I just created a new xcode project with the 'Tabbed Application' template. I have a tabbed application with two tabs therefore two controllers. Both controllers are of type UIViewController. I made one of my controllers the 'settings' controller. I added a nav bar with a title of 'Settings'. All is well so far.
Then I add a TableView to the settings controller and make it a static table. Apparently I cannot have a static table view inside of a normal ViewController, it needs to live in a TableViewController.
Here is where I get very lost (still very new to iOS programming).
Am I supposed to delete the ViewController that the template provided and add a new TableViewController? I tried this however I cannot add a navbar to this type of controller.
Or is there some way to shove a TableViewController into the ViewController to get things to work.
I have looked all over today and most examples of TableViewControllers I have found are not in a tabbed application so they just create a TableViewController and move on.
Oh I also need to be compatible with iOS 5. Not sure if that makes a difference with TableViewController stuff.
Any help would be greatly appreciated.
Thanks.
Update: other option: you can follow this tutorial too.
Yes, of course you can:
Delete de UIViewController
Add to your storyborad a new TableViewController
Select it and go to Editor Menu->Embed In->Navigation Controller
Connect it to your tabbar in the storyboard
Update: other option: you can follow this tutorial too: Tutorial: Storyboard in XCode 4.2 with Navigation Controller and Tabbar Controller (Part 1)
Hope it helps!

I have the following setup in my app:
My initial view controller is a UITabBarController.
the tabs:
1)UINavigationController->PostListVC
2)UINavigationController->CategoriesListVC
3)UINavigationController->PostListVC
4)UINavigationController->PostListVC
5)UINavigationController->MoreViewController
As you can see, 3 tabs contain the same viewController class, but should not contain the same view controller object - the view will display different information based on information he gets form the AppDelegate.
What I did is I created 5 UINavigationControllers, connected them to the uitabbarcontroller, then created a rootViewController segue for 3 of them to the same PostListVC View - that way I don't need to maintain 3 designs of the same view.
The problem that I get is that only the first PostListVC gets created properly ( the leftmost in the tab bar ) - the other tabs that point to a PostListVC just show a black screen.
I've tried to illustrate the way I wire-up the storyboard using a 3-tab example:
As you can see, both the upper-most and lower-most views are connected to PostListVC.
I do not know what the issue is. I assume I'm using storyboards somewhat wrongly.
Does anybody know how I can fix this?
Thanks!
EDIT:
I have created a simple, example project (Xcode 5) that illustartes this issue:
http://www.speedyshare.com/Srwfg/TabBarProblem.zip
EDIT 2:
A modified version of the example, showing the problem with the offered solution:
http://speedy.sh/JkdGC/TabBarProblem-2.zip
There is no way to create different tabBarItems with this method, and there's no way to place the barItems so that they're not in a row - even if you try to chagne the order of segues.
As you said you need three different instances of PostListVC then you should create three different viewcontrollers of type PostListVC and connect each tab to its own. The class is the same but each tab gets its own instance.
I have got your example program to work BUT I don't know if the solution will work for your full project. Hopefully, it will put you on the correct track.
The solution is to have ONE (1) Navigation Controller / embedded root view but TWO (2) segues from the Tab Bar Controller. Here's the picture:
It looks like there's a problem with multiple UINavigationControllers linking to the same UIViewController. But no problem with the same UINavigationController linking to the same UIViewController provided they are instantiated separately through the UITabBarController.
I have a UITabBarController inside of a TabBarViewController. I want to use this to connect my three other view controllers to a tab bar.
What I have so far: I have my three view controller, each with one UIView inside of them, ready to be paired with the tab bar to give easy navigation between them. I have also made a new Objective-C class of type UITabBarController. Inside the .xib of that I deleted the UIView and replaced it with a UITabBarController (not sure if this is right).
I'm new to Objective-C and Xcode so I don't know a whole deal about it all, so I may be doing this all wrong. Please correct me and try not to be too vague, thank you!
There's a tutorial here with two tabs:
http://www.youtube.com/watch?v=NfEK9JsCyXM
You can watch it and work with it to make it do 3 tabs.
I would like to ask something, because as a beginner I do not have any idea anymore
how it could work.
First of all I made a new project, a single view one and added a simple map view.
This worked very well (following a tutorial of course)
Now I tried to add this simple map view to my inital project, which is a tabbed based on with navigation controller.
In this tabbed application I already added two more views with view controllers, and I called them thirdview Controller and forthview controller. The vc's I gave the class thirdview and forthview controller.
So, now I wanted to make the mapview on the thirdview. I did exactly what I did in my "trial project" but it is not working. Well, when I run the simulator I see a map. But it does not show the location as I have specified it inn the thirdview controller.m
Because it was working in the singleview project, I guess I have something to add or to connect in my inital tabbed application?
I would be greatful for any help on this
Thanks a lot
What you have there, as I can see from what you say, is a very simple and litle forget made by everyone who begins with xCode :)
Try to link your viewControllers and your map (in the xib or Storyboard) to your file's owner' view and delegate.
by default, these aren't linked. Just right click on it and drag your View and delegate to your file's owner.
Also, be sure that each of your viewControllers' classes are really thirdview and forthview in the properties (don't be confused with xib identifier!)
Hope this helped you! Feel free to ask if anything is missing :)
I've reviewed many websites and youtube videos that have IOS 5 storyboarding information. Most of them are pretty basic and only describe how to get started with storyboarding and how to segue into other views. I'm interested in taking it a step further and actually adding custom code to the views contained within the storyboard.
Is the "normal" workflow when creating an IOS app using storyboard?
Create the layout of an app using storyboard (adding views and objects to those views).
Create viewcontroller files (.h and .m), one for each view contained within the storyboard.
Hook up the scenes from the storyboard with your own view controller subclasses by editing the "class" values in Identity Inspector.
I believe I followed those steps, but when I implemented step #3 above and ran my application, I was only able to see a black screen. The view I had created in storyboard wouldn't display.
You have the right steps. Make sure you create your .m and .h without a xib. Post your code for the view controller for your first view to get more help.
yes, this is the normal workflow. have you set the "initial viewcontroller? ?

It sounds like you made a storyboard file but it isn't being loaded.
Do you have the main storyboard setting in the target summary screen filled in?
So all I want to do is create an App that has two pages: one with a button that opens up a UIWebView in the second. It seems simple enough, yet I have spent the past two days trying to figure it out.
I create the object and put in the code for the link and ctr - drag the web-view to the controlview.h but nothing will work.
Does anyone know a tutorial or can explain this to me? I have been searching the web for the pat two days and have gotten nowhere. thank you.
Each "page" should be a separate view controller. You open the storyboard editor, drag a view controller to it, drag a web view to your new view controller, then drag a segue from the appropriate control on the first page to the second page.
You will also need to create a UIViewController class for the second page, and set the controller's identity in the storyboard editor. (Select the second controller, type command-option-3, enter the view controller's class name in the "Custom Class" section.)
In the second view controller you will need some code to make the webview do something, obviously, so you probably will want to create an outlet for the webview.
Maybe you should start out with this general guide on View Controllers. You'll learn how to use View Controllers and how to present Modal View Controllers.
After that you go on with the documentation about UIWebView.
If you do a quick search for UIWebView you'll find tons of tutorials, but basics are important :)
CONTROL+DRAG does not work on storyboard. When I click view and drag to UIWebView, it opens a black popup but I cannot see my web value. I just see "view".
It does not work on storyboard either. I tried it on xib and it works with that.
