Question

If my iPad is in Landscape mode and presentModalViewController is called the view automatically turns into portrait mode. Any solutions?

UIViewController * start = [[UIViewController alloc]initWithNibName:@"SecondView" bundle:nil];
start.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
start.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:start animated:YES];

In SecondView I’ve already added:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}

Answer 1

The problem is your sample code is creating UIViewController instead of your actual derived class. In other words instead you should be creating your controller like this:

SecondViewController *start = [[SecondViewController alloc]initWithNibName:@"SecondView" bundle:nil];

I’m assuming your view controller class is called “SecondViewController” because you were loading a nib by a similar name.

If you don’t provide the right instance there is no way your delegate methods can be called.
