I have a UIViewController that allow me to display some text into a view.
I want to add an input method without add it directly into this view controller, this input method will be a button or a UITextField.
This input method will be a lot, but it will be use one at time chosing it from setting so a I won't to have a UIViewController that control all of this.
What I want is know how it's possible to split the output view (controller) with each input view (controller)?
You can image to have a text view on the top of the screen and some other view at the bottom and I will to separate the logic of the second view from the logic of the first one
Is it clear?
Of course it is possible to have 2 UIViewControllers on screen at any time! There are a few ways to go about this:
Using One Main View: Add the second ViewController's view as a subview
Using Interface Builder: Drag in a UIViewController Object, set it's class, then hook it's View outlet to a UIView in the first ViewController.
Child View Controller: As it's name implies, the -addChildViewViewController: method will add a new ViewController as well, then add it's view as a subview.
Yes, it's possible. Just add the controller as a child controller ([UIViewController addChildController:] and its view ([controller.view addSubview:childController.view]).

I've made a view in my storyboard which I've now decided I'd rather display its data via static table cells.
I can't use static table views in a UIViewController (Static table views are only valid when embedded in UITableViewController instances). So, I need to convert my existing UIViewController to a UITableViewController somehow. I've changed the .h file's parent, but that hasn't done it.
Is there another way to get this going? I'd really rather not have to make a new VC in the storyboard and move everything over, it's a big hassle.
I'll add to this, since the question is about how to change a UIViewController into a UITableViewController, and given that this question is over a year old and the original answer, while valid and may or may not have been the only solution at the time, doesn't actually answer the question and is not the only solution.
It IS possible to do this, you just have to set up the table view delegate and datasource outlets in IB, and manually edit the storyboard XML, which sounds scary but is actually very easy.
First, change your class's parent to be a UITableViewController. UITableViewController already adopts the UITableViewDatasource and UITableViewDelegate protocols, so if your class does too you can remove them:
#implementation MyTableViewController : UITableViewController
...
#end
Next, create new referencing outlets on your UITableView for its dataSource and delegate. The easiest way to do this is to control-drag from the UITableView to itself. The popup will give you the dataSource and delegate options.
Lastly, you need to change the storyboard XML. The storyboard file can get pretty big pretty fast. The easiest way to find the scene you are looking for is by setting Storyboard Identifier in the Identity Inspector. To view the XML directly, right click on the storyboard file in the project navigator and select "Open As -> Source Code". Now just search for whatever you set the reuse identifier to earlier. You'll see something similar to this:
<!-- My Table View Controller -->
<scene sceneID="EuE-XX-cCb">
<objects>
<viewController storyboardIdentifier="MY_TABLE_VIEW_IDENTIFIER" ... >
// Lots of other stuff
</viewController>
</objects>
</scene>
All you need to do is change the opening and closing view controller tags
<viewController>
</viewController>
to be tableViewController instead
<tableViewController>
</tableViewController>
That's it! No need to create a new UITableViewController scene or embed a UITableViewController in a container view.
EDIT:
I should also add that the UITableView MUST be the root view. It cannot be embedded inside another UIView.
If you want your static cell table view not to take up the entire screen, then using a container view is the easiest way to go. Start with a regular UIViewController and drag a container view (next to normal UIView in the object list) into its view. Resize it however you want -- the storyboard will automatically provide a view controller connected to this container view with an embed segue. Delete that controller, drag out a table view controller and right-drag from the container view to this table view controller to make a new embed segue. This table view controller can be accessed from the UIViewController with its childViewControllers property (and conversely, you can access the UIViewController from the table view controller with parentViewController if you need to).
What I did, is creating a UITableViewController in IB, open the Storyboard with a text editor, and copy all the nodes inside from the UIViewController to the UITableViewController.
I think that with this way there's less risk of deleting something important.
Before copying the sections objects, make sure that both tableviews (UIViewController and UITableViewController) have the same properties set like: static or dynamic cells, style (plain or grouped), etc.
I have a simple iOS 5 storyboard that contains a tableview controller scene. However, the table UI takes up 100% of the real estate and I am unable to add any additional objects such as a title bar. Any object that I drag to the scene will try to size correctly and what-not but as soon as I let go it will not add the object. What am I doing wrong?
