iPhone：我们可以使用UIWebView打开pdf文件吗？
我们可以从UIWebView打开PDF文件吗？
如果有任何人已经实施了，那么请帮助我。
任何代码片段或任何网站链接将有所帮助。
是的，这可以通过UIWebView来完成。
如果您试图显示驻留在某个服务器上的PDF文件，则可以直接将其加载到Web视图中：
Objective-C的
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)]; NSURL *targetURL = [NSURL URLWithString:@"https://www.example.com/document.pdf"]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; [webView loadRequest:request]; [self.view addSubview:webView]; 迅速
let webView = UIWebView(frame: CGRect(x: 10, y: 10, width: 200, height: 200)) let targetURL = NSURL(string: "https://www.example.com/document.pdf")! // This value is force-unwrapped for the sake of a compact example, do not do this in your code let request = NSURLRequest(URL: targetURL) webView.loadRequest(request) view.addSubview(webView)
或者，如果您的应用程序捆绑了PDF文件（在本例中名为“document.pdf”）：
Objective-C的
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)]; NSURL *targetURL = [[NSBundle mainBundle] URLForResource:@"document" withExtension:@"pdf"]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; [webView loadRequest:request]; [self.view addSubview:webView];
迅速
let webView = UIWebView(frame: CGRect(x: 10, y: 10, width: 200, height: 200)) let targetURL = NSBundle.mainBundle().URLForResource("document", withExtension: "pdf")! // This value is force-unwrapped for the sake of a compact example, do not do this in your code let request = NSURLRequest(URL: targetURL) webView.loadRequest(request) view.addSubview(webView)

在webview中使用这个打开的pdf文件
NSString *path = [[NSBundle mainBundle] pathForResource:@"mypdf" ofType:@"pdf"]; NSURL *targetURL = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; UIWebView *webView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 300, 300)]; [[webView scrollView] setContentOffset:CGPointMake(0,500) animated:YES]; [webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"window.scrollTo(0.0, 50.0)"]]; [webView loadRequest:request]; [self.view addSubview:webView]; [webView release];
Webviews也可以使用loadData方法加载pdf，如果您将其作为NSData获取：
[self.webView loadData:self.pdfData MIMEType:@"application/pdf" textEncodingName:@"UTF-8" baseURL:nil];
NSString *folderName=[NSString stringWithFormat:@"/documents/%@",[tempDictLitrature objectForKey:@"folder"]]; NSString *fileName=[tempDictLitrature objectForKey:@"name"]; [self.navigationItem setTitle:fileName]; NSString *type=[tempDictLitrature objectForKey:@"type"]; NSString *path=[[NSBundle mainBundle]pathForResource:fileName ofType:type inDirectory:folderName]; NSURL *targetURL = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; webView=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 1024, 730)]; [webView setBackgroundColor:[UIColor lightGrayColor]]; webView.scalesPageToFit = YES; [[webView scrollView] setContentOffset:CGPointZero animated:YES]; [webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"window.scrollTo(0.0, 50.0)"]]; [webView loadRequest:request]; [self.view addSubview:webView];
Swift版本：
if let docPath = NSBundle.mainBundle().pathForResource("sample", ofType: "pdf") { let docURL = NSURL(fileURLWithPath: docPath) webView.loadRequest(NSURLRequest(URL: docURL)) }
对MartinAlléus的回答进行更新，无论是手机还是iPad，无需硬编码即可获得全屏显示：
CGRect rect = [[UIScreen mainScreen] bounds]; CGSize screenSize = rect.size; UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,screenSize.width,screenSize.height)]; NSString *path = [[NSBundle mainBundle] pathForResource:@"pdf" ofType:@"pdf"]; NSURL *targetURL = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; [webView loadRequest:request]; [self.view addSubview:webView];
NSString *path = [[NSBundle mainBundle] pathForResource:@"document" ofType:@"pdf"]; NSURL *targetURL = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; [webView loadRequest:request];
UIWebView *pdfWebView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)]; NSURL *targetURL = [NSURL URLWithString:@"application/uploads/2014/12/pdf-sample.pdf"]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; [pdfWebView loadRequest:request]; [self.view addSubview:pdfWebView];
