Question

I simply want to add a navigation bar (with some nav bar button) on a presented modal controller with storyboard.

Programmatically with XIBs, it looks like that :

SDMapController *mapController = [[SDMapController alloc] initWithNibName:@"SDMapController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mapController];

[self presentModalViewController:navigationController animated:YES];

But I have no idea how to handle it with Storyboard. I guess i have to implement some code on the -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender method but since the destinationController property of segue object is readonly, i don’t really know how to do this.

Any idea ?

You have to implement the prepare for segue, only if you want to pass on some data to your presented view controller. Otherwise you can leave it empty. The presenting of the View Controller is from the Interface Builder. You add a navigation controller with it’s root view controller and make a segue (ctrl + drag) to the navigation controller. Set the segue type to modal, and give it an ID. You can trigger this segue from code by calling [self perforSegueWithIdentiefier:@"MySegueID"];. If you dragged the segue from a button or a table view cell, it will be triggered automatically when you tap on it, without calling this method. As I said, in the prepareForSegue method, the segue.destinationViewController will bee the presented navigation controller. You can access it’s topViewController if you need and pass some data to it.
