Answer 1

 - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

}

-(void)viewWillLayoutSubviews
{
if([self interfaceOrientation] == UIInterfaceOrientationPortrait||[self interfaceOrientation] ==UIInterfaceOrientationPortraitUpsideDown)
    {
       if (screenBounds.size.height == 568)
        {
          //set the frames for 4"(IOS6) screen here
         }
        else

        {
         ////set the frames for 3.5"(IOS5/IOS6) screen here
        }

}
        else if ([self interfaceOrientation] == UIInterfaceOrientationLandscapeLeft||[self interfaceOrientation] == UIInterfaceOrientationLandscapeRight)
        {
         if (screenBounds.size.height == 568)
        {
          //set the frames for 4"(IOS6) screen here
         }
        else

        {
         ////set the frames for 3.5"(IOS5/IOS6) screen here
        }


    }
//it is for IOS5
 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
    {
     return YES;
    }

-(void)viewWillLayoutSubviews this method will call for ios5/ios6. this code is usefull to both ios6/ios5/ios6 with 3.5" screen/4" screen with ios6.
