this works very well and fast but it does not load images if I give baseurl instead of nil. It takes few seconds to load.

NSURL *myUrl = [[NSURL alloc] initFileURLWithPath:self.contentPath];
//NSLog(@”Content url is %@”,myUrl);

NSString *string = [[NSString alloc]initWithContentsOfFile:self.contentPath encoding:NSASCIIStringEncoding error:nil];
[contentDisplay loadHTMLString:string baseURL:nil]; //here nil if replaced by myUrl webView takes time to load. Any help ?
[string release];
[myUrl release];

Hi All. If you are still interested in this topic I prepare an example in my blog and pointed the links to the blogs I used to build a page with local resources using UIWebView.

I hope this will save your time. I wm will be happy if you share your opinion on my blog.

@pramod: There seems to be a lot of confusion surrounding UIWebView and caching on the iPhone. I have not done any testing myself so unfortunately I cannot add any clarity. But this Stack Overflow entry seems to have the best overview of the situation.

Does UIWebView cache the images loaded using img src tag. if so where do it cache in the iPhone and what is the time it keeps its content into its cache.

Just found what appears to be a good workaround for loading CSS!

@Joe: Interesting, I was not aware of this change. Let me do some more thinking and see what else I can come up with.

@Nick: No can do. Relative URLs do not work per the 3.0 SDK Release Notes (when using loadHTMLString:baseURL:). I even tried the Data variant. No dice.

@Dan: You can refer to images on your web page by an absolute URL, and images in your bundle by a relative URL (the image name).

But wait a sec – that IS what I’m doing. baseURL _is_ using a file scheme. Ugh.
