I have just had problems with the embedded reader view and read that a call to setNeedsLayout was missing on rotation, not sure if it will help someone but here is what fixed my problems

- (void) willRotateToInterfaceOrientation: (UIInterfaceOrientation) orient duration:     (NSTimeInterval) duration
{
    [self.readerView willRotateToInterfaceOrientation:orient  duration:duration];
    [self.readerView setNeedsLayout];
}

Works fine for me. Our iPad app supports only Landscape orientation:

// ADD: present a barcode reader that scans from the camera feed
ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
ScanOverlay overlayController = [[ScanOverlay alloc] initWithNibName:@"ScanOverlay" bundle:nil];
reader.cameraOverlayView = overlayController.view;
ZBarImageScanner *scanner = reader.scanner;
// TODO: (optional) additional reader configuration here
reader.supportedOrientationsMask = UIInterfaceOrientationMaskLandscape;
reader.wantsFullScreenLayout = YES;
reader.showsZBarControls = NO;  //If we don't set this to NO, the overlay may not display at all
reader.tracksSymbols = YES;
[overlayController willRotateToInterfaceOrientation:YES duration:0.5];

// ADD: present a barcode reader that scans from the camera feed

// EXAMPLE: disable rarely used I2/5 to improve performance
[scanner setSymbology: ZBAR_I25
               config: ZBAR_CFG_ENABLE
                   to: 0];

//Show the scanner view    
if([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
    [self presentViewController:reader animated:YES completion:^(void){}];
} else if([self respondsToSelector:@selector(presentModalViewController:animated:)]) {
    [self presentModalViewController:reader animated:YES];
} else {
    NSLog(@"Error! Can't present the View Controller");
}
