推荐答案

如果您只是想查看PDF文件，您可以将其加载到UIWebView中。

If you simply want to view a PDF file you can load it into a UIWebView.

let url : NSURL! = NSURL(string: "http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIWebView_Class/UIWebView_Class.pdf")
webView.loadRequest(NSURLRequest(URL: url))

Swift 4.1：

let url: URL! = URL(string: "http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIWebView_Class/UIWebView_Class.pdf")
webView.loadRequest(URLRequest(url: url))
