SMS option not working properly - iphone

Question

I am using xcode 4.2 and i am developing an iphone APP , part of this app is sending SMSs
here is the code that I typed:
-(IBAction)SMSbutton{
MFMessageComposeViewController *sms = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText]) {
sms.body= [NSString stringWithFormat: #"text"];
sms.messageComposeDelegate = self;
[self presentModalViewController:sms animated:YES];
}
I can open the SMS application and send SMS but the problem is whether I click on the "cancel" or the "send" button the message application does not go away . how to do that ?
thanks

Answer 1

Set your calling class to be a delegate of the message composer, then catch the cancel and send events to dismiss the modal view controller as needed.
Set your header file to adhere to the MFMessageComposeViewControllerDelegate, and when you initialize the composer, set the message delegate to self:
MFMessageComposeViewController *george = [MFMessageComposeViewController alloc] init];
george.messageComposeDelegate = self;
Then implement the delegate method...easiest way is:
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissModalViewControllerAnimated:YES];
}
...but you can catch and deal with errors and events as necessary.

Implement messageComposeViewController:didFinishWithResult: in your delegate"
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
if(result == MessageComposeResultCancelled) {
//Message cancelled
} else if(result == MessageComposeResultSent) {
//Message sent
}
[self dismissModalViewControllerAnimated:YES];
}

Have you tried dismissViewControllerAnimated:completion: or dismissModalViewControllerAnimated:?
[self dismissModalViewControllerAnimated: YES];
