should we need to release viewcontroller's object after pushing into navigation controller?

Question

here is sample code.

if(MyPageViewControllerObj==nil)
 {
  MyPageViewController *vController = [[MyPageViewController alloc] initWithNibName:@"MyPageView" bundle:[NSBundle mainBundle]];
  self.MyPageViewControllerObj=vController;
  [vController release];
  noOfWrongAnswers=0;
  noOfRightAnswers=0;
 }
 MyPageViewControllerObj.sessionid=sessionid;
 MyPageViewControllerObj.categoryID = categoryId;
 MyPageViewControllerObj.flashcardIdforcount = flashcardid;
 MyPageViewControllerObj.categoryType=categoryType;
 MyPageViewControllerObj.indexViewControllerobj=self;
 [self.navigationController pushViewController:MyPageViewControllerObj animated:YES];

do i need to write this line **[MyPageViewControllerObj release]**

after pushing it into navigation controller.and also in dealloc method...

Answer 1

Yes, you should to release your MyPageViewControllerObj as the UINavigationController retains it. It does not need to be in the -dealloc method.
