It works perfect fine when starting in portrait and also works when you rotate from portrait to landscape and back.

It does not work when starting in landscape. But then it works when you rotate from landscape to portrait and back.

In landscape starting mode, the screen does not respond with any touch where screen coordinateX greater than 768.

What happens in code is, I use status bar orientation to determine original orientation and rotate each view manually. The views display correctly but does not receive touch properly.

Then my root view controller will get called when ipad start rotating with:

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

which will rotate every subviews.

Root controller:

- (void)loadView {
    self.view = [[UIView alloc]init ]; 
    //initialize child views
    [self willRotateToInterfaceOrientation:0 duration:0];    

}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { 
    if ([model isLandscape]) {
        self.view.frame = CGRectMake(0, 0, 1024, 768-80);
    }
    else {
        self.view.frame = CGRectMake(0, 0, 768, 1024-80);
    }
    //rotate child views  
}

My code [model isLandscape] works so I don't need to provide details as to how it works but here are the code anyway:

- (bool)isLandscape {
    if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) 
        return true;
    else 
        return false;
}

-(id) init
{
    [[NSNotificationCenter defaultCenter] addObserver:self   selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];
}

- (void)orientationChanged:(NSNotification *)notification
{
    UIInterfaceOrientation curOrientation = [[UIDevice currentDevice] orientation];
    if (curOrientation == UIDeviceOrientationPortrait ||
        curOrientation == UIDeviceOrientationPortraitUpsideDown ||
        curOrientation == UIDeviceOrientationLandscapeLeft ||
        curOrientation == UIDeviceOrientationLandscapeRight)
    {
        orientation = curOrientation;
        ((AppDelegate*)([UIApplication sharedApplication].delegate)).savedOrientationForRestart = orientation;
        NSLog(@"changed");
    }
}

-(void)validateOrientation { //first time when initializing orientation
    UIInterfaceOrientation curOrientation = [[UIDevice currentDevice] orientation];
    if (curOrientation != UIDeviceOrientationPortrait &&
        curOrientation != UIDeviceOrientationPortraitUpsideDown &&
        curOrientation != UIDeviceOrientationLandscapeLeft &&
        curOrientation != UIDeviceOrientationLandscapeRight)
    {
        orientation = [[UIApplication sharedApplication] statusBarOrientation];
    }

}
