Question

I’m sure there is an easy way to do this that I am obviously missing.

I have three classes in my UINavigation Controller:

1. MasterNavViewController – of type UINavigationController – owns the properties across all the subsequent view controllers.
2. FirstNavViewController – of type UIViewController.
3. SecondNavViewController – of type UIViewController.

For reasons of threading that I don’t want to go into here I would like to move from the FirstNavViewController to the SecondNavViewController using code. I have tried:

[self.navigationController pushViewController:SecondNavViewController animated:YES];

but I am getting an error in my code: Use of undeclared identifier ‘SecondNavViewController’ did you mean MasterNavViewController?

I’m not exactly sure how to proceed with this. I have tried importing my SecondNavViewController.h but that doesn’t seem to work either.

I’m thinking perhaps I am trying to do this the wrong way. Any pointers would be greatly appreciated! James

As Requested:
I’m not creating the SecondNavViewController explicitly in the code, I’m not sure how… but that’s where I’m going wrong most likely right?. I have created the classes & then linked them with the UIViewController that I dragged into IB. Typically I would just create a push segue between the two but in this case I do not want to do that.

SecondNavViewController is not equal to secondNavViewController. Objective-C is case sensitive.

So you need to SecondNavViewController instance like:

SecondNavViewController * secondNavViewController = [[SecondNavViewController alloc] ...];
[self.navigationController pushViewController:secondNavViewController animated:YES];
...
