Add Tabs To MasterView Controller Project - iphone

I created a MasterViewController project with a tableView, now I'd like to add some tabs to this. I tried to just drag and drop the tab bar into the MasterViewController and the tabs show, but they are linked the the last cell in the tableView.
Is there any way to make the tabs stay in place so they are always displayed? What I am trying to accomplish is to give the user buttons to push to organize the data in the tableView, so I'm open to other suggestions.
Here are the pictures:


You need to have your controller be a UIViewController, not a UITableViewController (where the table view is the controller's self.view, and is full screen). If you use a UIViewController, you can add a table view, and size it such that you have room at the bottom to add the tab bar. In that case, both the table view and the tab bar are subviews of the controller's self.view. The way you're trying it, the tab bar is added to the table's scroll view.


It sounds like you added it as a subview of the table view, so as the table view scrolls it scrolls too. Look at creating a container view to hold both the tableView and tab bar / segmented control / buttons positioned below it. You will need to make the controller a subclass of UIViewController instead of UITableViewController.
Alternatively, use the navigation bar to add some edit button(s), either to enter an editing mode which shows controls on each row or where the buttons actually edit the currently selected row.


Tab bars are container controllers and are used to present a different mode of your application. If you want to only organize your tableview data, my suggestion is to use UISegmentedControl.

Present view underneath another

I'm trying to pop up a view controller from the bottom of the screen but I want a view from its parent view controller to show on top of it so that it slides up from underneath this view. There's no interactivity with this extra view on top of everything. Is there a reasonably simple way to do this?

There are various ways to achieve this:
You can create a xib and add over the view controller.
You also create a programmatically view and add over the VC.
You also can drag view over the VC in storyboard and initially hide the view.
Show with the animation.

how should i add a textfield/button to a table view controller?

I have a UITableViewController with a nav bar up top from an embedded nav controller. In between the nav bar and the start of the cells I'm trying to add a textfield and button sort of like a search bar layout but for a different purpose.
On my storyboard, I can drag in a button or a label, but it automatically fills the width of the scene. As a result there is only room for one or the other. I tried editing with the size inspector in the right pane but it reverts to the old number everytime.
How would I pull this layout off?

Create a view with the label/text field and the button then drag the view to the top of the tableview. It will add the view as a header view.

How to "Dock" a UIToolbar to the bottom of the screen in UITableView?

I have a UIToolbar that I added to a UITableViewController in my Storyboard.
When this view is displayed, the toolbar will show itself directly below the last item in my UITableView. I want to "Dock" my toolbar on the bottom of the screen. I want it to display in the same place every time rather than move around depending on a variable number of table cells in my view. I need the user to be able to see all the cells as well (It can't be covering UITableView items, UITableView needs to decrease its allotted display space). How can I do this?
Edit: Using a UINavigationController to handle my views

You have a couple of options. The first and easiest of the two would be to use a UITableViewController embedded inside a UINavigationController, with the navigation controllers toolbarHidden property set to NO.
The other option is to use a UIViewController. A view controller has a UIView build in, and you can manually add and position a UITableView and a UIToolbar on it in this configuration. Both of these configurations will achieve your desired end result.

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 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.

Last row in UITableView is obscured by UITabBar

I have a UITabBarController that has a list of UINavigationControllers assigned to the 'viewControllers' property.
Each UINavigationController has a custom UIViewController as its 'rootController' and this custom UIViewController loads its 'view' from a .xib file. This 'view' contains a UITableView (and some other controls that are displayed when the data for the UITableView is first downloaded).
It works fine to begin with - I can see the table view for the first view controller when the first tab is selected, changing tabs displays the other table views - all is good.
My problem is, when I select a row on one of these table views a new custom view controller is instantiated, told to hide the bottom bar when pushed and then is pushed on to the navigation controller. Again - this works as expected. I see the new sub-view and the tab bar is hidden.
The problem is when I return to the previous view, the final row in my UITableView is now obscured by the tab bar (which has correctly reappeared). It seems the process of hiding the bottom bar and then showing it again when returning to the previous view has confused things.
Has anyone encountered this? Any idea what I might be doing wrong?

Check that your UITableView has not the UIViewAutoresizingFlexibleHeight (in IB, see the picture below).
