How to start working with Xcode - xcode

I am developing an iPhone Native App. So can any tell me how to start working with Xcode? I have created Hello world program. My requirement is "I am having 2 drop down list and a button, where both the drop down list are fetching data from DB." I tried searching for drop down list in Interface Builder but unable to find it. Can anyone guide me how can I proceed for this?
Thanks in advance.

There's no such thing as a "drop down list" with the default interface elements in iOS. You'll either want to use a UIPickerView or a UITableView, depending on your application.
The easiest way to get started with UITableView is to use Xcode to create a new Navigation-Based app with Core Data for storage. This will setup most of the basic stuff for you and you can either tweak it to suit your needs or you can just see how the interface and data elements interact with each other.

Xcode 6 - Swift - Multiple views on a single-window storyboard cocoa app

Just last week I decided to dive into the world of Swift and Xcode development, and as of yesterday I am actively working on a new application. I have a lot of experience with Java Swing, but working with that is obviously a lot different than working with Apple's fancy interface builders and storyboards.
I am trying to develop a single-window application that has many different views that can be navigated by buttons. I tried to wrap my head around the way the storyboard works, but even after all my reading of the documentation I don't know really what I'm doing - I'm so used to working in hard code. It came to the point where I wrote my app's entire network layer just to avoid working with the interface.
Basically I have a set of different NSViewControllers, each with references to a few of their components (buttons, labels, etc) and I want certain buttons to be able to change the current view controller (preferably with a segue animation) to a different one. How can I approach this? I would guess that this isn't hard to achieve, but I am lost. Any help would be appreciated!
Let me know if I need to submit any code - I do have the basic classes written but nothing relating to this.
Thanks,
-Aidan

Xcode 4.2 and new Tabbed Application Project

Can anyone help with Xcode 4.2 and the new tabbed application project? With Xcode 4.2, i create a new tabbed bar application, and it works as desired. However, it seems that instead of creating a new window and main.xib file that contains the tabviewcontroller, it sets everything in code within the appDelegate.
its easy to work with the tabbarcontroller via code and i have no problems setting up other tab items, however, i feel that my iOS development skills (they are new) are missing something as i would NOT even know if it was still possible to work with the tabviewcontroller graphically now in the way this project template has been setup.
Is there a way to work with the tabviewcontroller graphically? would i have to create a new main.xib file and link everything up to that? i'm still not strong enough in my skills to work out all the minute details but if that is the path that people suggest, i will look into it and try to figure it out.
I only want to work this out so i can fully understand whats going on now with Xcode 4.2, I have no unrelenting desire to only work with the tab bar controller graphically, but am curios as to why i cannot find it (or if i should)... just trying to get my head around how these things should be working.
You should use the Single-View Application template.
HEre you can add graphically that control

How Do I Connect A UITabBarController To The App Delegate In A View-Based App (Part 1)?

I'm attempting to convert my view based application to a tab bar application. I'm having trouble connecting a new UITabBarController to the App Delegate. It doesn't give me the option. I must be missing some sort of connection along the way.
I added a Tab Bar Controller to my "MainViewController.xib". From most of the things I've read, I should be connecting to the "MainWindow.xib," only problem is that I've got both iPhone and iPad formats setup from the View-Based Application so I'm looking for a way to connect it universally (so I don't have to recreate it for both the iPhone and iPad formats separately).
I created an outlet in my MillersAppAppDelegate.h file (and synthesized it all correctly) but the outlet that I created for the Tab Bar Controller does not appear as an option when I attempt to connect it in the Interface Builder (I'm assuming this is because I haven't correctly connecting the Tab Bar Controller to the delegate in the first place).
I'd like to just stop here and learn this first step so it doesn't get too confusing yet:
1) How do I connect my new Tab Bar Controller to the App Delegate in a View-Based App?
2) How do I then subsequently connect my Tab Bar Controller (that was created and synthesized in the App Delegate) to the UITabBarController?
I've looked at other people's questions regarding this type of thing and most of the reactions are "It's easier to just start a new tab bar app and transfer the content over." I still want to be able to learn how to do this though, it'll help me learn the language of X Code and Objective C better by pushing through it and make me well versed and better in the end (as it will for the others with similar questions). Thanks for putting up with my beginner questions, I'm still learning!

Xcode 4.2: What is the most effective method switching views?

I was thinking of games in particular, where there may be alot of views that need to be switched in and out. Could someone supply some sample xcode 4.2 code? Many tutorials have old xcode versions which have different initial code.
Thanks
Most efficient method I would say is usin the story board feature. Set up a new view controller inside the main storyboard file and then control drag from which red button on one view to the next one. Very easy and no code required. Email me if you had any problems dai.evans94#live.co.uk

Drop down menu like the default iPad application menus

I'm currently working on my first iOS application to run on the iPad, and I've come across a problem. I have been asked to implement menu's similar to the ones in the default applications such as when you click on the "Calendars" button in the top left of the calendars app.
Only issue is, I cant seem to find a standard UI object that looks like these, with the arrow connecting the menu to the button etc. Is this a standard UI component that I should be able to use, or will I have to imitate them by creating a custom object?
Thanks for any help.
That is a UIPopoverController. There isn't an Interface Builder control for this. You need to create one programmatically:
UIPopoverController *popover = [[UIPopoverController alloc]initWithContentViewController:someTableViewController];
See the documentation for more information and sample projects, specifically ToolbarSearch:
