Learn to Code a Basic iPhone App - Lifehacker.
If your application needs to use the camera so a user can take a picture, there is no need to write the code for the camera because it already exists. All you need to do is start the activity for the camera application and your application will automatically have full control of the camera and any pictures that are recorded using the camera activity. This is great news for you because you can.
Then in Lesson 3 of this iOS app development tutorial, we'll learn how to write code in Apple's Objective-C programming language. Once we've gotten the hang of programming, we'll create three more apps as we explore Apple's iOS software development kit. I'll walk you through every detail of developing the apps from project creation, through every line of code, and on to testing the app.
Congratulation! You’ve built your first iPhone app. It’s a simple app however, I believe you already have a better idea about Xcode and how an app is developed. In the next post, I’ll further explain the Objective-C code we’ve done here and how the HelloWorld app actually works. Stay tuned.
In Coding iPhone Apps for Kids, you’ll learn how to use Swift to write programs, even if you’ve never programmed before. You’ll work in the Xcode playground, an interactive environment where you can play with your code and see the results of your work immediately! You’ll learn the fundamentals of programming too, like how to store data.

Now that the iPhone SDK has officially been released and the Apple App Store is open for business, it’s time to write killer mobile applications! To do that, you’ll need to use several powerful (and possibly unfamiliar) tools: Xcode, Interface Builder, Objective-C, and then the iPhone SDK itself. It can all be a little overwhelming at first.
The iOS SDK has made it really easy to send email using the built-in APIs. With a few line of codes, you can launch the same email interface as the stock Mail app that lets you compose an email. In this tutorial, we’ll build a very simple app to show you how to send both plain text and HTML email using the iOS SDK.
