  • Apple iOS February 16 2012
  • Mobile Operating Systemo Initially released in june 2007o Programmed in C ,C++ and objective Co Derived from Mac os Xo Available in 34 languages worldwideo Developed for iPhone and extended to iPod Touch and iPado The Kernel Type is Hybrid Kernel Architecture
  • The iOS ArchitectureSimilar to basic architecture found in Mac OS X Acts intermediate between applications and hardware iOS Apps Hardware
  • The Layers in iOS Architecture Technology Consists of four Abstraction layers • Core OS Layer • Core service Layer • The Media Layer • The Cocoa Touch LayerUses Darwin foundation and therefore a unix like OS The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures.
  • The core of iOSContains the low-level features such as Accelerate Framework (Accelerate.framework) This framework contains interfaces for performing DSP, linear algebra, and image-processing calculations Core Bluetooth (CoreBluetooth.framework) This framework allows developers to interact specifically with Bluetooth Low-Energy ("LE") accessories External Accessory Framework (ExternalAccessory.framework) This framework provides support for communicating with hardware accessories attached to an iOS based device
  • Core services LayerContains the High-level features that all applications use such as iCloud Storage lets your application write data to a central location and access those items from all user’s computers and iOS devices Core services framework Includes Accounts.framework, AddressBook.framework and CoreData.framework for user accounts ,contacts and for managing model-view-controller application iCloud
  • Media LayerThe Media layer contains the graphics, audio, and video technologies Graphics Technologies Includes Core Graphics , Core Animation and OpenGL technologies which handles 2D vector and animating views and 2D and 3D figures Audio Technologies Supports rich audio experince and audio formats like AAC, Apple Lossless(ALAC),A-Law and Linear PCM Video technologies The iOS support the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions
  • Compression standards in Video Technologies● H.264 video, up to 1.5 Mbps, 640x480 pixels, 30 frames per second• H.264 video, up to 768 Kbps, 320x240 pixels, 30 frames per second• MPEG-4 video, up to 2.5 Mbps, 640x480 pixels, 30 frames per secondMedia layer also consists of different frameworks likeCoreAudio.framework, CoreImage.framework andCoreText.framework
  • Cocoa Touch LayerThe Cocoa Touch layer contains the key frameworks for building iOSapplicationsThe layer defines the basic application andsupport for key technologies such asmultitasking, touch-based input,pushnotifications, and many high-level systemservicesCocoa Touch follows a Model-View-Controller (MVC) software architecture
  • The iOS DevelopmentThe iOS SDK (Software Development kit) Includes interfaces,tools and resources Includes special packages called Frameworks A framework is a directory that contains a dynamic shared library and the resources (such as header files, images, helper applications, and so on)Key Components of SDK  Xcode Tools  Xcode  Instruments  iOS simulator  iOS Developer Library
  • Xcode Tools• Xcode is a suite of tools used for developing softwares for Mac OS X and iOS• An Integrated Development Environment (IDE) that manages to edit,compile,run and Debug source code• Xcode suite supports C, C++, Objective C, Objective C++, Java, AppleScript, Python and Ruby source code with a variety of programming models• Instruments are the runtime performance analysis and debugging Tools• iOS Simulator is a Mac OS X application that simulates the iOS technology stack, allowing you to test iOS applications on Macintosh computer
  • Xcode Version series  1.x series  2.X series  3.x series  4.x seriesThe latest stable release is Xcode version 4.2.1, which is availableon the Mac App Store
  • iOS Distribution
  • iOS Version HistoryOn June 29, 2007, Apple released the first version of iOS  iOS 1.x: initial OS  iOS 2.x: second major OS  iOS 3.x: third major OS  iOS 4.x: fourth major OS  iOS 5.x: fifth major OSThe Latest Stable release is version 5.0.1 (Build 9A406) for iPhone 4 SThe Latest Stable release is version 5.0.1(Build 9A405) for iPhone,iPhone 3G,iPhone 3GS ,iPhone 4,iPod Touch and iPadThe Latest unstable release is version 5.1(Build 9B5141a)

  • ConclusionThe objective of the seminar was to study and enhance our knowledge about Apple iOS , mobile operating system. We have learnt about the new features of the iOS 5 operating system. So we have learnt about the layers of iOS technology viz. core OS, core services, media and cocoa touch. The fact that all the information regarding iOS cannot be bound in this Presentation, I have tried to cover almost all points that made study of iOS worthy.
