I have an iOS app written in Swift with UITabBarController with 5 UIViewControllers. Now, I have a bunch of UIViewControllers that are not part of the UITabBarController. I'd like to be able to show that same tabbar but I have no idea how to do that. Any clue?
More details: This is one of the View Controllers that the tabbar has. I use storyboard references and split my view controllers into separate more manageable storyboards.
So, the big picture:
There's no initial ViewController since I use storyboardId to get to the initial Navigation Controller. From there we have a ViewController embedded in the same Navigation controller. In that ViewController, there are 2 Container views - one of the size of the bottom ViewController that contains the "hamburger" button that toggles the other Container View which has an embedded UITableView in. When a specific cell is selected it should go to Profile ViewController that's not even in the same storyboard. The segue is set to be Push. Either way, doesn't show the UITabBar on the Profile ViewController
how you doing?
I don't know if I understood, but you are trying to show tabbar after going to another screen, right? If the answer is 'yes', try to change your segue to show(e.g. push).
-----Edit-----
You can do with two ways:
Presenting Modally -> using Current Context
Use push(e.g.) with a navigation view controller, you can also hide the navigation bar if you go to Navigation controller -> Attributes inspector -> Navigation Controller -> Uncheck Shows Navigation Bar
Hope now it works!
Best regards
In xcode what is the difference between dragging a Table View vs dragging a Table View Controller on a view in a xib?
Same thing with dragging a Tab Bar vs a Tab Bar Controller?
A UITableView is a view that must be hooked up to a controller somewhere in order to control it's contents, while a UITableViewController is a pre-built controller that you can subclass that has a table view.
A tab bar needs a controller as well, and UITabBarController provides a pre-built controller. You can also build your own.
How would I set a UITabBarController with all its individual view controllers as the root view in a split view? IB doesn't seem to let me change the class of the root view controller to anything else…I'm using Xcode 4.
Are you using the split-view based application-option? In that case, it worked for me to just extend : UITabBarController in the RootViewController.h-file. I'm not sure what behaviour you want here, but if you set it up like that, you should get the tabbar with all your views (you have to add them in RootViewController.m ofc) in the "root"-option on the navigation bar.
If you want the DetailView to show the same, you have to add a navigationcontroller to the detailview as well.
As for the "more elegant" solution with IB, I'm afraid I'm not very fond of or very experienced with IB.
You want to add tabbarcontroller to your split view at rootview side and its very simple.
create as many viewcontrollers subclasses with xib for ipad as u want to put in tabbarcontroller.
Then expand your splitview , u have two things navigationcontroller(which in turns contain rootview controller),detailview controller(right side view).
Open your library just drag tabbar controller exectly onto navigationcontroller ,so it will replace all that navigation controller and rootviewcontroller(i assume u dont need that rootview controller or u can create it later).
now expand this tabbar controller u can see viewcontroller 1 - viewcontroller 2 etc.
Now simply select view controller 1 , open attributes and select nib file on [command 1 attribute] and select controller file for that nib file by press[command 4 attribute].
Reapet this for view controller 2 in tabbarcontroller and save close IB.
run program select landscape then u can see its done.
Thanks to dh14-sl and lecou—the solution was a combination of both your answers. I was trying to drag a tab bar controller from the library onto the list of elements but it wasn't working—turns out I had to drag it to the view itself. Then I had to change the parent class of my rootvc and re-setup connections, but now it seems to work! Thanks guys!
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 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:
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.
Drag a Navigation Bar from the Library and drop it on the blank View you just added.
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:
Add a View Controller to the Storyboard. Make UITableViewController as base Class.
Add a Navigation Bar object onto view controller at the top.
Add a Table View below Navigation bar.
Add a Table View Cell into Table View.
Add constraints.
This is the other easy way ;
Choose your TableViewController screen on storyboard.
Click Size Inspector symbol on the right menu and find Simulated Size
Change Fixed to Free Form
You can add navigation bar easily.
How exactly does one go about implementing a custom toolbar for the main table view section of a split view?
The program I am writing for the iPad is landscape only so the split view has a static table view along the left side, and at the top is the toolbar with a title. It is this toolbar I would like to change. I have created the split view controller, table view controller, and detail view controllers programmatically so I should have reference to the toolbar object. The only thing is I don't know how to reference it so I can overwrite it with my custom toolbar.
Is it the split view controller that creates this toolbar? Or the table view?
Any ideas?
It's a navigation bar, not a toolbar. You'll want to investigate the navigationItem property of the UIViewController responsible for the view with the navigation bar. This is an instance of UINavigationItem; see the documentation here: UINavigationItem.
