It's led to my code being really untidy, especially I have request within request within request. I wanted to try using delegates in NSURLSession to implement something I've done untidily with NSURLConnection . So I created a NSURLSession , and created a dataTask : NSURLSessionDataTask *dataTask = [overallSession dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { if(error == nil) { NSString * text = [[NSString

The actual calling method that gives the error seems to vary but always comes from CFNetwork . For the most part, the calling method comes from NSURLSession delegate_dataTask:didReceiveData:completionHandler . I've attached two crash logs with different callers below. I've also attached my implementation of NSURLSessionDataDelegate . Unfortunately I cannot reliably reproduce the error, so I don't have an example script

In latest apple introduce new NSURLSession in replace of NSURLConnection , so in there are different task , so what is the difference between NSURLSessionDataTask , NSURLSessionDownloadTask ? and in which scenario use NSURLSessionTask and where NSURLSessionDownloadTask ? NSURLSessionDataTask : Data tasks exchange data using NSData. NSURLSessionDataTask is not supported in Background Sessions. Data tasks send and receive data using NSData objects. Data tasks are intended for short, often interactive requests from your app to a server. Data tasks can return data to your app one piece at a time

Everything was great with NSURLConnection, until I discovered it was outdated, and tried to work with NSURLSession. I am trying a very simple example, but can't seem to get my app to run the code inside the completion block. Here is the code used: NSURL * url = [NSURL URLWithString:@"http://api.openweathermap.org/data/2.5/weather?q=London,uk"]; NSLog(@"2"); NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration]; NSLog(

The app compiles ok, but when I attempt to call the category methods I get -[__NSCFURLSession doSomething]: unrecognized selector sent to instance 0xbf6b0f0 :0: error: -[NSURLSession_UPnPTests testCategory] : -[__NSCFURLSession doSomething]: unrecognized selector sent to instance 0xbf6b0f0 Very strange, here is a test class I built to show the issue. The category on the NSString works fine, but the category on NSURLSession fails to find the method at runtime. I suspect this is something internal

Seems like uploadTaskWithRequest:fromData: doesn't work with NSURLSession created with backgroundSessionConfiguration since it causes an exception: "Terminating app due to uncaught exception 'NSGenericException', reason: 'Upload tasks in background sessions must be from a file". Judging from the exception description background transfer shouldn't work with streamed upload tasks too. Fair enough. uploadTaskWithRequest:fromFile: is the first thing that comes to

I want to download a List of files using NSUrlSession. I have a variable for counting the successful downloads @property (nonatomic) int downloadsSuccessfulCounter; . While the files are being downloaded I disable the Download Button . When the counter is equal to the download list size, I enable the button again and set the counter to 0. I do this in the method: -(void)URLSession:(NSURLSession *)session downloadTask:(NSURLSessionDownloadTask *)downloadTask didFinishDownloadingToURL:(NSURL *)location { ... [[NSOperationQueue mainQueue] addOperationWithBlock:^ { downloadsSuccessfulCounter++; if

I'm trying to learn about working with APIs in Swift. As a good first test, I figured I'd hit the itunes API and just return some search results. I'm in playground using the following code. I don't get any errors, but my println isn't outputting anything. Anyone know what's wrong? Thanks! import UIKit import XCPlayground XCPSetExecutionShouldContinueIndefinitely() let url = NSURL(string: "https://itunes.apple.com/lookup?id=909253") let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in println(NSString(data: data, encoding: NSUTF8StringEncoding)) } task

I have implemented NSURLSession for downloading fairly large files from our servers. Now as long as I'm working in foreground or background and go back to the app the transactions are working and getting finished. But if I force-quit the app using the the multitasking screen and re-open the app again. the downloading process is not getting finished although as I understood from the docs, it should, here what the docs state: If an iOS app is terminated by the system and relaunched, the app can use the same identifier to create a new configuration object and session and retrieve the status of
