Answer 1

It is because you create new view controller which is not in the stack. What you should do is following:
for (UIViewController *vc in self.navigationController.viewControllers) {
if ( [vc isKindOfClass:ViewPage2]){
[self.navigationController popToViewController:vc animated:true];
return; //optional
}
}

Answer 2

ViewPage2 *ptwo;
for (UIViewController *vc in self.navigationController.viewControllers) {
if ([vc isKindOfClass:[ViewPage2 class]]) {
ptwo = (ViewPage2 *)vc;
break;
}
}
[self.navigationController popToViewController:ptwo animated:true];

Answer 3

Here is the simple answer:
NSArray *arr = [self.navigationController viewControllers];
[self.navigationController popToViewController:[arr objectAtIndex:0] animated:YES];
In place of,
[arr objectAtIndex:0]
here you can give index of specified view controller that you need to pop.

Answer 4

You can try doing this
first import the ViewController on which page u want to go.
like
#import ViewController.h
Then u can do the following
instantiate the class
ViewController *controller = [[ViewController alloc ] init];
[self.navigationController pushViewController:controller animated:YES];
or you can do popToViewController too

Answer 5

for (UIViewController *controller in self.navigationController.viewControllers) {
//Do not forget to import YourViewController.h
if ([controller isKindOfClass:[ViewController class]]) {
[self.navigationController popToViewController:controller
animated:YES];
break;
}
}
