问题
I would like to send an SMS from an iPhone but MFMessageComposeViewController pops up the message,I would like to send the SMS when an event or notification occurs in the application.Is it possible through iOS SDK or are there any legitimate low level function which can be used to accomplish the same.

It's not possible to send SMS messages programmatically through the iOS SDK. As you can imagine, if the SDK allowed this, it would open a huge can of worms in terms of developer abuse.
If the SMS messages don't have to come from the user's phone number, you can take a look at the Twilio API (http://www.twilio.com/sms).
