Answer 1

in viewWillAppear:Animated of your first controller, call

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];

And of course, set up the shouldAutoRotateToInterfaceOrientation to return YES only on UIInterfaceOrientationPortrait.

Answer 2

in viewWillAppear:Animated of your first controller, call [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];
