How to Dismiss Model View Controller before push?

Question

Currently my scenario like this ,

View Controller(VC1)  -->  Push Segue --> View Controller(VC2)
          |                                   ^ 
          | Model Segue                       |
          |                                   | Push Segue
          |-----> View Controller(VC3)  ------|

Now in VC3 when i push in to VC2 i want to dismiss VC3 view Controller and on after VC2 back button it should be VC1's back view controller i want to pop VC3

What i want is i want to remove VC3 when i push the VC2 from VC3 when we back then it VC1 should appear

Check Example

I have done like this can anyone help me out

View Controller (VC3) :

- (void)callWebservice {

   [self dismissViewControllerAnimated:YES completion:^{

         [self performSegueWithIdentifier:@"showVC2" sender:self];
   }];

}

Thanks in advance

I think you are looking for https://stackoverflow.com/a/21415225/1320305 if you are using segue, to do this manually try following:

you can try this

 // locally store the navigation controller since
 // self.navigationController will be nil once we are popped
 UINavigationController *navController = self.navigationController;

 // retain ourselves so that the controller will still exist once it's popped off
 [[self retain] autorelease];

 // Pop this controller and replace with another
 [navController popViewControllerAnimated:NO];//not to see pop

 [navController pushViewController:aViewController animated:YES];
//to see push or u can change it to not to see.

OR try this

UIViewController *newVC = [[UIViewController alloc] init]; // Replace the current view controller 
NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:[[self navigationController] viewControllers]];
[viewControllers removeLastObject]; 
[viewControllers addObject:newVC]; 
[[self navigationController] setViewControllers:viewControllers animated:YES];

i think in your callWebservice method call. remove current code and place any one of the option. – a4arpan Dec 10 '15 at 09:18

I think you can implement in that way:

when you at screen 3 you want push screen 2. You will dismiss screen 3 and call a delegate back screen 1.
And from screen1 you will push view to screen2.

You can see my demo for my idea: Demo Pushview Swift
