The didFinishWithResult delegate method of MFMessageComposeViewController shows that the message has been sent successfully, even when the device is in airplane mode or when the device has no SIM,but the message sending is failed.The delegate does not go through the failure state.Why doesnt it go to failure state?.Please give me some suggestion on this.
