I received lots tutorial requests from my readers that asked to me, how to start iPhone and iOS application development. We are planning to write a iPhone and iOS application development tutorial series for this you need a Mac iOS and Xcode IDE. Just follow these steps and you can create a simple “Hello World” program.

Step 6
Project property windows contains appdelegate files and other supporting files. We need to create a screen/class with xib(user interface). Right click on the project folder and select new file as shown in the below image.

Step 10
Home screen has been successfully created and it will look like below image.

Now open homescreen.h file and create a UIButtonField with its onclick function programmatically with the below mentioned code.

@interface homescreen : UIViewController
IBOutlet UIButton *btn_hello;

@property(nonatomic, retain)IBOutlet UIButton *btn_hello;



Now your homescreen.h file will look like this

Now open homescreen.m file and synthesize your button field at top and add a alert box in the button click function as shown below
@synthesize btn_hello;

UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Success !!!"
message:@"Hello iPhone"
delegate:self cancelButtonTitle:@"OK"
[alertView show];
[alertView release];

The memory allocated by the button has to be released manually as shown below
- (void)dealloc
[btn_hello release];
[super dealloc];

So your homescreen.m file will look like the below shown image

Step 11
Now it’s time for design part. Open the homescreen.xib file and drag a button in the right side object window and drop it in the view controller.

So design part is over. Now your application is ready. But, the problem is this is an empty application. Application don’t know where to start. So we need to redirect the application to the home screen.
Open Appdelegate.h file and declare UINavigationController as shown below

@interface AppDelegate : UIResponder <UIApplicationDelegate>
UINavigationController *navigationController;

@property(strong,nonatomic)UINavigationController *navigationController;

@property (strong, nonatomic) UIWindow *window;


Your Appdelegate.h file will look like this

Getting Started with Iphone

Step 16
Now open AppDelegate.m file and mention the homescreen to be the start point of the application as shown below
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
UIViewController *homeController = [[homescreen alloc] initWithNibName:@"homescreen" bundle:nil];
navigationController = [[UINavigationController alloc] initWithRootViewController:homeController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;

Step 17
Your AppDelegate.m file will look like below image. Now it’s done. Click on the run icon on the top left corner as shown in below image.

Step 18
It will take few min to open the iphone simulator and your project. Your application will look like below image

And if any one like me won't have MAC then he can simply use Phone GAP which is cool and works awesome, supports many platforms and the best part you can also use Web application programming languages like Javascript for giving it action, CSS for making the UI and HTML for making objects.
http://phonegap.com/ and for tutorials about Phone GAP you can simply see the documentation, if you know Javascript CSS and HTML then just the way how to use the IDE and everything you will learn automatically!!
