Tab Bar

[idesiteacher]

Gurus,

I'm trying to develop an sample app, having the following features.

- Application starts with an Logon on page: User ID, Password and Logon button
- On clicking the logon button, after validating the credentials, we've to take the user to the next screen with
- an Navigation Bar on the top (essentially an UINavigationController)
- Table view
- Tab Bar in the bottom

Without the logon page, I'm able to create the app, by following the steps given by DevTeamOfOne at this post. However, not sure how can I achieve it having an logon screen at first.

Could anyone help please?

Thanks

You have two way to achieve this.
First, Set the login screen as the mainviewcontroller. after login add navigation view to the main view.
Second, Set the login screen as the root view for the navigation view. hide the navigation bar on the root view.

Can someone show a code sample for no. 1?

Add a modalviewcontroller on startup on top, and if the credentials are correct after pressing login, dismiss it, so user can use the app. Not that hard I guess..

this is how i achieve #1 in my application, i dont load up the tabBarcontroller initally when the application loads. first i load my log in controller, then when the server sends back a messege stating if the user has logged in or not then i show my tabBarcontroller

in your applicaitons delegate you have these lines of code in the - (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary *)launchOptions method

[self.window addSubview:tabBarController.view];
[self.window makeKeyAndVisible];

;

now just place an object of your log in view controller before these lines of code and add it to the window like so

MyLogInController *logInVC = [[MyLogInController alloc]initWithNibName:@"MyLogInController" bundle:nil];
[self.window addSubview:logInVC.view];
[self.window makeKeyAndVisible];
return YES;

;


In this example I have a tabController so just place the tab controller on the window after you have completed validating users log in info like so

1)make a reference to the application delegate
2)add tabBarController to view

MyApplicationDelegate *del = (MyApplicationDelegate)[[UIApplication sharedApplication]delegate];
[del.window addSubview:tabBarController.view];

just make sure you release the log in view controller before you do it or it will just be sitting in the background using memory
