Pushed View controller is not found in the navigation stack?

Question

I have an application in which i am pushing a testviewcontroller from a viewcontroller.testviewcontroller has a back button and a yes button.when pressing the back button i am going back to the previous by using

[self.navigationController popViewControllerAnimated:YES];

when pressing the Yes button i am pushing another view controller using

 GettingViewController *get  =[[GettingViewController alloc] initWithNibName:@"GettingViewController" bundle:nil];
 [self.navigationController pushViewController:get animated:NO];

this are all working fine.in the rewardsget when pressing a button i am poping back to testviewcontroller.using this `

for (TestViewController*vc in [self.navigationController viewControllers]) {
            if ([vc isKindOfClass: [TestViewController class]]){

                 [[self navigationController] popToViewController:vc animated:YES];
            }
        }
`

but when i am pressing the back button in that view it needs to go to my new pushed view controller ie rewardsget.But when i am printing the view controllers it is not present in the stack.so it is again going back to the first pushed viewcontroller,not the latest.can anybody help me on this?

Answer 1

It sounds like you have multiple instances of TestViewController in your stack. To get to the correct one just pass a pointer to TestViewController to your GettingViewController, you may want to have a property:

@property (nonatomic, assign) TestViewController* testViewController;

When you're ready to go back to your TestViewController call [self.navigationController popToViewController: self.testViewController animated: YES]; .

That said, it sounds like your navigation flow may need some more thought. On iOS a hub-and-spoke navigation flow is the most natural.

Answer 2

in your for loop you go through all the viewControllers but already pretend that these are TestViewController (TestViewController*vc ...). Of course the first one you are looking for isKindOfClass TestViewController then!

Try changing this to UIViewController*vc!
