问题 I am trying to pull some data from my local node server. The server is getting the get request and logging it, but for some reason my iOS app will not execute any of the code that I have in the completion handler. Here is the code: - (IBAction) buttonPressed{ NSURL *url = [NSURL URLWithString:@"http://127.0.0.1:3000/"]; NSURLSessionDataTask *dataTask = [self.session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error){ nameLabel.text = @"yay!"; /* if

问题 When I force my device to go in sleep mode by pressing the power button, my background task stops by calling the delegate method didCompleteWithError with the error : The operation couldn’t be completed. Operation not permitted How can I configure my NSURLSession to continue the download even in sleep mode? Is it even possible? If not, what options do I have? I need to download a file of 300Mb, so with a low connection the application will go in sleep mode before the end of the download. Here

问题 I have developed an IOS App that is communicating with a Server using HTTPs (I'm also the developer of the server, it's embedding a Tomcat server). This App is working without any issues with IOS8 but it's not with IOS9.
