Apple's iOS operating system
[attachment=52587]
Abstract:
iOS is Apple's mobile operating system developed originally for the iPhone, and later deployed on the iPod Touch and iPad as well. It is derived from Mac OS X, with which it shares the Darwin foundation, and is therefore a Unix-like operating system, by nature. In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device's storage.
Version 4, announced in April 2010, introduced multitasking as well as several business-oriented features, including encryption for email and attachments. At the WWDC 2010 keynote on June 7, 2010, Apple announced that iPhone OS had been renamed iOS. Apple licenses the trademark for "iOS" from Cisco Systems (who own IOS), the same company with which Apple had earlier settled a dispute over the "iPhone" trademark.
iOS 4 was released on June 21, 2010, three days before the iPhone 4. Staggering product launches reduces strain on Apple's servers. iOS 4 is the first version of the OS to be a free upgrade on the iPod touch; Apple had charged $9.99 for earlier upgrades. Apple previously announced that iPad users with 3.x software would receive a free upgrade to thenextmajor(4.x)release.
Introduction:
iOS is Apple's mobile operating system. Developed originally for the iPhone, it has since been shipped on the iPod Touch and iPad as well. Apple does not permit the OS to run on third-party hardware. As of June 7, 2010, Apple's App Store contained more than 225,000 iOS applications, which had collectively been downloaded more than five billion times.
The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons. The response to user input is immediate and provides a fluid interface. Interaction with the OS includes gestures such as swiping, tapping, pinching, and reverse pinching. Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching from portrait to landscape mode).
iOS is derived from Mac OS X, with which it shares the Darwin foundation, and is thereforea Unix-like operating system by nature.
In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device's storage. iOS (known as iPhone OS before June 2010) is Apple's mobile operating system. Originally developed for the iPhone, it has since been extended to support other Apple devices such as the iPod touch, iPad and Apple TV. Apple doesn't license iOS for installation on third-party hardware. As of May 31, 2011, Apple's App Store contains more than 500,000 iOS applications, which have collectively been downloaded more than 15 billion times. In the last quarter of 2010, it had a 26% share of the smartphone operating system market in terms of units sold, behind Google's Android and Nokia's Symbian. As of May 2010, it accounted for 59% of mobile web consumption—not including the iPad—in North America.
History:
The operating system was unveiled with the iPhone at the Macworld Conference & Expo on January 9, 2007, and released in June of that year. At first, Apple marketing literature did not specify a separate name for the operating system, stating simply that the "iPhone runs OS X".Initially, third-party applications were not supported. Steve Jobs argued that developers could build web applications that "would behave like native apps on the iPhone". On October 17, 2007, Apple announced that a native Software Development Kit (SDK) was under development and that they planned to put it "in developers' hands in February".On March 6, 2008, Apple released the first beta, along with a new name for the operating system: "iPhone OS".
Brisk sales of Apple mobile devices kindled interest in the SDK. The previous September, Apple had released the iPod touch, which had most of the non-phone capabilities of the iPhone. Apple also sold more than one million iPhones during the 2007 holiday season. On January 27, 2010, Apple announced the iPad, featuring a larger screen than the iPhone and iPod touch, and designed for web browsing, media consumption, and reading iBooks.
In June 2010, Apple rebranded iPhone OS as "iOS". The trademark "IOS" had been used by Cisco for over a decade for its operating system, IOS, used on its routers. To avoid any potential lawsuit, Apple licensed the "IOS" trademark from Cisco.[
Overview:
Apple's iOS did not have an official name until the release of the iPhone software development kit (iPhone SDK) on March 6, 2008. Before then, Apple marketing literature simply stated that their iPhone runs a version of "OS X", a reference to iOS's parent, Mac OS X.[3] When introduced, it was named iPhone OS. It was renamed iOS on June 7, 2010, presumably since it is now designed for three devices other than the iPhone.
As of July 25, 2011, the current version of iOS is 4.3.5 for iPhone (GSM), iPod touch, iPad. That same day a special iOS build, 4.2.10, was released for the CDMA iPhone. The latest version for Apple TV (second generation), 4.3/4.2.2, was released on May 11, 2011.
However, the first generation iPod touch and iPhone have iOS 3.1.3 as their latest version; and the second generation iPod touch and iPhone 3G have iOS 4.2.1 as their latest version. The Developer Beta for version 3.0 was made available on March 17, 2009, with iOS 3.0 being released June 17, 2009.
On April 8, 2010, Apple previewed iOS 4.0 to the public, and launched a beta of the 4.0 firmware and SDK. 4.0 beta had only been available to registered developers, and the final version was released on June 21, 2010. 4.0 is reported to have over 1500 new APIs for developers, with the highly anticipated multitasking feature.
SDK Features:
Developers are able to set any price above a set minimum for their applications to be distributed through the App Store, of which they will receive a 70% share. Alternately, they may opt to release the application for free and need not pay any costs to release or distribute the application except for the membership fee.
Since its release, there has been some controversy regarding the refund policy in the fine print of the Developer Agreement with Apple. According to the agreement that developers must agree to, if someone purchases an app from the app store, 30% of the price goes to Apple, and 70% to the developer. If a refund is granted to the customer (at Apple's discretion), the 30% is returned to the customer from Apple, and 70% from the developer; however, Apple can then take another 30% of the cost from the developer to make up for Apple's loss.
Digital rights management:
The closed and proprietary nature of iOS has garnered criticism, particularly by digital rights advocates such as the Electronic Frontier Foundation, computer engineer and activist Brewster Kahle, Internet-law specialist Jonathan Zittrain, and the Free Software Foundation who protested the iPad's introductory event and have targeted the iPad with their "Defective by Design" campaign. Competitor Microsoft, via a PR spokesman, has also criticized Apple's control over its platform.
At issue are restrictions imposed by the design of iOS, namely DRM intended to lock purchased media to Apple's platform, the development model (requiring a yearly subscription to distribute apps developed for the iOS), the centralized approval process for apps, as well as Apple's general control and lockdown of the platform itself. Particularly at issue is the ability for Apple to remotely disable or delete apps at will.
Conclusion:
Over 425,000 ways to make iphone even better. The apps that come with your iPhone are just the beginning. Browse the App Store to find hundreds of thousands more, all designed specifically for iPhone. This means there’s almost no limit to what your iPhone can do. While everyone else was busy trying to keep up with iPhone, we were busy creating amazing new features that make iPhone more powerful, easier to use, and more indispensable than ever. The result is iPhone 4. The biggest thing to happen to iPhone since iPhone.
