• Session 1– Iphone development Types– Brief Overview of deployment Strategies– Iphone OS Architecture

• Session 2– Iphone App Testing

• Session 3– Objective-C Intro

• Session 4– The Cocoa Foundation Kit– Graphical User Interface– Windows, Views and Controls.


IPhone Development Types

There are three development types of Iphone Apps:

• Web based appWeb based app running in Iphone safari browser.

• IPhone Native appsIPhone Native apps running natively.• 33rdrd party development platform party development platform that

generate native apps.


IPhone web apps development

Below are the system requirement for it:• Mac machine is not necessaryMac machine is not necessary. Any OS/hardware can

be used for it.• Aptana Studio IDEAptana Studio IDE is used for Iphone web app

developments.


IPhone Native App development

Below are the System requirements for IPhone native app development:

• Mac MachineMac Machine• XcodeXcode (IDE for developing native

Iphone/IPad app as well as Mac apps).• Iphone SDKIphone SDK. The latest one is 4.3.• Iphone Developer accountIphone Developer account for getting

developer profile certificate to install app on real iphone device.


3rd party Native Iphone App Development Solution Available in market• MonoTouch• Rhomobile(write once run anywhere)• Appcelerator (write once run anywhere)


App distribution strategies

Adhoc distributionApp Store distributionEnterprise distribution through local app store


Iphone OS Architecture

– Its similar to the basic architecture of Mac OSX

– IOS acts as an intermediary layer b/w the underlying hardware and the application that appears on the screen

– Application that we create never interact with the hardware instead with the iOS.


MacOSX architecture


IOS Architecture


IOS Architecture

In practice, an app can directly call any of the layers of the stack to perform tasks on the device.

Each operating system layer provides an increasing level of abstraction away from the complexity of working with the hardware.

One should, therefore, always look for solutions located in the higher level OS layers before writing code that reaches down to the lower level layers


Cocoa Touch Layer

Sits at the top of the iPhone OS stack Contains the frameworks that are most commonly used by iPhone application developers. Written in objective-C and based on Mac OSX Cocoa API


Cocoa Touch Layer Frameworks

UIKit FrameworkMap Kit FrameworkPush Notification ServiceMessage UI FrameworkAddress Book UI FrameworkGameKit Framework


Media Layer

Media Layer provide the iPhone OS with : audio, video, animation and graphics capabilities

Media layer comprises a number of frameworks that can be utilized when developing iPhone apps.


Media Layer Frameworks

Core Graphics Framework(CoreGraphics.framework)

Quartz Core Framework(QuartzCore.framework) OpenGL ES Framework (OpenGLES.framework) AV Foundation Framework

(AVFoundation.framework) Core Audio Frameworks

(CoreAudio.framework,AudioToolbox.framework,AudioUnit.framework)

Open Audio Library(OpenAL) Media Player Framework

(MediaPlayer.framework)


Core Services Layer

provides much of the foundation on which the above layers are built.

Consist of below frameworks: Address Book Framework

(AddressBook.framework) Core Data Framework(CoreData.framework) Core Foundation

Framework(coreFoundation.framework) Foundation Framework (Foundation.framework) Core Location

Framework(CoreLocation.framework) Store Kit Framework(StoreKit.framework) SQLite Library


Core OS Layer

The Core OS Layer is the bottom layer of the iPhone OS stack and sits directly on top of the device hardware.

The layer provides a variety of services including low level networking, access to external accessories and the usual fundamental operating system services such as memory management, file system handling and threads.


Core OS Layer Frameworks

CFNetwork Framework(CFNetwork.framework)

External Accessory Framework(ExternalAccessory.framework)

Security Framework (Security.framework) System(LibSystem)


Iphone Development Tools


Xcode

– Xcode is an integrated development environment.

– Xcode can manage all your testing devices.– Apple makes xcode and distribute it for free.

You can get it from Apple's developer website:

– http://developer.apple.com/tools/xcode– Xcode is free but Apple wants you to get

register as a new developer and wants your name and email address.

Creating Sample Hello World AppStep-1 Starting Xcode

Where I can find xcode after installation? Macintosh HD -> Developer -> Applications -

> Xcode. After starting Xcode if you do not see the

welcome screen then go to Help -> Welcome to Xcode menu option to

display it


Xcode Startup Screen


Creating Sample Hello World AppStep-2 Creating New Project

From within this window click on the option to Create a new Xcode project.

This will display the New Project window where we are able to select a template matching the type of project we want to develop


Creating Sample Hello World AppStep-3 Choosing Project Template

There are about 6 project templates available to choose for any iphone project:

View-based Application Navigation-based Application Tab Bar Application Window-based Application Utility Application Open GL ES Application
