Hi, I'm new to these forums so I apologize for my noobieness. I did as thorough a search as I could, but I couldn't find anyone else with this issue, applogise if this has been covered elsewhere.

I've created a very simple example of my problem. I'm sure I'm missing something but I can't for the life of me figure out what.

I'm creating a UIWebView and adding it to a custom view controller that inherits from UIViewController. When the app loads in the iPad simulator, the uiwebview loads the desired page, but the UIWebView is entirely unresponsive. The webview does not pan or scroll and none of the in page links can be clicked. However, if you change the orientation of the webview suddleny everything works.

Thanks in advance for your help!!

AppDelegate header


#import <UIKit/UIKit.h>
#import "EditorViewController.h"

@interface FixEditorTestAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    EditorViewController *editorView;
}



    @property (nonatomic, retain) IBOutlet UIWindow *window;
    @property (nonatomic, retain) EditorViewController *editorView;

@end

AppDelegate Implementation


#import "FixEditorTestAppDelegate.h"
#import "EditorViewController.h"



@implementation FixEditorTestAppDelegate



@synthesize window;
@synthesize editorView;




- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {   
    NSLog(@"application is loading");
    editorView = [[EditorViewController alloc] init];
    [window addSubview:[editorView view]];
    [window makeKeyAndVisible];
    return YES;
}




- (void)dealloc {
    [window release];
    [editorView release];
    [super dealloc];
}
@end

View Controller header


#import <UIKit/UIKit.h>


@interface EditorViewController : UIViewController <UIWebViewDelegate> {
    UIWebView *webView;
}



@property (nonatomic, retain) UIWebView *webView;




@end

View Controller Implementation


#import "EditorViewController.h"



@implementation EditorViewController
@synthesize webView;



/*
// The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        // Custom initialization
    }
    return self;
}
*/




// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
    NSLog(@"loadView called");

    UIView *curView = [[UIView alloc] init];

    webView = [[UIWebView alloc] init];
    webView.frame = CGRectMake(20, 40, 728, 964);
    webView.delegate = self;
    webView.backgroundColor = [UIColor redColor];

    [curView addSubview: webView];
    self.view = curView;

    [curView release];



}







//Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"viewDidLoad called");
    NSURL *url = [[NSURL alloc] initWithString:@"http://www.nytimes.com"];



    NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
    [webView loadRequest:request];
    [url autorelease];
    [request release];



}



- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Overriden to allow any orientation.
    return YES;
}




- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}




- (void)viewDidUnload {
    webView.delegate = nil;
    [webView release];
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}



- (void)dealloc {
    [super dealloc];
}
