It is a great merit that it is possible to receive incoming calls even while launching other applications and working.


Run the navigation application in the background ... ....


You can receive route guidance while listening to music. It is exactly the same function as a car stereo integrated navigation system.


From the viewpoint of privacy protection, if an application running in the background asks for user's location information, you can check whether to provide location information.


Also, if you are asking for location information, you can check with the icon in the upper right corner of the screen as well as the pop-up.


For Apple's push notification service, we had to go through an Apple server in the past, but it is said that it is no longer necessary to go through an Apple server.


And it also adopts the function which can switch the application immediately while keeping the play state of the game being played and the execution state of the application.


Seven services including these are realized by multitasking.

In other words, it will be seen by users a billion times a day.


The merit of "iAd". IAd is built in the iPhone OS, and advertisements can be inserted by the application developer. 60% of sales is paid to the developers of the application.
