Call to UIWebView crashing my app in iOS - objective-c

Question

I have a WebView in my storyboard. I created an outlet property to that webview in my view controller file. Then in my code in I'm calling it like this:
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"news1" ofType:#"html" inDirectory:#"/HTML"]];
[self.webView loadRequest:[NSURLRequest requestWithURL:url]];
}
The problem is my app is crashing when I run this and I don't really know why. I get this error, but I need help deciphering what the issue is.

Answer 1

The HTML file isn't in your bundle or isn't at the path specified. Check the case of the file and folder name. If you build/run in the simulator, you can look through the bundle inside of ~/Library/Application Support/iPhone Simulator/7.1/Applications.

Answer 2

Don't use loadRequest if you want to load html locally. use this
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL:nil];
