How to load local html file into UIWebView

EDIT 2016-05-27 - loadRequest exposes "a universal Cross-Site Scripting vulnerability." Make sure you own every single asset that you load. If you load a bad script, it can load anything it wants.

If you need relative links to work locally, use this:

NSURL *url = [[NSBundle mainBundle] URLForResource:@"my" withExtension:@"html"];
[webView loadRequest:[NSURLRequest requestWithURL:url]];

The bundle will search all subdirectories of the project to find my.html. (the directory structure gets flattened at build time)

If my.html has the tag <img src="some.png">, the webView will load some.png from your project.

probably it is better to use NSString and load html document as follows:

Objective-C

NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL: [[NSBundle mainBundle] bundleURL]];

Swift

let htmlFile = NSBundle.mainBundle().pathForResource("fileName", ofType: "html")
let html = try? String(contentsOfFile: htmlFile!, encoding: NSUTF8StringEncoding)
webView.loadHTMLString(html!, baseURL: nil) 

Swift 3 has few changes:

let htmlFile = Bundle.main.path(forResource: "intro", ofType: "html")
let html = try? String(contentsOfFile: htmlFile!, encoding: String.Encoding.utf8)
webView.loadHTMLString(html!, baseURL: nil)

Did you try?

Also check that the resource was found by pathForResource:ofType:inDirectory call.

by this you can load html file which is in your project Assets(bundle) to webView.

 UIWebView *web = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
    [web loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                pathForResource:@"test" ofType:@"html"]isDirectory:NO]]];

may be this is useful to you.
