    To Use Unwind Segues in iOS. 1- Create three controller using storyBoard
    2- Push from FirstViewControleller to SecondViewController
    3- Push From SecondViewController to Third

    Write a function in FirstViewController like this

    -(IBAction)prepareForUnwind:(UIStoryboardSegue *)segue {
    if ([segue.identifier isEqualToString:@"ThirdViewID"]) {
        ThirdViewController *threeVC = (ThirdViewController *)segue.sourceViewController;
        NSLog(@"color are %@", threeVC.mySelectedColor);
    }}


    4 - Create two button with title "Red" & "Blue"
    5-Drag Home button on thirdViewcontroller to the Exit outlet to create our Unwind Segue
    6- Write ibaction for two button "Red" & Blue like this

    - (IBAction)redAction:(id)sender {
    self.mySelectedColor = @"Red";
    [self performSegueWithIdentifier:@"ThirdViewID" sender:self];
}
- (IBAction)blueAction:(id)sender {
    self.mySelectedColor = @"Blue";
    [self performSegueWithIdentifier:@"ThirdViewID" sender:self];
