通过API下载PDF时遇到问题。问题如下:
我可以通过API链接下载PDF。下载完成。但它的路径是/ Users / *********** / Library / Developer / CoreSimulator / Devices / 58BD307-ED3A-4F34-9FCB-3391FDCC068D / data / Containers / Data / Application / DBB11FA91-2387- 4124-9E07-2E92B22636B5 /文档/ tfData。 如何更改路径?
我需要将下载的PDF存储在核心数据中,我需要在核心数据的Web视图中显示。我不能这样做。请指导我。
2.1首先,我不知道如何将下载的PDF显示到我的网页视图中。
我的编码部分:
//FATAL ERROR RECEIVING
let filemanager = NSFileManager.defaultManager()
let documentsPath : AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory,.UserDomainMask,true)[0]
let destinationPath:NSString = documentsPath.stringByAppendingString("/tfData.pdf")
println("destinationPath \(destinationPath)")
let pdf = NSURL(fileURLWithPath: destinationPath as String)
println("destinationPath pdf \(pdf)")
let req = NSURLRequest(URL: pdf!)
println("destinationPath req \(req)")
let webView = UIWebView(frame: CGRectMake(20,20,self.view.frame.size.width-40,self.view.frame.size.height-40))
webView.loadRequest(req)
self.view.addSubview(webView)
//NOT DISPLAYING IN WEB VIEW.
日志
destinationPath /Users/***********/Library/Developer/CoreSimulator/Devices/58BD307-ED3A-4F34-9FCB-3391FDCC068D/data/Containers/Data/Application/DBB11FA91-2387-4124-9E07-2E92B22636B5/Documents/tfData.pdf
destinationPath pdf Optional(file:///Users/***********/Library/Developer/CoreSimulator/Devices/58BD307-ED3A-4F34-9FCB-3391FDCC068D/data/Containers/Data/Application/DBB11FA91-2387-4124-9E07-2E92B22636B5/Documents/tfData.pdf)
destinationPath req <NSURLRequest: 0x7f8083706330> { URL: file:///Users/***********/Library/Developer/CoreSimulator/Devices/58BD307-ED3A-4F34-9FCB-3391FDCC068D/data/Containers/Data/Application/DBB11FA91-2387-4124-9E07-2E92B22636B5/Documents/tfData.pdf }
请指导我。如何解决这个问题?我只能做第一件事。
为什么我这样做意味着,用户也可以在离线模式下阅读pdf。所以我需要这样的。
答案 0 :(得分:1)
您可以在webView中以这种方式加载PDF:
if let pdf = NSBundle.mainBundle().URLForResource("yourPDFName", withExtension: "pdf", subdirectory: nil, localization: nil) {
let req = NSURLRequest(URL: pdf)
let webView = UIWebView(frame: CGRectMake(20,20,self.view.frame.size.width-40,self.view.frame.size.height-40))
webView.loadRequest(req)
self.view.addSubview(webView)
}
