enero 18, 2020

It was this Thursday, April 8, 2010 that was held a Special Event at Apple premises, Cupertino.

The press conference started with a quick return on iPad sales. On Saturday April 3 alone, no less than 300,000 iPads were sold (450,000 so far). 600,000 e-books have been purchased and 1 million iPad apps have been downloaded.

Regarding the heart of this Special Event, it is firmware 4.0 which is at the heart of all attention. This new version will offer up to 100 new features and 1500 APIs!

But these are 7 major functions that have been highlighted.

Expected as the Holy Grail, Apple ended up integrating multitasking management applications coming from the App Store (You should know that the iPhone currently allows multitasking, but only for applications originally supplied with the iPhone (Mail, Phone, SMS, iPod, etc.).

The important point in all of this is the battery. Apple has provided special APIs to allow developers to preserve the iPhone?s battery life.

For example, it will now be possible to make a VOIP call while leaving the application, without the call being ended. Another example concerns GPS guidance applications. From now on, it will be possible to make a call without the application losing its satellite position.

Regarding GPS guidance applications, it will be possible to deactivate, one by one, the applications that use the positioning data. In addition, a new indicator in the iPhone taskbar will indicate when an application uses GPS positioning.

It will be possible to keep an application in the random access memory (RAM) without consuming it on the processor of the iPhone (CPU).

2. The application files and the background screen

At a time when the App Store, and our iPhones, abound in all kinds of applications, Apple now offers create directories in which applications can be placed according to our wishes (the name of the folder is given according to the category of the first application included in this folder but it can be renamed).

6. Game Center

The game on iPhone and iPod Touch is essential. The developers have understood the potential of Apple?s touchscreen devices and their capabilities. Apple therefore offers a ?Game center" a kind of social network where players can chat with each other, display their results in scoreboards, etc.

7. iAd

Steve Jobs wants to give the opportunity to offer free applications whose developers are paid. Apple wants to compete with audiovisual advertising by delivering "interaction and emotion". The Cupertino company will therefore host the advertisements and sell them directly.

The Apple boss wants the user not to leave the application when an advertisement is displayed. Displayed in HTML5, it can be closed with a small cross. It can integrate sound. The presentation made by Steve Jobs shows that it will, in addition, be possible to play in these advertisements of small games.

60% of the revenues generated by advertisements in the applications will go to developers.
