  4. 4. General Overview • 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. Swapnali Pawar
  5. 5. Features of iOS operating System: 1. Highly Securer than other operating systems. 2. iOS provides multitasking features like while working in one application we can switch to another application easily. 3. iOS’s user interface includes multiple gestures like swipe, tap, pinch, Reverse pinch. 4. iBooks, iStore, iTunes, Game Center, and Email are user-friendly. 5. It provides Safari as a default Web Browser. 6. It has a powerful API and a Camera. 7. It has deep hardware and software integration Swapnali Pawar

  10. 10. Similarities Between iOS and Android •The basic functions in iOS and Android are alike. Both the iOS and Android phones have calling, messaging, web browsing, video chat, maps, voice commands etc. •The user interfaces of iOS and Android have a lot of similarities. Both of these support swiping, tapping, pinch and zoom etc on their phone screens. •There is a status bar on both the iOS and Android devices and it offers similar information such as battery life, time, app notifications, wifi etc. •4G cellular network can be enjoyed on both the iOS and Android devices. This is very important as cellular network is crucial for internet surfing. •Privacy settings are paramount in both iOS and Android. Users are presented with app permissions as this lessens the risk of data leakage. Swapnali Pawar
  11. 11. Differences Between iOS and Android •iOS is a closed system whereas Android is more open. Users have barely any system permissions in iOS but in Android, users can customize their phones easily. •Android software is available for many manufacturers such as Samsung, LG etc. and this may lead to some quality problems in the cheaper phones. However, iOS is strictly controlled by Apple and there is no quality problem as there are few models. •The Android applications are obtained from Google Play while iOS applications are available in the Apple app store. •Integration with other devices is better in Apple iOS as compared to Google Android. •There are different voice assistants for iOS and Android namely Siri and Google Assistant. Google assistant is much more powerful than Siri. •The running speed of iOS devices remains consistent with time. In contrast to this, the performance of Android devices may decline over time.

  16. 16. IOS LAYERED ARCHITECTURE The iOS is the operating system created by Apple Inc. for mobile devices. The iOS is used in many of the mobile devices for Apple such as iPhone, iPod, iPad etc. The iOS is used a lot and only lags behind Android in terms of popularity. The iOS architecture is layered. It contains an intermediate layer between the applications and the hardware so they do not communicate directly. The lower layers in iOS provide the basic services and the higher layers provide the user interface and sophisticated graphics. Swapnali Pawar
  17. 17. IOS LAYERED ARCHITECTURE Swapnali Pawar
  18. 18. What is the architecture of iOS ? • Architecture of IOS is a layered architecture. At the uppermost level iOS works as an intermediary between the underlying hardware and the apps you make. Apps do not communicate to the underlying hardware directly. • Apps talk with the hardware through a collection of well defined system interfaces. These interfaces make it simple to write apps that work constantly on devices having various hardware abilities. • Lower layers gives the basic services which all application relies on and higher level layer gives sophisticated graphics and interface related services. Apple provides most of its system interfaces in special packages called frameworks. • A framework is a directory that holds a dynamic shared library that is .a files, related resources like as header files, images, and helper apps required to support that library. Every layer have a set of Framework which the developer use to construct the applications. Swapnali Pawar
  19. 19. 1.Core OS Layer All the iOS technologies are build on the low level features provided by the Core OS layer. These technologies include Core Bluetooth Framework, External Accessory Framework, Accelerate Framework, Security Services Framework, Local Authorisation Framework etc. Swapnali Pawar
  20. 20. 1. Core OS Layer The Core OS layer holds the low level features that most other technologies are built upon. •Core Bluetooth Framework. •Accelerate Framework. •External Accessory Framework. •Security Services framework. •Local Authentication framework. 64-Bit support from IOS7 supports the 64 bit app development and enables the application to run faster. Swapnali Pawar
  21. 21. 2.CORE SERVICES Layer Some important frameworks are present in the CORE SERVICES Layer which helps the iOS operating system to cure itself ad provide better functionality. It is the 2nd lowest layer in the Architecture Swapnali Pawar
  22. 22. 2.Core Services Layer There are many frameworks available in the core services layer. Cloudkit Framework The data can be moved between the app the iCloud using the Cloudkit Framework. Core Foundation Framework This provides the data management and service features for the iOS apps. Core Data Framework The data model of the model view controller app is handled using the Core Data Framework. Address Book Framework The address book framework provides access to the contacts database of the user. Core Motion Framework All the motion based data on the device is accessed using core motion framework. Healthkit Framework The health related information of the user can be handled by this new framework. Core Location Framework This framework provides the location and heading information to the various apps. Swapnali Pawar
  23. 23. 3.MEDIA Layer With the help of the media layer, we will enable all graphics video, and audio technology of the system. This is the second layer in the architecture Swapnali Pawar
  24. 24. 3.Media Layer The media layer enables all the graphics, audio and video technology of the system. The different frameworks are: UIKit Graphics This provides support for designing images and animating the view content. Core Graphics Framework This provides support for 2-D vector and image based rendering and is the native drawing engine for iOS apps. Core Animation The Core Animation technology optimizes the animation experience of the apps. Media Player Framework This framework provides support for playing playlists and enables the user to use their iTunes library. AV Kit This provides various easy to use interfaces for video presentation. Swapnali Pawar
  25. 25. 4.COCOA TOUCH COCOA Touch is also known as the application layer which acts as an interface for the user to work with the iOS Operating system. It supports touch and motion events and many more features Swapnali Pawar
  26. 26. 4.Cocoa Touch Layer- The cocoa touch layer provides the following frameworks − EventKit Framework This shows the standard system interfaces using view controllers for viewing and changing calendar related events. GameKit Framework This provides support for users to share their game related data online using Game center. MapKit Framework This provides a scrollable map which can be included into the app user interface. Swapnali Pawar
