I have a viewController that is usually (most often) accessed by using a push segue. This viewController needs to be embedded in a UINavigationController. So typically, this is no problem. The push segue manages pushing the viewController, and therefore the viewController has it's UINavigationController.
My issue is that in a few cases, I'd like to present this same exact viewController using a modal segue. When I do this, the viewController is not embedded in a navigationController. Is there a way to do this using segues?
I know this can be done purely in code without segues by creating a UINavigationController, setting the rootView as the viewController and then presenting that modally. That can be done using code like this :
MyViewController *viewController = [[MyViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self presentModalViewController:navController animated:YES];
But how do I do this same thing but using Segues?
Update
For further clarity, here is some code to supplement how I used the accepted answer in the prepareForSegue method.
When Using Modal Segue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue destinationViewController] isEqualToString:@"Modal to MyVC"])
{
UINavigationController *nav = [segue destinationViewController];
MyViewController *vc = [nav topViewController];
//setup vc
}
}
When Using Push Segue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue destinationViewController] isEqualToString:@"Push to MyVC"])
{
MyViewController *vc = [segue destinationViewController];
//setup vc
}
}
