iPhone OS 4 - officially presented

Wait! April 8 at 21.00 on Moscow hosted the presentation of the next of Apple, where Steve Jobs introduced a new version of the operating system for the iPhone - iPhone OS 4.


Innovations

So, while the exact dates of the system is not known - is expected in the summer. But it is already available in SDK, which added more than 1500 new features, some of them: access to calendar, photo gallery, podderzhra Bluetooth-keyboards, create play-lists.

iPhone OS 4 multi-tasking! To switch between applications rather double-click the Home button and you will see all running applications.

As Steve said, the problem of the introduction of multi-tasking was to reduce the working hours of the gadget, but Apple engineers were able to find a compromise.

iPhone learned to talk! Now you can get "voice" message from the navigator will be minimized as of and we have run some other application.

Task completion, Completing the job. Started a load photos on Flickr? It is safe to send the application in the background, she will cope with this task alone.

Folders - Now you can group applications. This allows you to store on your iPhone instead of 180 applications, 2160. In order to combine applications into one group, just drag the icon to another application.

iBooks - Together with the new firmware, users will be able to buy and read books in the iBooks.

Game Center - Certain social network. A record of personal achievements, statistics and much more.

Unified mailbox. Added ability to sort messages in the trees. It is worth noting that the mail client has not been updated since 2007.

iAd - Mobile advertising. This is not traditional advertising, which we used to always see. According to Steve Jobs, Apple strongly wants to raise the level of advertising, to combine the emotional impact and interativnost. The most interesting is that the user will see some ads without leaving your application. Apple intends to take 40% of the revenue from advertising, while 60% give the developer. Example:

That's all that was shown at the presentation. IPad owners will have to wait until the fall, to get a new version of the system.

In iPhone-OS 4.0 multitasking did not appear
(Article from the blog of Ilya Birman)

Multitasking - it is usually common feature for ticks, and it is not clear why this features so demanding users. What is the use of the fact that any application can hang in the background and eating resources? This is a riddle. Meanwhile, marketers competitors thoroughly brainwashed audience, saying that the iPhone is not multitasking. Since the sounds are cool and modern, and generally, in other devices it is, all demanded Epply this. But because users are simply not entered as speech here, then Eply figured out what to do: Just say the word "multitasking" to all shut up on the fact that it is not. Make multitasking is not necessary, because it is a bad feature.

Two of the thesis:

1. Operating System iphone supports multitasking.
2. Applications written by third parties are prohibited to stay and do something in the background.

Both these statements are true for all versions of iphone firmware from 1.0 to 4.0. Multi-tasking as she was, and remains (otherwise how do you get incoming calls or SMS, or reminders while you play Sudoku with music from the ipod?) As a backdrop to hang neeplovskim applications as it was impossible, and now it is impossible (so no bad program a secret from you can not do anything).

Instead of simply enable the third-party applications in the background, Eply solve specific problems, which are the users of the lack of such opportunities. The first was a push - a notification from the server. Push decided, for example, the problem of instant messengers. Instead of leaving all the spin background of great application, Goethe Institute (or, worse yet, a few such applications, with all their screens, icons, and goodness knows what else), Eply wrote their Super and super-fast background process, which alone handles all the notifications for all programs, and may, if necessary to run any program.

Users of this kitchen does not see. For example, he uses the application "Goethe Institute" and is sitting in a chat with Vasya, and then goes out and runs the browser. All of a sudden appears on the screen that Vasya wrote "Let's go to the movies." The fact that the appearance of this message is caused eplovskim service did not care. If he presses the cancellation, then the application "Goethe Institute" does not even know about it all, and if too tight on the "Reply", the "Goethe Institute" runs and shows him a dialogue with exactly the same place.

Push decided not to all problems. Background music plays from other people's applications (for example, Internet radio) or the background tracking of GPS-coordinates of the user (for geo-social widgets) remain elusive.

In firmware 4.0 Eply solve these problems, the solution is released under the brand "Multitasking". In reality, they simply add a background service, which can play music, and its service, which monitors the GPS-coordinates, as well as an IPA for the interaction of software from them. And a couple of other services. Everything. Third-party software still will not let anyone just hang and take the memory and processor. So still there will be no Task Manager, and the background program can not hang, because the OS will just kill her when entering the home screen, as do the first, second and third flash.
