nsurlconnection

问题 I'm currently experimenting with the twitter streaming api and i'm trying to get a stream with NSURLConnection . As it doesn't work with twitter, i simplified everything and tried to get some source-code out of google's website, but this doesn't work neither. The connection starts and ends, but without calling the didReceiveData delegate. I'm sure i'm missing something. Hope you guy's can help me! In the header: @interface ViewController : UIViewController <NSURLConnectionDataDelegate,

问题 Apparently, NSURLConnection automatically decodes gzipped responses. But, can it gzip encode its requests? If so, how? Or, does it do this automatically too? 回答1: An HTTP request body cannot be gzipped at the protocol level, as there is no way for the client to know whether the server supports that or not; it works for the server response because the client indicates in the request whether a gzipped response body can be accepted. (It could be done in the future something like how Expect: 100

问题 hello I used this below code to send a request to Server. How can I add the timeout in this function static func postToServer(url:String,var params:Dictionary<String,NSObject>, completionHandler: (NSDictionary?, String?) -> Void ) -> NSURLSessionTask { let request = NSMutableURLRequest(URL: NSURL(string: url)!) let session = NSURLSession.sharedSession() request.HTTPMethod = "POST" if(params["data"] != "get"){ do { let data = try NSJSONSerialization.dataWithJSONObject(params, options:

问题 I can't receive a notification with this: a class for doing NSURLConnection async stuff - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:_receivedData, @"receivedData", nil]; [[NSNotificationCenter defaultCenter] postNotificationName:kWebServiceURLTemperaturaMaximaKMLNotitificationName object:self userInfo:userInfo]; } another class observing the notification: [[NSNotificationCenter defaultCenter]

问题 Hi Im a newbie and Im trying to download geocoding data from googleapi webpage. I did it using this: code: NSMutableString *urlStr = [[NSMutableString alloc] initWithString:temp]; NSMutableString *address = [[NSMutableString alloc] initWithString:l.Address]; [address appendString:@" "]; [address appendString:l.CityName]; [address appendString:@" "]; [address appendString:l.State]; [address appendString:@" "]; [address appendString:l.PostalCode]; NSArray *addressArray = [address

问题 I am using this code... Reachability *r = [Reachability reachabilityWithHostName:@"www.maxqdata.com"]; NetworkStatus internetStatus = [r currentReachabilityStatus]; if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"You require an internet connection via WiFi or cellular network for location finding to work." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil

问题 Im making an app where one of the features I want to offers is to measure de download speed of the connection. To get this I`m using NSURLConnection to start the download of a large file, and after some time cancel the download and make the calculation (Data downloaded / time elapsed). While other apps like speedtest.net give a constant speed every time, mine fluctuates 2-3 Mbps more or less. Basically what I`m doing is, start the timer when the method connection:didReceiveResponse: is called

问题 I am having a problem with a network request that should timeout, but the method is not called. The request is as follows: #define kCONNECT_TIMEOUT 20.0 request = [NSMutableURLRequest requestWithURL: aUrl]; [request setHTTPMethod: @"POST"]; postData = [jsonData dataUsingEncoding:NSASCIIStringEncoding]; [request setHTTPBody:postData]; [request setValue:@"text/xml" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setCachePolicy

问题 I'm getting (kCFStreamErrorDomainSSL, -9813) when connecting to a client's server. The client's server has a self signed certificate that I can not change. The app is using AFNetworking 3.x. I've tried the following but nothing seems to work. If someone could help me, it will be much appreciated.
