How do I switch a new view controller in iOS development?

Question

I am trying to write an IBAction to switch view controllers for my iPhone application:

-(IBAction)changeToView2:(id)sender 
{
    if (self.view2 == nil)
    {
        view2 = [[UIViewController alloc] initWithNibName:@"View2Controller" bundle:[NSBundle mainBundle]];
    }
    self.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentedViewController: view2 animated:YES];
}

However, I am getting a build error noting that no interface declares "presentedViewController:animated:". Why?

Changing this to "presentViewController:animated:" produces the same error.

Interestingly, XCode still notes that "no visible @interface declares the selector presentViewController:animated:" if I use that instead. Also, when I begin typing the function name, auto-complete does not mention this function name. — Justin Copeland

Also, what is 'completion:<#^(void)completion#>'? It seems as if this function has a third argument. — Justin Copeland

Is this code part of a view controller class? Or a view? Is the project navigation based? i.e. is there a navigationController? — Damo

The method is presentViewController:animated:completion:, not presentedViewController:animated:

Thank you, but XCode still notes that "no visible @interface declares the selector presentViewController:animated:".

Instead of

[self presentedViewController: view2 animated:YES];

try

[self presentViewController: view2 animated:YES];

Is "self" a UIViewController?

Can you go to your header file and post the interface here?

Try this your edited code.I think this will be helpful for you.

-(IBAction)changeToView2:(id)sender 
{
if (self.view2 == nil)
{
    view2 = [[UIViewController alloc] initWithNibName:@"View2Controller" bundle:nil];
}
self.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentedViewController: view2 animated:YES];
}
