Getting Started with iPhone Development

Introduction:

Many peoples start working with iPhone without knowing many things about it and later they find it difficult to get everything on board. So this tutorial is focused on getting “Hello World” application running on iPhone simulator. I have also created a screen cast of this. If you do not like to read these 10 steps , you can simply move to video tutorial page.

10 Steps to create your hello world iPhone tutorial

You need following things before you start developing your hello world application in simulator:

  1. A MAC machine
    • Specification of that machine is, it should have Intel processor with 10.5.7 or latest Leopard installed.
  2. Apple Developer Account ( which is free for everyone , you can register your self here)

To get start with iPhone development you need to have iPhone SDK . To test the code on your device (iPhone) you need to buy a developer license which cost you 99$ or 299$ for enterprise.

You have to follow these steps to get your first hello world application running on iPhone simulator. So this is your first hello world iPhone tutorial to get everything on your machine before you start developing big iPhone applications.

Step 1: After downloading the sdk and updating your mac os x to 10.5.7 leopard or above, you can install the sdk. If your mac is not updated to 10.5.7 at-least, you can install the xcode but not iphone development kit. (Look at 3rd picture, iPhone SDK check box should be enabled and bold)

    Thank you for this – it’s so good to see something for my level :D
    I’m eager to start developing for iPhone and this is going to help me do it.

    Hey, appreciating the tutorials! thanks alot!
    i have a endless list of tutorials to request but ill just start with the one :]

    what i would really like you to do is a tutorial on a user editable UIPicker in a sub view.
    iv been looking every where and theres nothing clear enough to work from! and i say in a sub view because all tutorials on making the UIPicker in its self are for the mainView and use the appDelegate which ( being new to developing) makes it alot harder to follow when using it in a realistic app.
    i eventually did figure it out using sample code but i bet alot of new developers would appreciate a straight forward tutorial!

    so to sum up, my request is for a user editable UIPicker. Like How a UITable can have text added and deleted.

    hope you can get around to doing this :] thanks

    Youre iPhone Development tutorials are great!

    Can you make a tutorial for a tableview app that have a springboard menu on the start of the app.
    ( 16 icon’s menu at the start, 4 rows and the 16 cells)

    icon 1 | icon 2 | icon 3 | icon 4 |
    icon 5 | icon 6 | icon 7 | icon 8 |
    icon 9 | icon 10 | icon 11 | icon 12 |
    icon 13 | icon 14 | icon 15 | icon 16 |

    click on a icon and you get a tableview.

    There no tutorial on the internet about this…

    Best Regards,
    Alwinkov

  4. Thanks for these tutorials, but they are a bit out of date with the advent of the new SDK. You might update them with the new screens soon, since there are more and more of us new developers that need to see these tutorials in the new environment, since its rather drastically different.

    Thanks.
