IOS is the operating system that runs on iPad, iPhone, and iPod touch devices. The operating system manages the device hardware and provides ios developer the technologies required to implement native apps. The operating system also ships with various system apps, such as Phone, Mail, and Safari, that provide standard system services to the user. The iOS Software Development Kit (SDK) contains the tools and interfaces needed to develop, install, run, and test native apps that appear on an iOS device’s Home screen. Native apps are built using the iOS system frameworks and Objective-C language and run directly on iOS. Unlike web apps, native apps are installed physically on a device and are therefore always available to the user, even when the device is in Airplane mode. They reside next to other system apps, and both the app and any user data is synced to the user’s computer through magento development company iTunes At the highest level, iOS acts as an intermediary between the underlying hardware and the apps you create. Apps do not talk to the underlying hardware directly. Instead, they communicate with the hardware through a set of well-defined system interfaces. These interfaces make it easy to write apps that work consistently on devices having different hardware capabilities. The implementation of iOS technologies can be viewed as a set of layers, which are shown in  Lower  layers contain fundamental services and technologies. Higher-level layers build upon the lower layers and provide more sophisticated services and technologies. As you write your code, it is recommended that you prefer the use of higher-level frameworks over lower-level frameworks whenever possible. The higher-level frameworks are there to provide object-oriented abstractions for lower-level constructs seo services

. These abstractions generally make it much easier to write code because they reduce the amount of code you have to write and encapsulate potentially complex features, such as sockets and threads. You may use lower-level frameworks and technologies, too, if they contain features not exposed by the higher-level frameworks. custom software development company iOS 8 lets you extend select areas of the system by supplying an app extension, which is code that enables custom functionality within the context of a user task. For example, you might supply an app extension that helps users post content to your social sharing software development services website. After users install and enable this extension, they can choose it when they tap the Share button in their current app. Your custom sharing extension provides the code that accepts, validates, and posts the user’s content. 

The system lists the extension in the sharing menu and instantiates it when the user chooses it. In Xcode, you create an app extension by adding a preconfigured app extension target to an app. After a user installs an app that contains an extension, the extension can be enabled by the user in the Settings app. When it companies in nashik the user is running other apps, the system makes the enabled extension available in the appropriate system UI, such as the Share menu. iOS supports app extensions for the following areas, which are known as extension points: Share. Share content with social websites or other entities. Action. Perform a simple task with the current content. Widget. Provide a quick update or enable a brief task in the Today view of Notification Center. Photo editing. Perform edits to a photo or video within the php development company Photos app. Document provider. Provide a document storage location that can be accessed by other apps. Apps that use a document picker view controller can open files managed by the Document Provider or move files into the Document Provider. Custom keyboard. Provide a custom keyboard that the user can choose in place of the system keyboard for all apps on the device. Each extension point defines appropriate APIs for its purposes. When you use an app extension template to begin development, you get a default target mobile app development company that contains method stubs and property list settings defined by the extension point you chose.
