iOS pass data when using storyboard to push the view controller

Question

I am starting to use storyboard more often but I have run into a problem. Usually when you push a view controller using a UINavigationController you do it in the following way and you are able to pass data along with it:

UIViewController *vc = [[UIViewController alloc] init];
vc.link = [self link];
vc.name = [self name];

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc]
[nav presentViewController:vc completion:nil animated:YES];

(I did the above code for memory so it may not be 100% correct).

Now that I am using storyboard, I am not instantiating the view controllers myself so how do I pass data with it? Thanks!

Answer 1

Use the prepareForSegue:sender: method.

For example:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"SegueID"])
    {
        UIViewController * vc = segue.destinationViewController;
        vc.link = [self link];
        vc.name = [self name];
    }
}

Or, if your destination view controller is a UINavigationController, use this:

UINavigationController * navigationController = segue.destinationViewController;
UIViewController * vc = [navigationController.viewControllers objectAtIndex:0];
