Adding a NavigationBar to UITableViewController programmatically? - iphone

Question

I am trying to create a uitableviewcontroller as a modal viewcontroller to edit some settings. I am creating the tableviewcontroller in code and the thing i am struggling with currently is how to correctly add a navigation bar to the controller which will have a "Done" button on it that:
a) doesnt appear on top of the tableview and
b) does not scroll with the tableview??
This happens when i add the navbar to the contoller with:
[self.view addSubview:navigationBar];
This adds a navbar to the controller which goes on top and obscures the tables first row and also scrolls with the view?
I also thought about simply using a uiviewcontroller with a separate tableview however i like the funcitonality of automatically scrolling the tableview when editing a textfield that the tableviewcontroller gives you. Just cant figure how to setup this navbar??
thx

Answer 1

Just create UINavigationcontroller as the modal viewcontroller, and add the tableview as its root view controller.

Answer 2

Use Navigation controller as modalviewController(as suggested in the other answer). Here is the code:
UINavigationController *Controller = [[UINavigationController alloc] init];
//LoginViewController is a sub class of UITableviewController
LoginViewController *controller = [[LoginViewController alloc] init];
Controller.viewControllers=[NSArray arrayWithObject:controller];
[self presentModalViewController:Controller animated:YES];
[controller release];
[Controller release];

In Swift:
AppDelegate.swift
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
/*
#1. Instantiate a navigation controller and add the table view controller
as a child view controller.
*/
let navigationController = UINavigationController()
// Instantiate your desired ViewController
let storyboard = UIStoryboard(name: UIStoryboardName.Main.rawValue, bundle: nil)
let tableViewController = storyboard.instantiateViewControllerWithIdentifier("TableViewControllerID")
navigationController.addChildViewController(tableViewController)
/*
#2. Then we set the title of the navigation bar and add two bar button items.
*/
// We set the title of the navigation bar.
tableViewController.navigationItem.title = "My Title"
// Create left and right button for navigation item.
let leftButton = UIBarButtonItem(title: "Save", style: UIBarButtonItemStyle.Plain, target: tableViewController, action: "saveButtonClicked:")
let rightButton = UIBarButtonItem(title: "Right", style: UIBarButtonItemStyle.Plain, target: nil, action: nil)
// Create two buttons for the navigation item.
tableViewController.navigationItem.leftBarButtonItem = leftButton
tableViewController.navigationItem.rightBarButtonItem = rightButton
/*
#3. To finish we set the root view controller with the navigation controller.
*/
self.window?.rootViewController = navigationController
self.window?.makeKeyAndVisible()
return true
}
TableViewController.swift
// Method called when the user clicks on the Save bar button item.
func saveButtonClicked(sender: UIBarButtonItem) {
// Do something.
print("Save bar button item has been clicked!!!")
}
