iOS Button that performs multiple actions - ios

Question

I have a button at the end of a guide that says Done!I need it to bring up Facebook posting dialogue and also segue back to the menu screen
At the moment I have it opening a Facebook posting screen, which pops up and goes back down when you click post or cancel. I would like it to return to the menu after the facebook process has completed. I have followed a guide on how segue programatically and have added the code to my current postToFacebook IBAction but it didn't work. I then tried to create it's own IBAction and link it to the button but it didnt work either.
Does anyone know how I can get it to segue after the Facebook dialogue
Heres my code for facebook posting in case you need it
- (IBAction)PostToFacebook:(id)sender {
mySLComposerSheet = [[SLComposeViewController alloc] init];
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[mySLComposerSheet setInitialText:#"I just followed a guide on this App - Get it on the App Store http://"];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
And heres the code for the programatic segue
-(IBAction)nextView{
[self performSegueWithIdentifier:#"next" sender:self]; }

Answer 1

You can put all code in a single -(IBAction) and use a boolean value that changes it's value after executing facebook action.
Something like this,
- (IBAction)PostToFacebook:(id)sender {
if(valueOfBoolean==TRUE){
mySLComposerSheet = [[SLComposeViewController alloc] init];
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[mySLComposerSheet setInitialText:#"I just followed a guide on this App - Get it on the App Store http://"];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
valueOfBoolean=FALSE;
}
else{
[self performSegueWithIdentifier:#"next" sender:self];
}
}
Set default value for valueOfBoolean as TRUE in viewDidLoad method.

EDITED :
- (IBAction)facebook:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *facebook = [[SLComposeViewController alloc]init];
facebook = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[facebook setInitialText:[NSString stringWithFormat:#"your string"]];
[self presentViewController:facebook animated:YES completion:nil];
[facebook setCompletionHandler:^(SLComposeViewControllerResult result){
NSString *output;
switch (result) {
case SLComposeViewControllerResultCancelled:
// here you can handle your seque, or your custom action what you want
break;
case SLComposeViewControllerResultDone:
// here you can handle your seque, or your custom action what you want
break;
default:
break;
}
// [self dismissViewControllerAnimated:YES completion:nil];
}];
}
else{
UIAlertView * alertView = [[UIAlertView alloc]initWithTitle:#"No Facebook Account" message:#"There are no Facebook accounts configured. You can configure or create accounts in settings ." delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:nil];
[alertView show];
}
}
I hope it helps !
