Orientation change in ExpanderDemo

[Quamber]

I just started checking AQGridView and new to iOS too in the source example ExpanderDemo the orientation is working fine for the first View but as i click any cell and next upcomming AQGridView does not effect View on GridView.

ExpandingGridViewController *controller = [[ExpandingGridViewController alloc] init];
controller.gridView.frame = self.gridView.frame;
[self.gridView setHidden:YES];
[self.view.superview addSubview: controller.gridView];
[controller expandCellsFromRect: expandFromRect ofView: cell];
[controller viewDidAppear: NO];

On the other hand if i present the view controller to second it works fine with the orientation but losses the Animation for Expansion; which i don't want to loose. What should i do?

ExpandingGridViewController *controller = [[ExpandingGridViewController alloc] init];
[self presentViewController:controller animated:NO completion:nil];
