iOS (iPhone, iPad) 

iOS is a mobile operating system developed and distributed by Apple Inc. It was originally released in 2007 for the iPhone, iPod Touch, and Apple TV. iOS is derived from OS X, with which it shares the Darwin foundation. iOS is Apple's mobile version of the OS X operating system used in Apple computers.

 INTRODUCTION

iOS, which was previously called iPhone OS, is a mobile operating system developed by Apple Inc. Its first release was in 2007, which included iPhone and iPod Touch. iPad (1st Generation) was released in April 2010 and iPad Mini was released in November 2012. The iOS devices get evolved quite frequently and from experience, we find that at least one version of iPhone and iPad is launched every year. Now, we have iphone5 launched which has its predecessors starting from iPhone, iPhone 3gs, iPhone 4, iPhone 4s. Similarly, iPad has evolved from iPad (1st Generation) to iPad (4th Generation) and an additional iPad Mini version. The iOS SDK has evolved from 1.0 to 6.0. iOS 6.0, the latest SDK is the only officially supported version in Xcode 4.5 and higher. We have a rich Apple documentation and we can find which methods and libraries can be used based on our deployment target. In the current version of Xcode, we’ll be able to choose between deployment targets of iOS 4.3, 5.0 and 6.0. The power of iOS can be felt with some of the following features provided as a part of the device. 

 Maps 

 Siri 

 Facebook and Twitter 

 Multi-Touch  Accelerometer 

 GPS 

 High end processor 

 Camera 

 Safari 

 Powerful APIs 

 Game center 

 In-App Purchase 

 Reminders

  Wide Range of gestures 

The number of users using iPhone/iPad has increased a great deal. This creates the opportunity for developers to make money by creating applications for iPhone and iPad the Apple's App Store.

Registering as an Apple Developer

An Apple ID is most necessary if you are having any Apple device and being a developer, you definitely need it. It's free and hence, no issues in having one. The benefits of having an Apple account are as follows:

      Access to development tools. 

      Worldwide Developers Conference (WWDC) videos. 

      Can join iOS developer program teams when invited. 

To register an Apple account, follow the steps given below: 

1. Click the link (https://developer.apple.com/programs/register/) and select "Create Apple ID".

2. Provide the necessary information, which is self explanatory as given in the page. 

3. Verify your account with your email verification and the account becomes active.

4. Now you will be able to download the developer tools like Xcode, which is packaged with iOS simulator and iOS SDK, and other developer resources.

iOS –Xcode Installation

1.Download the latest version of Xcode from (https://developer.apple.com/downloads/)

2. Double click the Xcode dmg file. 

3. You will find a device mounted and opened.

4. There will be two items in the window that's displayed namely, Xcode application and the Application folder's shortcut.

 5. Drag the Xcode to application and it will be copied to your applications. 

6. Now Xcode will be available as a part of other applications from which you can select and run. You also have another option of downloading Xcode from the Mac App store and then install following the step-by-step procedure given on the screen.

iOS ─ First iPhone Application

Now we are going to create a simple single view application(a blank app) that will run on the iOS simulator. 

The steps are as follows. 

1. Open Xcode and select Create a new Xcode project.

2. Select Single View Application.

3. Enter the product name, i.e., the name of the application, organization name, and then the company identifier.

4. Ensure that Use Automatic Reference Counting is selected in order to automatically release the resources allocated once it goes out of scope. Click Next.

5. Select the directory for the project and select create.

6. You will see a screen as follows: 

In the screen above, you will be able to select the supported orientations, build and release settings. There is a field deployment target, the device version from which we want to support, lets select 4.3, which is the minimum deployment target allowed now. For now, these are not required and let's focus on running the application.

7. Now, select iPhone simulator in the drop down near Run button and select run

8. That's it; you have successfully run your first application. You will get an output as follows

Now let's change the background color, just to have a start with the interface builder. Select ViewController.xib. Select background option in the right side, change the color and run.
