Display a local file in a UIWebView

[jdegrace]

Is is possible to display a local file from the mainBundle in a UIWebView? For example, a PDF file.

Thanks!

I don't see why not as long as it's either a resource in your app, a url to the pdf or something you streamed from the web and downloaded to your apps directory... just point the UIWebView to the file.. should load up just fine.

I thought so, too. I tried the following, but I think I'm probably doing something wrong because it doesn't display anything.

- (void)viewDidLoad {

NSString *pdfPath = [[NSBundle mainBundle] pathForResource:@"EX" ofType:@"pdf"];
NSURL *url = [NSURL URLWithStringdfPath];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[myWebView loadRequest:urlRequest];

}

I think that UIWebView is very trimmed version of the Safari. It doesn't even recognize or can't handle new window links... or javascript open window script

I have the same problem - nothing is displayed. What's wrong with this code?

NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"];

NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];

If I replace urlAddress with this, it works:
//NSString *urlAddress = @"http://www.google.com";

To use a local resource file in a web view you need to use NSURL fileURLWithPath, not NSURL URLWithString.

NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"];

NSURL *url = [NSURL fileURLWithPath:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];

it also helps to set the BaseURL if you want to embed local images into the UIWebView.

#define BASEURL [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]]

thank you, that worked.

What's a simple way to determine if a file is local or remote?

I'm saving the request.URL from webView:webView shouldStartLoadWithRequest: navigationType:

and I don't want it to display a URL if it's a local file.

I just tested this out, and the zooming is extremely slow - it jams for 10 seconds everytime you zoom until the text and images are in focus. Very frustrating. Is there any better way to display a PDF?

I used the code from RickMaddy, put it in the viewDidLoad function, and linked it up to an -(IBAction).

When the 4 page 700KB PDF opens (encoded by Adobe Acrobat 8.1 Paper Capture Plug-in), or any other PDF I have in my bundle, it opens with blank pages and a black column on the right.

Is this an encoding problem or have I done something wrong?

I have this same problem. I have a PDF file I want to load, I have tried in the WebView but I could never get it to work; but as you guys stated it loads very slow. I have also tried to save the PDF as a PNG and display it that way, no go.

I can load it just from the website the PDF is located, but I want it to be available for users offline.

Has anyone found a successful solution to this problem? I'd greatly appreciate it!!
