Present View From Storyboard Programmatically

Question

I am very new to using Storyboards, and am trying to learn. In my app, I want to change from one view to another, modally, without pushing any buttons, ie timer runs down then performs the action. I added a notification observer in the main view, and in my storyboard, I added a new view controller, and associated the Custom Class with it called URLWebViewController . In code I wrote out:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
URLWebViewController *myVC = (URLWebViewController *)[storyboard instantiateViewControllerWithIdentifier:@"URLWeb"];
[self presentViewController:myVC animated:YES completion:nil];

But I get the warning message

Incompatible pointer types sending 'URLWebViewController' to parameter of type 'UIViewController'

Like I said, I am very new to Storyboards, and here is what it looks like currently:

Answer 1

Your screenshot indicates you have not created a segue between the two view controllers. Do so by click-and-drag from one view controller to the other. In the attribute inspector, give your newly-created segue an identifier, ie, a string that names it.

To trigger this segue programmatically, in your source view controller (the one you are segueing from) just call performSegueWithIdentifier and pass in the identifier you chose.

Answer 2

It's really simple! I didn't understand the order but let's say you want to pass from ViewController to WebViewController (the name from your storyboard)..Just ctrl-drag from ViewController to WebViewController to create a segue and select modal as the type.

Now click on the line that connects your view controllers and in the right panel give it an identifier. Now in your code just use the method performSegueWithIdentifier using the identifier you wrote.
