Objective C: View PDF File Link With UIWebView - ios

Question

I am trying to view a PDF file from a server but I only get a view in black and doesn't contain anything. Here's my code:
pdfViewer = [[UIWebView alloc] initWithFrame:CGRectMake(0, 44, 768, 949)];
pdfViewer.backgroundColor = [UIColor whiteColor];
pdfViewer.delegate = self;
[sgContainer addSubview:pdfViewer];
chatSpinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
chatSpinner.frame = CGRectMake(334, 462, 100, 100);
[pdfViewer addSubview:chatSpinner];
NSString *httpSource = #"http://www.mywebsite.com/folder/subfolder/file.pdf";
NSURL *fullUrl = [NSURL URLWithString:httpSource];
NSURLRequest *httpRequest = [NSURLRequest requestWithURL:fullUrl];
[pdfViewer loadRequest:httpRequest];

If you are trying to display a PDF file residing on a server somewhere, you can simple load it to your web view directly:
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
NSURL *targetURL = [NSURL URLWithString:#"http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIWebView_Class/UIWebView_Class.pdf"];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];
[self.view addSubview:webView];
[webView release];
Or if you have a PDF file bundled with your application (in this example named "document.pdf"):
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
NSString *path = [[NSBundle mainBundle] pathForResource:#"document" ofType:#"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];
[self.view addSubview:webView];
[webView release];
Let me know if you face any problem.
