How to push from view controller to navigation view controller using prepareForSegue method?

I have a project which has a view controller as initial screen and then a view controller embedded inside a navigational view controller. I also have a button on first screen on click of which I want the navigational controller screen to be opened.

I clicked on button and then on ' connections inspector', I added push event to that navigational controller, but segue is not happening. How could I achieve it please?


Finally after a bit of research I managed to get this thing working. Here is the code i am using:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
NSLog(@"Source Controller = %@", [segue sourceViewController]);
NSLog(@"Destination Controller = %@", [segue destinationViewController]);
NSLog(@"Segue Identifier = %@", [segue identifier]);

if ([segue.identifier isEqualToString:@"mysegue"])
NSLog(@"coming here");

SecondViewController *loginViewController = (SecondViewController *)segue.destinationViewController;

//SecondViewController *navigationController = [[UINavigationController alloc]init];

[self presentModalViewController:loginViewController animated:YES];

Are you sure that the Navigation Controller's connection to the embedded view controller is set up correctly? The first view controller should be connected to the Navigation Controller, with a Push style segue, and the navigation controller should be connected to the second view controller, with a Relationship style segue.

At any rate, one of the official Apple tutorials does just this, so you might be able to compare your code to it and see if there's a difference: Your Second iOS App. The prepareForSegue method itself isn't really involved with firing the segue; it is just invoked before the segue runs to prepare the new view controller.