If all you want is a title bar, then it looks like you want to embed your table view controller in a navigation controller. You can do this by selecting your table view controller and using the Editor: Embed In: Navigation Controller menu command. Once you do this, you should have a navigation bar, and you can double click it to edit the title.
If you need arbitrary UI elements along with your table view, then I think you need to use a plain UIViewController scene instead of a UITableViewController, and manually drag a UITableView into the scene. Your view controller would not subclass UITableViewController, instead it would subclass UIViewController and implement the UITableViewControllerDelegate and UITableViewControllerDataSource protocols. Also, you would need to manually wire up the delegate and dataSource outlets by ctrl-dragging from the table view to your view controller in interface builder, and your view controller would need a custom tableView outlet that points to the UITableView and is correctly wired up in IB. Perhaps there is a simpler approach than this though, if someone has a better suggestion that would be great to hear.
While creating a navigation based application, it automatically creates a root view controller which subclasses UITableViewController, but in MainWindow.xib as you know I can't see a UITableView is placed under root view controller but we drag and drop a table view there. Can we simply drag and drop a UIView instead of a UITableView and change the root view controller class to sublass a uiview instead of UITableView and change its methods?
Or I must drag a UITableView in IB for the root view controller? I am a beginner and I do not want to make complicated things so what is the simplest way of using a UIView as a root. If thats not simple I will stick with the table view.
Yes you can change. You just need to change some bindings in inteface builder and change rootViewController's superclass to UIViewController instead of UITableViewController.
UPDATE
First open the rootViewController.xib and delete the tableiew from there and drag-n-drop a UIView. Bind that View to view property in file-owner. Change superclass of rootViewController from UITableViewController to UIViewController. That's it.
Here are the screenshots.
I am trying to implement a popover view in a tableview controller. My intention is for the user to select an option from the table list as shown below.
Note that my popover view actually displays the data from a separate table view controller. I am creating the popover view controller via the following initialization method
self.popOverViewController = [[UIPopoverController alloc]initWithContentViewController:optionsTableViewController];
After the user selects an option for example "Hottest All Time", the control should be passed from the tableview Controller (in the popover view) back to the MAIN table view controller (parent view) so as to trigger a table reloadData method.
Query: Is there a way to return the control from the tableview controller in the popover controller back to the MAIN tableview controller?
Do I have to use a delegate method to do this?
The two approaches I've seen are roughly the standard sort of fare:
create a delegate protocol for the class type of optionsTableViewController, have the controller that creates the popover implement it and set itself as the delegate when issuing the popover
use the NSNotificationCenter (which actually fits the intended purpose of the thing if you've a one-to-many message, as may be the case if you've a popover with a setting that affects a bunch of different controllers and you don't really care which is visible when the user requests the popover)
I checked out Apple's example on how to exchange detail views in the UISplitViewController and it seems that they put the UIToolbar in every detail controller. Then, if the device is rotated, they hide the toolbar or show it and add a popover button which will show the root controller.
I'd like to adopt this pattern to show my root controller in a popover using a button in the toolbar, but unfortunately, my detail controllers are all UITableViewControllers and they do not allow adding other UI elements than a table view. So how do I deal with that? Is there an example around?

I think I figured out by myself: DON'T use a ´UITableViewController´ and a UITableView as root view in your NIB, as you cannot add a UIToolbar to the table view.
Instead: In the NIB, put a standard view and drag a UIToolbar and a UITableView on it.
Connect the standard view to the controller's "view" outlet.
Add another outlet and make it a UITableView. Connect the table view to it.
In the code: Let your controller inherit from UIViewController and not from UITableViewController.
Add a property to your controller to get the TableView to make it look compatible to UITableViewController.
public UITableView TableView
{
get { return this.viewTableView; }
}
Upon the viewDidRotate event you will have to adjust the table views width and height now (UITableViewController did that job for you before):
this.TableView.Frame = new RectangleF(0, 44, this.SuperView.Frame.Width, this.SuperView.Frame.Height);
The 44 pixels com from the parent view's toolbar.
I don't miss UITableViewController. I know there are some issues like automatic scrolling when editing, but in my case this is simply not needed.

Check out this example and the corresponding code. If I understand your question, this should show you how to do what you're looking to accomplish.
Also, just as an FYI to everyone, another MT user MonoTouched the MultipleDetailViews example that you linked to above.
