Load a Navigation ViewController from bottom - iphone

Question

I am having four ViewControllers , where the ViewControllers are loaded using the UINavigationController. I am able to switch to every ViewController one by one.
The thing is, since I am using the NavigationController all the ViewControllers are loaded either from the Left or from the Right. But I want to load the ViewController from the Bottom. I know I can use presentModalViewController to present the ViewController from the Bottom. But it is not equivalent to the Navigation Controller because , from the 4th ViewController, If I press one button , I need to come to the 1st ViewController.
How can I present a ViewController from the bottom in the NavigationController ?

Answer 1

Try this:
CATransition *animation = [CATransition animation];
[animation setDuration:2];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromTop];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
SecondView *sObj=[[SecondView alloc] initWithNibName:#"SecondView" bundle:nil];
[self.navigationController pushViewController:sObj animated:YES];
[[sObj.view layer] addAnimation:animation forKey:#"SwitchToView1"];

Use this may this will help you
[UIView beginAnimations:#"Hide Me" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:kAnimationDur];
subScroll.frame = CGRectMake(0,ksubScrollHideY,ksubScrollW,ksubScrollH);
clickPic.frame = CGRectMake(kButtonX,kButtonHiddenY,kButtonW,kButtonH);
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
Happy Coding :)

Answer 3

after you create the viewController, instead of:
[self.navigationController pushViewController:blablabla animated:YES];
do:
[self presentModalViewController:blablabla animated:YES];
and it will come from the bottom.
to go back, just say:
[self dismissViewControllerAnimated:YES];
