Not possible with UINavigationController; you'll have to build your own navigation controller (should be pretty easy) that incorporates a UIPanGestureRecognizer.

EDIT for iOS 7: You'll probably want to use a UIScreenEdgePanGestureRecognizer.

Gesture recognizers have action methods just like buttons. Just put this in the action method:

NextViewController *next = [[NextViewController alloc] init ....];
[self.navigationController pushViewController:next animated:YES];

I know that. But I want the ViewController can move with my finger – lixiaoyu Mar 21 '13 at 06:31
@lixiaoyu, well, then that's not a "push" or "pop" in the usual sense, and you need to do it with a pan rather than a swipe, because a swipe is a discrete gesture. – rdelmar Mar 21 '13 at 06:37

Read about gesture recognizers. You can create them and add it on objects. For example

UILongPressGestureRecognizer *longTap = [[UILongPressGestureRecognizer alloc] 
                                         initWithTarget:self 
                                         action:@selector(longPress:)];
longTap.minimumPressDuration = 1.0;
[cell addGestureRecognizer:longTap];

Here I have created LongPress recognizer and added it on my cell. If I will longpress(1.0 sec) on my cell, it will call selector(longPress:). In long press I can make any code.

-(void)longPress : (UILongPressGestureRecognizer *)rec {
   if (rec.state == UIGestureRecognizerStateBegan) {
   NSLog (@"I've longPressed");
   }
}

You can use different recognizers by the same way.

About push and pop. They are methods of Navigation controller. Push - goes forward, on controller which you shows him;

NextController *goNext = [[NextViewController alloc] init];
[self.navigationController pushViewController:goNext animated:YES];

it will go to the NextController. Pop - backs to the previous controller.

Here you don't need to show the previous controller. Just say to navController back

 [self.navigationController popViewControllerAnimated:YES];
