Answer 1

type these two methods in your login ViewController

(BOOL)shouldAutorotate { return YES;
}

(NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown); }

and

(BOOL)shouldAutorotate { return YES;
}

(NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft); }

in your childcontroller

required to add category autorotation subclassed navigation controller which would call topcontroller shouldautorotate and supported interface orientation.

#import "UINavigationController+Autorotation.h"

@implementation UINavigationController (Autorotation)
-(BOOL)shouldAutorotate
{
for (UIViewController * viewController in self.viewControllers) {
    if (![viewController isEqual:self.topViewController]) {
        [viewController shouldAutorotate];
    }
}

return [self.topViewController shouldAutorotate];

}

-(NSUInteger)supportedInterfaceOrientations
{
for (UIViewController * viewController in self.viewControllers) {
    if (![viewController isEqual:self.topViewController]) {
        [viewController supportedInterfaceOrientations];
    }
}

return [self.topViewController supportedInterfaceOrientations];

}
