Question

我三合会点击PDF文件中的URL。和UI文件中打开的PDF文件，但我无法点击URL。

任何人都告诉我如何打开PDF文件中的URL。

UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 20, 320, 460)];
NSURL *targetURL = [NSURL URLWithString:@"http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf"];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[webView loadRequest:request];

[self.view addSubview:webView];

Answer 1

在你的webView委托方法中，首先从PDF中检测网址，然后在webview等中打开。我使用了以下方法来做到这一点，可能会帮助你：

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
       NSURL *requestURL = [[ request URL] retain];

       if (([[requestURL scheme] isEqualToString: @"http"] || [[requestURL scheme] isEqualToString: @"https"]) && (navigationType == UIWebViewNavigationTypeLinkClicked)) 
       {
          // Your method when tap on url found in PDF
       }

  }

如果您在本地存储中有PDF文件

NSString *html = [NSString stringWithContentsOfFile:path1 encoding:NSUTF8StringEncoding error:nil];
[self.webView loadHTMLString:html baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]bundlePath]]];

如果您可以从Internet访问文件

- (void) loadRemotePdf
{
       CGRect rect = [[UIScreen mainScreen] bounds];
       CGSize screenSize = rect.size;

       UIWebView *myWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,screenSize.width,screenSize.height)];
       webView.autoresizesSubviews = YES;
       webView.autoresizingMask=(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth);

       NSURL *myUrl = [NSURL URLWithString:@"http://www.mysite.com/test.pdf"];
       NSURLRequest *myRequest = [NSURLRequest requestWithURL:myUrl];

       [webView loadRequest:myRequest];

       [window addSubview: myWebView];
       [myWebView release];

}
