Four web technologies and features created by Apple that shine in the new iOS 8

Apple has quietly been making enhancements to the mobile version of Safari, boosting performance, adding features and in general ensuring that the devices could deliver a browsing environment that is as close as possible to what’s available on a desktop. The focus of web technologies by Apple continues with iOS 8, that would introduce what perhaps are some of the biggest changes to Safari.

One of the biggest changes in iOS 8 is the speed bump for applications which feature embedded web views that are powered by WebKit, the engine behind Safari. In 2008, with the iOS 4.3 launch, WebKit was equipped with a high-performance scripting engine that could translate JavaScript dynamically. The new Extensibility features allow all applications to enjoy the same performance level as Safari.

Another net technology feature is the 3D graphics for hardware acceleration. However, this feature is not exactly new. WebGL, a technology that makes 3D programming on the web was released in the year 2001 and present in the program for various iOS versions. Nonetheless, Apple opted to disable it by default and made the technology impossible for third party applications to use by hiding the software switch which turns it on behind a private API. WebGL would be turned on by default, providing users full access to any site offering content through this system. This would open a new door to new applications.

The Safari iOS 8 version comes with several video playback improvements that fall primarily in two categories, power saving and media management. Apple has implemented on the power-saving side several tricks that enable media playback to use less battery. Now, video is directly composited in hardware and technologies such as HTTP Live Streaming have been extended to give video streams that are fully adaptive, load faster and use less bandwidth. With media management, engineers have enhanced the capability for JavaScript to interact with video content and even implemented a new technology called Media Source Extensions which enable JavaScript to generate and maneuver streams directly from within the internet page.

The new web hardware features can usher in all kinds of new apps that utilize video on the net, such as interactive multi-angle playback, time-shifting live streams and so much more.  A final set of enhancements to iOS 8 boost the framework with support for the overall continuity program of the operating system, enabling applications to communicate better across devices and across distribution media as well.

The improvements, along with smaller items such as support for advanced CSS directives, are proof that Apple is as serious as ever in terms of providing users of iOS with a superior web platform. Moreover, it views technologies such as HTML as valuable companions to the native frameworks, instead of as competition to it. Some of the enhancements like playback and WebGL are based on standards that are available openly on other platforms, including Android and Windows, making it easier than ever for net designers and developers to create apps that work across a huge range of devices.


What’s New in Objective-C foundation for iPhone Application Developers in iOS 7?

Objective-C is one of the most common languages for developing iOS apps. Some other third party frameworks allow developing apps using other languages such as HTML & JavaScript or C#, but if developer wants to write blazingly fast, super-efficient iOS native apps then they need to use Objective-C foundation which is the core frameworks that is mainly used by modern day’s iPhone developers.

For iOS developer, it’s important to keep up-to-date with the latest updates that happens in Objective-C and Foundation – and in iOS 7, there are some important changes that they must know about.

1. New return type

A new type has been added to Objective-C, called instance type. This type can only use with a return type from an Objective-C and this s used as a hint to the compiler that the return type of the method will be an instance of the class in which any type of the method belongs.

2. New Foundations:

One of the big update that comes with this release is of a new foundation that lies in the networking. In fact, that there’s a complete chapter that is dedicated to it in iOS 7 Tutorials.

3. Native implementation for encoding and decoding NSData:

Data is one of most important things that developer needs to deal with a lot when programming. NSData is the common foundation class that captures raw bytes and provides effective solutions for manipulating those bytes, as well reading and writing data to and from a file. In NsData, there is one common task of encoding and decoding for which there’s been no native implementation available in the earlier versions that is available in the iOS 7 version.

Updated Features For IOS 7

4. NSProgress:

It’s often happening that totally new classes get added to the Foundation. It’s a pretty stable framework; the reason behind this is that there is a new core class which is not required too often. However, iOS 7.0 comes up with an entirely new class named NSProgress. This new class aims to deliver progress reporting throughout Objective-C code, that separating the progress of individual components. For example, if any developer performs a few tasks which can monitor its own progress and report back to its parent task.

Base64 is a group of binary-to-text encoding schemes that represent binary data in machine understand ASCII format. These schemes are mostly used where there’s a requirement for encoding the binary data to be stored or transferred to deal solely with textual data. This ensures the data remain unchanged without any type of modification.

5. NSTimer:

So many times Timers often find homes in apps that perform periodic tasks. As useful as they may be, the problem is that they may runs constantly when several timers are in use. This means the CPU is constantly active. Moreover, it would be much more efficient if the CPU woke up, performed a series of tasks and then went back to sleep. To resolve this issue, In iOS & apple has added a tolerance property to help accommodate this behavior.

Thus, this version of iOS 7 able to helps developer to create more effect and easiest solutions with the help of Objective-C language. Moreover, this version of iOS solves many technical difficulties that are face by developer while developing their iPhone apps using Objective-C language.
