Storyboard - Workflow for a corner-based game

Question

I am creating a turn-based game and would like to know the right process for my workflow. I currently have the following:

Home View controller (which has UITableView)
Click on a line from section 1> Download a UINavigationControllerusing path 1
Click on a line from section 2> Download a UINavigationControllerusing path 2

As an example:
path 1 - play turn
2; guess your move

Each path has about 4-5 UIViewControllersloaded into the navigation controller.

Now I am at the stage when one path 2 is completed, the user must also play a turn (i.e. go through path 2, then path 1).

What is the correct way to do this? should I create a segue from the last controller in path 2> leading to path 1. The problem is that in path 2 there is UIViewControllerone that has UIImageViewa large image and it will freeze in memory. Ideally, it is cleared as such before the user starts path 1 (after completion of path 2).

, , . ViewController Path2. UINavigationController. , .

- (IBAction)completeButtonPressed:(id)sender {
    NSLog(@"complete button pressed");

    Path2ViewController *path2StartVC = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"Path21VC"];

    [self.navigationController setViewControllers:[NSArray arrayWithObject:path2StartVC] animated:YES];
