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 am following the tutorial here. I just created my first storyboard and tried to set it as the main storyboard. After following the tutorial I clicked the run button and the simulator doesn't render any of the changes ive created.
I have a screen shot of my xcode project here(not sure how else to display it): https://app.box.com/s/okw7jlzq5zmcetd5cehu
What am I doing wrong?
Here is another screenshot of the storyboard itself: https://app.box.com/s/jt6i0an3maowwvgsamk7
Place a checkmark in the box "Is Initial View Controller" for the view controller you want to load.
I think your problem is the code in the app delegate. When you use a storyboard, you don't need anything in there except "return YES". The storyboard creates the window, so the code you have in there is making another window, not the one that your storyboard controller is a subview of.
Using this tutorial might teach you some things about the structure of an iOS app, but if you just want to make an app with a storyboard, you should start with the "single view" template instead of the "empty" one. It will give you a storyboard and an initial controller.
So I'm going to try to explain my issue as best I can.
I have 2 View Controllers on a Storyboard. One is the "main" VC and the second is a "EULA" VC.
The main view controller has a UIWebView which loads the primary UI and works fine. This controller uses code to perform a Modal segue to the EULA VC which is created in the interface builder. This also works fine.
Now here lies my problem. The EULA view controller also has a UIWebView on it but I can't seem to connect this view controller to any connection by means of CTRL + drag. The "main" UIWebView is connected to ViewController.h
This is how I create my connection with CTRL + drag:
My question is why am I able to connect the first UIWebView on the Main view controller but not the other UIWebView on the EULA view controller? What am I missing?
Have you set up the EULAViewController.h as the custom class for the ViewController in Interface builder? Select the UIViewContoller in Interface Builder and in the third tab make sure the class is correct. Here is a screenshot explaining what I am saying:
Also make sure you have selected the correct file in the right pane, both red boxes should show the name of your custom UIViewController subclass:
I am think this is a bug in XCode or what. But this is very rare issue. I also got this issue sometime. So posting a solution which can make you little nervous to implement. But it works for me sometimes. You can try it . -
Just create a new UIViewController subclass in your project and name it something slightly different than the first. Then, copy/paste all code from old non-working UIViewController into the new UIViewController subclass (.h and .m) and change all relevant symbols according to the new UIViewController subclass name. After doing this I found everything worked as normal in terms of trying to control-drag wiring the buttons.
Happy coding. :)
Recreating the class files, renaming the view to something else then back to EULAViewController AND following these steps I was able to fix the issue.
Close the project you are working on with.
Delete the【DerivedData】folder of you project. (This folder may
inside your project's folder, or inside
~/Library/Developer/XCode/DerivedData/(your project)/ ) or somewhere
else that were setup by you.
restart you project.
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'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.
