iOS 4.2 Default.png loads then 1 sec of solid gray then my UIWebView appears

How do I make my app seamless from the default.png to my App? Should I load it somewhere else? FYI I only have an iPod Touch 2nd Gen for testing running 4.2.1(8C148) The 4.2 simulator does the same thing. 4.3 simulator works fine.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictio开发者_如何学Gonary *)launchOptions {  
    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:YES]]];
    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    [self.window addSubview:viewController.view];
    [self.window makeKeyAndVisible];

    return YES; 
}

What is happening it is taking a few seconds before UIWebView fully loads its content. So whilst it is loading, you are seeing the background color of the web view. If you don't want the blank screen, I would advise showing an activity indicator, to show that something is happening.

Alternatively, set the webViews delegate as your self and only perform [self.window makeKeyAndVisible] in the webView' delegate message named `webView:didFinishLoad‘

The latter method is unadvisedly though, as your effectively delaying the start of your app for several seconds.

In viewDidLoad,

webView.delegate = self;

Now in a separate method, called -(void)webViewdidFinishLoad:(UIWebView *)theWebView

[imageView removeFromSuperview]
[imageView release]
