推荐答案

是的，这可以通过UIWebView完成。

Yes, this can be done with the UIWebView.

如果您试图在某个地方显示驻留在服务器上的PDF文件，您可以直接在网页视图中加载它：

If you are trying to display a PDF file residing on a server somewhere, you can simply load it in your web view directly:

Objective-C

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];

Swift

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（在此示例中名为document.pdf）：

Or if you have a PDF file bundled with your application (in this example named "document.pdf"):

Objective-C

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];

Swift

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)
