8. www.folio3.com 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.

10. www.folio3.com IOS Architecture

11. www.folio3.com 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

12. www.folio3.com 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

13. www.folio3.com Cocoa Touch Layer Frameworks UIKit Framework Map Kit Framework Push Notification Service Message UI Framework Address Book UI Framework GameKit Framework

14. www.folio3.com 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.

15. www.folio3.com 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,A udioUnit.framework)  Open Audio Library(OpenAL)  Media Player Framework (MediaPlayer.framework)

16. www.folio3.com 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

17. www.folio3.com 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.

18. www.folio3.com Core OS Layer Frameworks  CFNetwork Framework(CFNetwork.framework)  External Accessory Framework(ExternalAccessory.framework)  Security Framework (Security.framework)  System(LibSystem)

20. www.folio3.com 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 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.

23. www.folio3.com Creating Sample Hello World App Step-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

24. www.folio3.com Xcode Startup Screen

25. www.folio3.com Creating Sample Hello World App Step-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

27. Creating Sample Hello World App Step-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
