How to read sms message on iOS?

I wanna make a application which can read SMS message through bluetooth headset automatically when it arrives.

I think this could be very useful when driving a car.

To do this,

1. able to detect SMS arriving.
2. able to get SMS text message.
3. able to encode SMS text as TTS stream.(I have my own TTS Engine, so this doesn't matter)
4. send stream through bluetooth headset which already paired.

Is there someone could hel开发者_如何学JAVAp me? :)

it's not possible on standard iOS. The sms API is not exposed, hence interaction with the message application or database is not possible. Jailbroken Apps might be able to use the SMS interface somehow, tho. I would start going into that direction.
