Are you check out your pdf file in your project?

I test a following code. no problem.

please check your chapter.pdf file in your project. the point is relative path.

Must be case sensitive. “Chapter” / “chapter” is not equalString.

NSLog(@"path:%@",[[NSBundle mainBundle] pathForResource:@"chapter" ofType:@"pdf"]);


console:
    /var/mobile/Applications/72AFA069-D83E-469A-A687-AEAFDB0B4D97/TableViewTest.app/chapter.pdf

NSLog(@"path:%@",[[NSBundle mainBundle] pathForResource:@"Chapter" ofType:@"pdf"]);


console:
    (null)

self.myWebView = [[[UIWebView alloc] initWithFrame:webFrame] autorelease];
self.myWebView.backgroundColor = [UIColor whiteColor];
self.myWebView.scalesPageToFit = YES;
self.myWebView.delegate = self;
[self.view addSubview:self.myWebView];
[self.myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"chapter" ofType:@"pdf"]]]];

In your project folder name will disappear in a actual iPhone bundle.
You have created a folder called Resource-Common, but eventually disappears in NSBundle.

See the image below. Both are integrated. folder name in the project is only just visible folder in xcode.

If you want all pdf file list in NSBundle. try to following code.

NSArray *pdfCollection = [[NSBundle mainBundle] pathsForResourcesOfType:@"pdf" inDirectory:nil];
