NSURLConnection 在更新到 Swift 2.0 后抛出

本文介绍了NSURLConnection 在更新到 Swift 2.0 后抛出的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在 Swift 2.0 更新之前，此代码非常适合使用 PHP 脚本从服务器下载我的 JSON 文件:

Before the Swift 2.0 Update this code worked perfectly to download my JSON File from the Server with a PHP Script:

let url = NSURL(string: webAdress) let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 5.0) var response: NSURLResponse? = nil var error: NSError? = nil let reply = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&error)

更新后 Xcode 要求我做一些更改.我做了，代码没有错误，但它总是抛出...

After the Update Xcode asked me to do some changes. I did and the code had no Error, but it always throws...

let url = NSURL(string: webAdress) let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData let request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 5.0) var response: NSURLResponse? = nil var reply = NSData() do { reply = try NSURLConnection.sendSynchronousRequest(request, returningResponse:&response) } catch { print("ERROR") }

期待您的解决方案！

推荐答案

这是一个使用新 NSURLSession 的示例 - 显然 NSURLConnection 在 iOS 9 中已被弃用.

Here's an example using the new NSURLSession - apparently NSURLConnection has been deprecated in iOS 9.

let url = NSURL(string: webAddress) let request = NSURLRequest(URL: url!, cachePolicy: .ReloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 5.0) let session = NSURLSession.sharedSession() session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in print(data) print(response) print(error) })?.resume()

我认为它非常干净，只是没有太多关于它的文档.如果您在使用它时遇到任何问题，请告诉我.

I think it's super clean, there's just not much documentation on it. Let me know if you have any trouble getting this to work.
