ios develops the navigationController pushViewController method of multiple jumps back to the top to return to a specified level of implementation

Returns a specified vc with the following (located via index)

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:2] animated:YES];
 Or (by class Positioning) 
for (UIViewController *controller in self.navigationController.viewControllers) {
if ([controller isKindOfClass:[ You're going to jump to Controller class]]) {
[self.navigationController popToViewController:controller animated:YES];
}
}
