SMS window wont dismiss objective-C

Hi I'm trying to make a SMS native extension for adobe AIR. I Havnt coded in objective-c before but everything works fine except for the fact that the SMS window won't close when pressing send or cancel. Below is the main section of code but ask me if you need any more info. Thanks for reading. also why is xcode telling me :"Method in protocol not implemented" for the second line ? ``` #import "SMSComposerHelper.h" @implementation SMSComposerHelper //Event name static NSString *event_name = @"SMS_COMPOSER_EVENT"; -(void) sendSMS:(NSString *)toRecipient messageBody:(NSString *)messageBody { FREDispatchStatusEventAsync(context, (uint8_t*)[event_name UTF8String], (uint8_t*)[@"WILL_SHOW_MAIL_COMPOSER" UTF8String]); MFMessageComposeViewController *smsComposer = [[MFMessageComposeViewController alloc] init]; smsComposer.messageComposeDelegate = self; //make string into array NSArray *recipientArray; recipientArray = [NSArray arrayWithObjects: toRecipient, nil]; smsComposer.body = messageBody; smsComposer.recipients = recipientArray; //show sms composer [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentModalViewController:smsComposer animated:YES]; } // Dismisses the sms composition interface when users tap Cancel or Send. -(void) smsComposeController: (MFMessageComposeViewController*)controller didFinishWithResult: (MessageComposeResult)result error:(NSError*)error { NSString *event_info = @""; // Notifies users about errors associated with the interface switch (result) { case MessageComposeResultCancelled: event_info = @"SMS_CANCELED"; break; case MessageComposeResultSent: event_info = @"SMS_SENT"; break; case MessageComposeResultFailed: event_info = @"SMS_FAILED"; break; default: event_info = @"SMS_UNKNOWN"; break; } FREDispatchStatusEventAsync(context, (uint8_t*)[event_name UTF8String], (uint8_t*)[event_info UTF8String]); FREDispatchStatusEventAsync(context, (uint8_t*)[event_name UTF8String], (uint8_t*)[@"WILL_HIDE_SMS_COMPOSER" UTF8String]); context = nil; //hide mail composer [[[[UIApplication sharedApplication] keyWindow] rootViewController] dismissModalViewControllerAnimated:YES]; } -(void)setContext:(FREContext)ctx { context = ctx; } @end ``` RESPONSE : Omar thankyou so much for your answer and for answering so quickly! First I tried your solution of using ``` [controller dismissModalViewControllerAnimated:YES]; ``` but this did nothing so I changed it back. My header already was : ``` @interface SMSComposerHelper : NSObject<MFMessageComposeViewControllerDelegate> { ``` So I decided to focus on fixing the warning. The warning was solved by changing : ``` -(void) smsComposeController: (MFMessageComposeViewController*)controller didFinishWithResult: (MessageComposeResult)result error:(NSError*)error ``` to: ``` - (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result ``` I would love to know why this worked ? do you know Omar ? So I solved the warning but it still didn't dismiss. So I tried your suggestion again: ``` [controller dismissModalViewControllerAnimated:YES]; ``` AND IT WORKED !!!! thanks so much man. You don't know how many hours I was stuck for. I will be happy to accept your answer.
