   It seems like this change on iOS8 is the reason.

   This is a quick fix for iOS8 only app.

       case UIInterfaceOrientationLandscapeLeft:
           rotateAngle = -M_PI/2.0f;
           newCenter = CGPointMake([UIScreen mainScreen].bounds.size.height/2, [UIScreen mainScreen].bounds.size.width/2);
           break;
       case UIInterfaceOrientationLandscapeRight:
           rotateAngle = M_PI/2.0f;
           newCenter = CGPointMake([UIScreen mainScreen].bounds.size.height/2, [UIScreen mainScreen].bounds.size.width/2);
           break;

   This is a quick fir fox iOS9 too.

   - (void)positionHUD:(NSNotification*)notification {

           orientationFrame.size.height = temp;
       }
