Storyboard - setting delegates

Question

Before storyboards I was able to set delegates and datasources just by dragging an outlet to a class. With storyboards, I cannot drag the outlet to another view controller;

Answer 1

If your storyboard segue destination View Controller is an UIViewController then @Marco answer is right. But if your destination View Controller is a UINavigationViewController then you have to get the UIViewController from UINavigationViewController :

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Check the segue identifier
    if ([segue.identifier isEqualToString:@"chooseCategoryType"])
    {
        // Get a reference of your custom view controller if your segue connection is an UIViewController
        // CustomViewController *customViewController = segue.destinationViewController;
        // Get a reference of your custom view controller from navigation view controller if your segue connection is an UINavigationViewController
        CustomViewController *customViewController = [[[segue destinationViewController] viewControllers] objectAtIndex:0];

        // Set your custom view controller's delegate
        customViewController.delegate = self;
    }
}
