iOS System ringtone Call method

First of all, here I want to say that this is not really called the system inside the ring, because Apple does not agree with the developer calls, not to the developer interface. Assuming that the call is not online!

Then why is there so many apps in AppStore that the effect is the same as calling the system's ringtone? Why do you go to floss? In fact otherwise, they are using the same ringtone as the system! They also say that they record similar to the system ringtone. And then included in their bundle to achieve.

So, we want to implement the effect of calling the system ringtone. The only way to do this is to bundle the audio file into our bundle to invoke and play.

To a Web site, there are a lot of apple system ringtones (iOS8 also have.
