at the moment I try myself on iphone develpment.
I read a lot of howtos and a complete book, to find myself in ObjC.
I can create my first app, hello world, get actions on buttons and so on.
Now I have my View (Created on New Project -> View Based App).
How can I create a second View and show the second view on a button click on a first view?

Hello fellow StackOverflowers, I am in a bit of a dilemma with trying to condense the code in my application, iEngineering, that is available for free on the AppStore. Please download it so you can follow along with the rest of this post.
Alright, so when creating the current version of iEngineering, I used a new UIViewController with a UITableView for every "new" screen for all of the listing (table view) screens. The one story board file I am using currently has ~100 view controllers, takes 10 minutes to load, and several minutes to load the simulator. Big, big rookie mistake.
I am currently in progress in developing a plan to condense all of the UITableViewControllers into a single reusuable UITableViewController if it's feasible. However, I am running into trouble in figuring out what topics I should research to learn out how to refresh/present an updated listing (table view) in the view controller if you segue/transition to a subdirectory screen of the app. For example, selecting "Chemical Engineering" in the home screen and transitioning to the next listing screen that displays the following: "General Chemistry, Fluid Mechanics, Reactor Design, Separations, and Thermodynamics."
Would this be a reasonable/feasible task to condense down my current project? If so, what topics should I research to figure out how to do the transitioning/updating to a new table view screen?
In the images below, I am trying to condense the view controllers into only a couple of view controllers (Note: The image doesnt display the 80+ view controllers off the screen. xCode wouldn't zoom out anymore.)
I am making a basic application in opengles, and I started with "raywenderlich" Glkit tutorial. This displays a cube in the starting screen of the app. And he mentioned the below lines in his tutorial to do this.
To make this Storyboard run on startup, open HelloGLKit-Info.plist,
control-click in the blank area, and select Add Row. From the dropdown
select Main storyboard file base name, and enter MainStoryboard.
My questions:
1) I need to add a view before starting the the GLKIT view. How can I do this? From that UIview I need to change over to GLkit view? How to do this?
2) I need to access the values I used in previous UIviews, say "x=10,y=20" in GLkit view.
This is typical iOS beginner tutorial material, have a look at this and if it doesn't suit your needs, their are tons of other tutorials out there. the task is quite laborious to explain, but it is simple so dont worry.
I am very new to iPhone development, i am developing one sample application using xcode.
I am referring on-line tutorials and examples to build my first application.
I want to try multi screen/view application where i want to display specific screens on some specific events like button clicks.
I googled for tutorials on multi screen iPhone apps, but i am getting different ways of doing it.
I am confused in-between:
1. Navigation based application.
2. Window based application.
3. View based application.
Which application type do i need to chose for multi view/screen application. Is it that we can't create multi view/screen application using 2nd and 3rd type, i think this should not be the case, but i am confused.
what i have done so far.
I have created one window based application where i have one login page (text fields and click buttons) i want to extend this application to display main screen/error screen based on the login result.
I have created 2 .xib files for main screen and error screen(with there corresponding .m and .h controller files), now i want to remove login screen and display main screen/error screen, but i don't have idea how to archive this when we are in window based application.
can some one point to useful tutorials/examples that can explain this scenario.
Before getting into any online tutorials it'd be better to go through apple's guides.
Following guides could be a good start:
App Programming Guide - Design Basics To understand the basics of iOS development
Human Interface Guidelines
and
View Programming Guide
To understand and implement different view controllers
hope this helps your question regarding delegation

If you're using storyboards with scenes and segues (iOS 5+), this tutorial might help clear things out.
I am a beginner to the iOS app development and working on a sample app that consists of just two "screens" - the first screen authenticates the user against user id and password saved in a SQLite database table and the second screen displays list of users in the database if user authentication is successful. If authentication fails I would just like an alert displaying appropriate message to the user.
I somehow can not connect how to "go to the second screen" if user authentication is successful. How can I tell the application that now that the user is authenticated it is time to go to the second screen and display the list of users?
I apologize if the terminology I use is not standard iOS app development terminology but I am new and would like to fill the gaps in my understanding. Please feel free to direct me to any links/tutorials/documentation.
Thank you.
Navigation is a fundamental and essential part of iOS programming and UX design. Traditionally, views are managed by ViewControllers, which in turn may be managed by NavigationControllers in stacks. To naivgate between and away from controllers, we define two new verbs: Push and Pop. To go to a new view, one pushes it onto the navigation stack. To transition away from a view, one pops it off the stack. And so, with these two paradigms, we can define simple transitions which are managed by the UINavigationController object. Have a look at the navigation guide in the docs before you proceed any further.
You don't appear to have sufficient understanding of iOS basics for any of our answers to be helpful. A word of advice: don't waste your time wrestling with code before you have a bit more of a foundation; you will just become frustrated.
Take a few hours and review some of the videos in Paul Haggarty's Standford iOS course.
Once you understand some of the building blocks and concepts of the API, things will move along much more quickly.
Are you developing against iOS with Storyboards?
If you start with the boilerplate "Master/Detail" template in Xcode for iOS 5 with Storyboards, you will get some sample code for a master view (uses a UITableView), detail view (uses a UIView with a label in it), and a segue between the two view controllers to go from master to detail, along with a "Back" navigation button that pops the detail view off and back to the master view.
The iPad boilerplate for that type of project is slightly different in the it uses a UISplitViewController to show both master and detail at the same time and doesn't use a segue between the two.
You could take a look at that boilerplate code, modify it, and go from there.

Hii...all
I am new to the iPhone application development. I am trying to develop one image slider type application using xcode 4.2
can anyone let me know which template should I use i.e. single view application,Tabbed application , or page based application or any other .. ??
n please also let me know how to use a page controller in the application n how to add new view to display an image in the next view of the application using page controller.
thanks in advance...
Fist: As you are new to iOS, start with an empty application. You can learn the most by this.
Second: Read some introduction stuff.
Third: I would recommend for your needs to use a scroll view and load the pictures as they are needed. You can find a video showing how to do this in the developer portals in the WWDC videos (payed account needed).
