go from one UIViewController to another without using navigation (segue) iOS 6

Question

In my program I have UIViewController which has two buttons, one is "signIN" and other is "register". When "Sign IN" button is pressed, it should go to next viewController without using segue and when "register" button is pressed, it should move to next UIViewController by using segue.

Answer 1

Use pushViewController:

- (void)didPressButton:(UIButton *)sender
{
    [self.navigationController pushViewController:nextViewController animated:YES];
}

Answer 2

Depending on the way you wish to present your view controller you should choose between:

1. Pushing the new view controller onto the current Navigation controller [self.navigationController pushViewController:someOtherViewController animated:YES];

2. Present the new view controller modally [self presentModalViewController:someOtherViewController animated:YES completion:nil];

3. Manually adding the new view controller onto the current view controller: [self addChildViewController:childController]; childController.view.frame = view.bounds; [view addSubview:childController.view]; [childController didMoveToParentViewController:self]; // To remove: [self willMoveToParentViewController:nil]; [self.view removeFromSuperview]; [self removeFromParentViewController];

Answer 3

[[self navigationController] pushViewController:yourPushedViewController animated:YES];
