UIWebView back button not getting enabled

Question

In my application I have a UIWebView in which I need to add browser like functionality(user can goBack,Forward or reload the page). To achieve this I have used the code for this tutorial.

In my code I have only one change in viewDidLoad:

I am loading data from a local html file like this:

NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"File name" ofType:@"html" inDirectory:NO];
NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile];
[self.webView loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@""]];

instead of:

NSURL* url = [NSURL URLWithString:@"http://iosdeveloperzone.com"];
NSURLRequest* request = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];

After loading initial html file if I am making any click on that page than the back button should get enabled, instead of its getting enabled after second url click and so that I am not able to go back to the original home page.

Please help me with this.

Thanks.

I got an answer. It's because you load data into the webView without loadRequest. If you load data into webView as a string, then it won't have any url to go back or load the old page. So it won't store the data you given to the webView. For that, you need to provide the url as like this.

[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"File name" ofType:@"html"] isDirectory:NO]]];
