created a singleview application with storyboard.
Added three viewcontrollers apart from the one view present by default,Now how to refer to this ViewController programmatically from the AppDelegate did finishlaunchingoptions function? I've created 3 view controller classes and what are the changes i should do in appdelegate
Well it seems as if a tutorial would make sense so you could learn how storyboard based development in iOS 5 works.
A great one i found is this one written by Ray Wenderlich.

I would like to implement a layered viewcontroller control, where pushed viewcontroller doesn't cover the entire screen but will leave say 20pixela width on the left. If 5 viewcontrollers are pushed and I'm tapping on viewcontroller 2, it should expand, but not remove viewcontroller 3,4 and 5. Only slide them to the right.
The idea comes from the iPad app Trivago and I don't know if they're using an open framework. If not, do you guys have a good idea for implementation? The structure/architecture is fine :-)
If I can create a nice control I will make it public as a cocoapod :-)
Thanks!
Sounds like you may want to do View Controller Containment instead of using a UINavigationController.
See: Creating Custom Container View Controllers
Update:
More examples:

All the examples I've seen for PageControl has used XIBs to switch between views when you scroll. Is this a requirement? Is it possible to load another viewController in Storyboard for the PageControl? I tried doing it, but no success. It does not load the ViewController. I was told to use initWithCoder to load Views from the Storyboard. I have no idea what to put in the initWithCoder and the documentation on Apple Dev on initWithCoder and Coders are confusing.
I could only get paging to work with XIBs.
Update:
So more specifically, the paging works fine, but I am asking when I make a ViewController class that manages one of the paged Views. How do I get the class to load the View from Storyboard? I could only get the view to load when using a XIB.
Thanks,

I created an empty iPad TabBar application using XCode 4, without storyboards. I placed that app in a workspace. I then added the Kal source (obtained from the iPad Juice build) to the workspace as a separate project. The initial build was clean.
I then went to the Kal example (NativeKal) and added EventKitDataSource.h and .m, and NativeCalAppDelegate.h and .m. (The image below shows what files are in the example project)
This is the code from the NativeCalAppDelegate.h file:
I tried setting the first TabBar UIView controller to "KalViewController" as I would normally do when using Storyboards, but it isn't listed in the drop down list of classes.
The question is: how do I get the NativeCal example view controller to replace FirstViewController in the in my TabBar application?
Comments added as Answer.
My recommendation is to switch to storyboards it is a lot easier to do UITabBarControllers in them. You can do this by just creating a new storyboard and copy and paste everything into it and then control drag from the UITabBarController to the UIViewControllers that you want to be linked to the tab bar controller and it does the rest for you, everything else is the same after that. In storyboards you can set the first view controller to be loaded so if you need it to be KalController then you can set it when you set up the UITabBarController. You can also set this in the code. I found that storyboards were a great new feature to xcode, UITabBarCotrollers are a lot easier to do in them then in .nib files I could never get them to work.
Hope this has helped.
I have been learning iOS development for a few days now. At this moment, I have questions over how the rootViewController is to be used. I searched the web for 3 hours yesterday looking for the answer which turned up quite a few results that never really answered my question.
I am trying to learn to program an app using code only (no storyboards/xib files). I currently am trying to understand how to properly switch between views without using the UINavigationController. In my project I have the main delegate which creates the window, initializes my main view controller (which loads the separate view as well) and adds it as the rootViewController.
My first view has a button which calls a function in its controller to switch to my next view. Here is where my question arises: Do I switch the main rootViewController to the next view or do I load the next view as a subview of the rootViewController? Is the rootViewController supposed to encase all the views for an application? (I think this is how the UINavigationController works)
I have gotten switching of the rootViewController to work in my app, but I want to make sure there isn't some other way I am suppose to manage my views.
I would not switch the rootViewController, I think that should remain stable. So you could add it as a subview, or you can present it as a modal view.
And of course, you can just change the rootViewController to point to your new view if that's how you want to do it.
I have basic *.xib file, which have NSView.
How can I use another nib files for this Custom View? What is NSViewController and how should I use it?
Generally, you create a new nib, selecting "View" as the nib template. Then you select the File's Owner and set its class to NSViewController (or your own subclass of it, in which case you may have to add the nib to your Xcode project first) in the last tab of the Inspector. Then you connect the view controller's "view" outlet to the view.
You should read Apple's docs on NSViewController, it's actually a very simple class. However, before you start drawing and coding I would suggest you should carefully structure your app in MVC terms. If you make a mistake in the design phase, you will have to redo a lot of your work later. Using view controllers is not always justified, it depends on the complexity of the app.
NSViewController as its name suggests is a Controller class, means it connects the View to the Model, in a perfect MVC environment.
Each ViewController is bound to one View, you can build that view in code or using the Interface Builder.
For more help, I would suggest to watch Stanford University iPhone programming course, it's available on Stanford iTunes (iTunes link), iPhone SDK share the same underground with the OSX SDK so it's exactly the same for ViewControllers.
