copied!<p>To send values to parent controller you have to use protocols. I will provide proper steps you should take in order to have your desired functionality working.</p> <p>1. Create a protocol for your AddTeacherToCourseController. In your AddTeacherToCourseController.h add the following right below the imports:</p> <pre><code>@protocol AddTeacherToCourseControllerProtocol <NSObject> - (void)yourDelegateMethod:(Teacher *)insegnante; @end </code></pre> <p>And below interface tag add:</p> <pre><code>@property (strong, nonatomic) id <AddTeacherToCourseControllerProtocol> delegate; </code></pre> <p>2. In AddTeacherToCourseController.m:</p> <pre><code>-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // I would use the existing array you are using to display the teachers in order to select the correct one you want to send back like this: // Teacher *teacher = [self.teachers getTeacherInPosition:indexPath.row]; [self.delegate yourDelegateMethod:[yourTeacherArray objectAtIndex:indexPath.row]]; } </code></pre> <p>[this method will call your delegate method through the protocol and will pass your selected professor to the parent controller]</p> <p>3. In your parent controller, your newCourseViewController.h right after interface line add:</p> <pre><code><AddTeacherToCourseControllerProtocol> </code></pre> <p>4. If you do not have an Insegnante button action, create one in interface builder [dragging and naming]. Then add the following to this action:</p> <pre><code>// assuming your storyboard is named MainStoryboard. here you create your segue programmatically: UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; addTeacherToCourseViewController *addTeacherController = (addTeacherToCourseViewController *)[storyBoard instantiateViewControllerWithIdentifier:@"addTeacherToCourseViewController"]; addTeacherController.delegate = self; [self.navigationController pushViewController:addTeacherController animated:YES]; </code></pre> <p>5. In Interface Builder:</p> <ul> <li>Remove your segue from Insegnante button.</li> <li>Edit the Storyboard Id of 'addTeacherToCourseViewController' to 'addTeacherToCourseViewController'</li> </ul> <p>6. In newCourseViewController.h write your delegate method:</p> <pre><code>- (void)yourDelegateMethod:(Teacher *)insegnante{ // Do whatever you want with your Insegnante // and be sure to pop the second controller from the view stack: [self.navigationController popViewControllerAnimated:YES]; } </code></pre> <p>Let me know if you have questions and if my answer helped anyone. </p>
