Solution

  • Case 1 : Unwind Segue

    This will work perfect according to your situation:

    iOS Unwind Segue

    Unwind Segues give you a way to “unwind” the navigation stack and specify a destination to go back to.

    Case 2 : PopToRootViewController

    If you Parent view is also your Root view controller, then you can easily get back using popToRootViewControllerAnimated:YES.

    Create own back button add it to navigation bar with method backButtonTouch.

    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", nil) style:UIBarButtonItemStyleDone target:self action:@selector(backButtonTouch:)];

    Add above code into viewDidLoad.

    -(void)backButtonTouch:(id)sender{
    [self.navigationController popToRootViewControllerAnimated:YES];
}
