I am unsure of how to link three Views (1 table view, one view that adds data to the table view through core data and one camera view) to the one view controller each with individual buttons.
I've tried to search to find a tutorial for linking views through the storyboard but have found none that help.
If I could have some instructions on to how I can do this (through code or storyboard) that would be much appreciated.
So if I understood it right, you wanna connect three buttons in your storyboard to open different views in storyboard. If yes, you can use this approach: Xcode 4 UIButton segue push to Table View Controller

I am developing a new iPad application . I end up with multiple master as well as multiple detail.
I searched the stackoverflow and found the same article : iOS - UISplitViewController with storyboard - multiple master views and multiple detail views
Since I am a new user, I can not comment on the same article.
My question is where should I put the UISplitViewController in storyboard?
As per the above article , "(1)Navigation Controller -> (2) table view of 6 menu options -> (3) Each cell in the table pushes a different table view controller onto the navigation stack."
should I put split view controller here before (3) or it will go somewhere else?
I am new to ios development, any help will be appreciated.
Please refer following link:
uisplitviewcontroller
From my experience, you should place split view controller at first place, as master detail are going to embedded in UINavigationController.
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.
This is my scenario: I have an app with TabBar and NavigationController using storyboard. TabBar has item A and item B, both an identical UITableViewController and cells prototypes, it only fetch the info from different locations.
How can I identify from which UIStoryBoardSegue it came? Or there is a better way to do this (maybe duplicate Xib and UIViewController)?
Here a picture of my UIStoryBoard:
I was recently working on a project with the same structure and I added two tableviews. But i think it's possible to have one tableview with two different source views. You can try using a navigation controller and when you push to the table view the "back" button will bring you back to the origin.
Seems strange to have two Navigation Controllers pointing to the same Table View. Why don't you just copy the Table View in the Story Board and use the same class?
In Xcode, how can I create a simple iPad application that uses Storyboards such that the DetailView controller is swapped out for each entry? Most examples that I've seen use the iPhone or they simply change the values in the same detail view controller.
I want to create the segues in Interface Builder from a static TableView Controller (with say 3 rows) where each row will load a different game detail view controller, which I would drag out and design in IB. Currently, when I connect a view controller with a segue, it replaces the navigation part of the UISplitViewController. In other words, it's like I'm traversing a tree, and I need to tell IB that I'm at a root node and I should be changing the Detail View.
A good starting point for segues are Lectures 6 and 7 of Stanford's CS193p Fall 2011 class.
http://itunes.apple.com/us/itunes-u/ipad-iphone-application-development/id473757255
The instructor, Paul Hegarty, covers everything. However, he runs out of time before the end of class to answer this question. He does include the source with the final solution in the file: Psychologist with Dr Pill.zip.

Basically, all that needs to be done for this question is to Ctrl-drag from each UITableCell to the respective game detail view controllers then select the Replace segue. There is one more step because the view controller will shrink because by default Xcode thinks that you want to replace the master controller. For each of the segues, select the connection line and in the Attributes inspector then change the Destination from "Master Split" to "Detail Split". At this point, you can test with the popover, without writing any code.
Apple has provided sample code of a more general solution to the problem of how to swap out different detail views based on what is selected in the master view. The Apple example code accomplishes this by introducing a custom implementation of the UISplitViewControllerDelegate protocol:
https://developer.apple.com/library/ios/samplecode/MultipleDetailViews/Introduction/Intro.html
Hard to describe without pictures but: have a navigation controller as the master. Then hang each detailview off this with a named segue that replaces.
Then you need a bit of code.
In you master viewcontroller inside didSelectRowAtIndexPath, you need a switch statement based on indexpath.row and in each row call detailview performSegueWithIdentifier:#"the row you want"
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?
