nsurlsession

问题 I'm trying to create a transparent NSURLProtocol for http:// and https:// connections using NSURLSession. However at the moment, even though the completion handler is being run, URL requests with the app (UIWebView) are coming back blank. Does anybody have any ideas? Code is below: #import "MyURLProtocol.h" // AppDelegate #import "AppDelegate.h" static NSString * const MyURLProtocolHandledKey = @"MyURLProtocolHandledKey"; @interface MyURLProtocol () <NSURLConnectionDelegate

问题 I am in the process of upgrading one of my apps to iOS 7 and thought of trying out the new multitasking apis. I am planning to use Background Fetching or Silent push notifications to keep my content uptodate. Basically set of JSON values. Most of the documentation/code I looked through download videos or images and I have following questions... If we use Background Fetching or Silent push notifications, do we need to download data using a separate backgroundSessionConfiguration ? Or can we do

问题 So I am trying to get a simple string of data back from a RESTful API. Here is what a response looks like: Hello It is not formatted in XML or JSON or anything just a simple string because only one word is being passed back at a time. So here is what my swift looks like: let task = session.dataTaskWithURL(url!, completionHandler: { (data, response, error) -> Void in if error != nil { println("error: \(error.localizedDescription): \(error.userInfo)") } var withNewLine:NSString = NSString(data:

问题 I have requirement to download files in serial order. Currently I am able to do that while app is in foreground. Following is the logic I have used. Create all tasks for downloading. Resume one at a time and as the current finishes resume the next one from URLSession:task:didCompleteWithError: . This logic is working while app is in foreground but once app started to run in background(By crashing) and we again run the app before download finishes all the tasks state has been changed to resume

问题 I have created a very simple app to download a text file from my web server. I have this working perfectly with NSURLConnection, but am trying to migrate over to NSURLSession instead. The issue I am having is that none of the delegate methods are being called. My server is password protected so I need to use the basic http authentication to access the file, but when the didReceiveChallenge method is never called. The line of code [getFileTask resume] seems to have no effect on anything. My

问题 I created a tweak project using rpetrich's theos and wanted to hook NSURLSession methods but the hooks don't seem to get invoked? Why? This is my Tweak.xm code: %hook NSURLSession - (NSURLSessionDataTask *)dataTaskWithRequest:(NSURLRequest *)request completionHandler:(void (^)(NSData *data, NSURLResponse *response, NSError *error))completionHandler { NSLog(@"testhook dataTaskWithRequest:completionHandler:"); return %orig(request, completionHandler); } - (NSURLSessionDataTask *

问题 I am trying to upload a video / image file using - (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request fromFile:(NSURL *)fileURL; method using multi-part form data. But somehow i am not able to upload the file and i am getting " stream ended unexpectedly " error. Requirements Upload a video / image file to server App should support background uploads (Continue the upload process even after app goes into background) Server expects the data to be sent using multi-part form

问题 I've been traditionally using a pattern where NSOperation subclasses create and manage their own NSURLConnection. The NSOperation subclass is instantiated by the view controller and will do its work without bothering the controller until it has finished. When it finishes retrieving data, it executes the completion block supplied by the view controller. ViewController instantiates NSOperation subclass (which encapsulates URL, parameters etc) NSOperation subclass instanciates NSURLConnection
