Path is not working
<pre><code>NSBundle *thisBundleb = [NSBundle mainBundle];

pathb = [thisBundleb pathForResource:[a3 objectAtIndex:0] ofType:@"html"];

NSURL   *instructionsURLb = [[NSURL alloc] initFileURLWithPath:pathb];
[webView loadRequest:[NSURLRequest requestWithURL:instructionsURLb]];       
</code></pre>

<p>value of [a3 objectAtIndex:0]=index but when i pass like this i am getting
 <strong>* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '<em></strong> -[NSURL initFileURLWithPath:]: nil string parameter'</em>*</p>

<p>What I am doing wrong?</p>
