iOS无法将PDF显示在UIWebView中

Question

I'm having issues displaying a PDF in a UIWebView - something that should be really trivial (even for me beginner level). However I'm not seeing anything.

I have a UIWebView correctly connected as an IBOutlet, then in the viewDidLoad, i have the following code:

NSURL *targetURL = [NSURL URLWithString:@"/Users/tom........../PDF_6.pdf"];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[_pdfWebView loadRequest:request];

Any ideas what I'm doing wrong??

Thanks.

(Apologies if this is a really duplicated question i just can't find the answer).

Answer 1

Since it seems you want to load the PDF from a file, you need to create a file URL:

NSURL *targetURL = [NSURL fileURLWithPath:@"/Users/tom........../PDF_6.pdf"];

BTW - that path is only going to work in the simulator, not on a real iOS device.
