如何从其他故事板场景中的主要故事板场景访问变量？

Question

I am developing an app that has 3 storyboard scenes. In the first storyboard scene, I have some variables that I want to access in other two scenes. How can I do it? I navigate to other two scenes using Storyboard segue and calling the following on button click

[self performSegueWithIdentifier:@"nameofsegue" sender:self];

Answer 1

Use this method

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"nameofsegue"]) {
        YourDestinationVC *dvc = [segue destinationViewController];
        YourSourceVC *svc = (YourSourceVC*)sender;
        //set your ivr here
    }
}
