AS i remember, you cannot rotate the SDK's UITabBar controller. You chold make your own tabbar, inherint it from UITabBar and there return YES in shouldAutoRotate method.

#import <UIKit/UIKit.h>    
  @interface MainTabBarController : UITabBarController{
  }    
 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
@end

this is an .h file

#import "MainTabBarController.h"
@implementation MainTabBarController
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    return YES;
} 
@end

You just have to change class of your tabbar from UITabBarController to MainTabBarController

Here's an extension to UITabBarController that delegates calls to shouldAutorotateToInterfaceOrientation to the currently selected child controller. Using this extension, you don't need to subclass UITabBarController anymore and you can use shouldAutorotateToInterfaceOrientation in your controllers like one would expect.

UITabBarController+Autorotate.h:

#import <UIKit/UIKit.h>

@interface UITabBarController (Autorotate)
@end

UITabBarController+Autorotate.m:

#import "UITabBarController+Autorotate.h"

@implementation UITabBarController (Autorotate)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    UIViewController *controller = self.selectedViewController;
    if ([controller isKindOfClass:[UINavigationController class]])
        controller = [(UINavigationController *)controller visibleViewController];
    return [controller shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

@end

Maybe try editing the info.plist and also add your supported orientations there?

Select your project --> Select your target --> Info --> Supported interface orientations and click on the plus sign 4 times to support these orientations:

Item 0   Landscape (left home button)
Item 1   Landscape (right home button)
Item 2   Portrait (top home button)
Item 3   Portrait (bottom home button)

Hope it helps!
