iOS WebView in Landscape

I am trying to integrate a WebView into my Unity project. I will also need to get call backs from the web pages where the javascript in the web page can make calls into Unity.

I have a great WebView plugin sample that I have adapted for my needs the works really well except for a single problem.

My app starts in Landscape and will always be in landscape. When I browse to the web page that we are using for our back end the page comes up just fine. I tap in the text field and the keyboard comes up. Everything is still great. I can hit the next and previous and still good.

The problem is when I dismiss the keyboard the web page width shrinks to the width it would be if the page were in portrait mode.

I want to keep this as lite weight as possible. I looked at uWebKit and Prime31. Neither of those allow for the web page javascript to call back into Unity like mine does, so I can't use those. Plus they are heavy and expensive. What I have is so very close and lite weight if I could just solve this problem I would be golden. I just don't know enough about Obj-c to solve it on my own.

There is more to this class than I am showing here. I am just showing the stuff related to init, changing to landscape and such along with the dealloc in case I am forgetting something there.

The only problem is when the keyboard goes away the width changes to portrait width (it is still oriented correctly however).

I will now show the code I am using:

 #import <UIKit/UIKit.h>
 
 extern UIViewController *UnityGetGLViewController();
 extern "C" void UnitySendMessage(const char *, const char *, const char *);
 extern void UnitySetAudioSessionActive(bool active);
 extern void UnityPause(bool pause);
 
 @interface WebViewPlugin : NSObject<UIWebViewDelegate>
 {
     UIWindow *overlayWindow;
     UIActivityIndicatorView *spinner;
     
     UIWebView *webView;
     NSString *gameObjectName;
     
     CGRect orientedFrame;
 }
 @end
 
 @implementation WebViewPlugin
 
 - (id)initWithGameObjectName:(const char *)gameObjectName_
 {
     self = [super init];
     
     CGRect bounds = [[UIScreen mainScreen] bounds];
     orientedFrame = CGRectMake(bounds.origin.x, bounds.origin.y, bounds.size.height, bounds.size.width);
     
     overlayWindow = [[UIWindow alloc] initWithFrame:bounds];
     
     float angle = M_PI_2;
     CGAffineTransform transform = CGAffineTransformMakeRotation(angle);
     [overlayWindow setTransform:transform];
     
     webView = [[UIWebView alloc] initWithFrame:orientedFrame];
     webView.delegate = self;
     webView.hidden = NO;
     webView.center = overlayWindow.center;
     
     [overlayWindow addSubview:webView];
     
     [overlayWindow makeKeyAndVisible];
     
     gameObjectName = [[NSString stringWithUTF8String:gameObjectName_] retain];
     
     return self;
 }
 
 - (void)dealloc
 {
     [webView removeFromSuperview];
     [webView release];
     [overlayWindow release];
     overlayWindow = nil;
     [gameObjectName release];
     [super dealloc];
 }
