How do I add a Navigation Bar to a UITableViewController in Interface Builder?

Interface builder does not let me click and drag a Navigation Bar onto a Table View Controller!!! It is super frustrating.

All I want is a table view with an开发者_运维百科 edit button (done in interface-builder). If this is not possible, then how do I add a navbar progammatically?

From the outline view, make sure your Table View Controller is selected.

Then go to the Editor menu, and click on the Embed In submenu, and choose Navigation Controller and voila. You have your navigation controller pointing to your tableview controller with a relationship built in.

For a table view with an edit button at the top, use a UINavigationController, with a UITableView as the rootView. That means you're going to make a custom UITableView subclass for your table view, and use that as the rootView of your UINavigationController instance. (Programatically, it's set with UINavigationController's -(id)initWithRootViewController. It's also settable through IB.)

Then, in your UITableView subclass, uncomment the following line:

- (void)viewDidLoad {
    [super viewDidLoad];
    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
}

and voilà, your UINavigationController's view shows up as a table view with an edit button on the right side of the navigation bar.

Since the controller is at the top of the stack, there's no "back" button on the left, so you can use self.navigationItem.leftBarButtonItem for whatever UIBarButtonItem you create.

I agree that it's difficult to figure out how to do things like this in Interface Builder, but luckily it is possible to add a Navigation Bar and Bar Button Item to a Table View this way. Here's how to do it:

1. Drag a blank View (an instance of UIView) from the Library to the area near the top of the Table View. As you drag near the target area, Interface Builder will highlight it in blue to show you where to drop the View. Let go, and the View will be added as a subview of the Table View's header view.
2. Drag a Navigation Bar from the Library and drop it on the blank View you just added.
3. Drag a Bar Button Item from the Library and drop it onto the Navigation Bar.

EDIT

The problem with the above approach is that, as Bogatyr points out, the Navigation Bar will then scroll along with the Table View. Apple recommends using a custom subclass of UIViewController that owns both the Navigation Bar and an instance of UITableView resized to fit. Unfortunately, that means you would have to implement the UITableViewController behavior needed by your UIViewController subclass yourself.

Another approach that seems to work well is to create a custom subclass of UIViewController that owns a blank background view containing the Navigation Bar as well as a blank content view (an instance of UIView) that fits under the Navigation Bar. Your custom subclass would have an outlet pointing to an instance of UITableViewController in the same nib file.

This has the advantage of allowing all the view components to be created and configured in Interface Builder, and doesn't require implementing UITableViewController methods from scratch. The only detail you'd need to take care of in the Table View Controller's parent would be to add Table View as a subview of the parent's content view in viewDidLoad.

The parent could implement the action methods for the Navigation Bar's button items, and implement the delegate pattern if necessary.

From iOS6 onwards, you can use container view. So what you have to do is take View controller, add the navigation bar to it, then add a Container View to same view controller. It will automatically, add the new view controller link to your container view. Now simply delete that, and your table view controller in the story board. Now embed the table view controller to container view by control drag. Hope it helps.

First add a navigation controller and put the table view controller (as root view controller) onto the navigation controller. This is how it is done in Code because I don't use IB.

Why in the world you can't drag a navigationItem into a .xib file with File's Owner set to a subclass of UIViewController and hook the navigationItem up to the UIViewController's navigationItem outlet is beyond me. It seems like a real hole in IB / XCode integration. Because you can certainly drag an instance of ViewController to a xib file, and drag a navigationItem into the ViewController, and then set the title and barbuttonitems that way.

So if you want to define your UITableViewController subclass object's navigation bar in IB, you have to create your TableVC object in a xib file (not the one .xib file that contains the tableview for your UITableViewController, though!). You then either hook the TableVC object up to be an outlet of another object (like your application delegate), which works if you need just one instance of your TVC throughout the lifetime of your app, or if you want to dynamically create instances of your TableVC in code you load this extra .xib file manually via loadNibNamed:owner:options method of the NSBundle class.

These steps worked for me in iOS 9:

1. Add a View Controller to the Storyboard. Make UITableViewController as base Class.
2. Add a Navigation Bar object onto view controller at the top.
3. Add a Table View below Navigation bar.
4. Add a Table View Cell into Table View.
5. Add constraints.

This is the other easy way ;

1. Choose your TableViewController screen on storyboard.
2. Click Size Inspector symbol on the right menu and find Simulated Size
3. Change Fixed to Free Form

You can add navigation bar easily.
