nsurlconnection

问题 I stuck from last 2 days on this issue. please help me out. My requirement is, if I downloading a file in background in second view controller and after download starting I pop to 1st view controller and If I again push to 2nd view controller then that progress should be continue. Here what happening : I push to second view controller. I started Download using NSMutableURLRequest , NSURLConnection . If I pop to 1st view controller and again go to 2nd view controller then all are showing 0.

问题 In iOS 9, I'm using NSURL with NSURLConnection and for one specific URL, it's generating the following error in the - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error delegate method. Error Domain=NSPOSIXErrorDomain Code=89 "Operation canceled" UserInfo={NSErrorFailingURLStringKey=URL, _kCFStreamErrorDomainKey=1, NSErrorPeerAddressKey={length = 16, capacity = 16, bytes = 0x100201bb41d733370000000000000000}, _kCFStreamErrorCodeKey=89, NSErrorFailingURLKey=URL}

问题 Basically what's happening is that I need to download a whole bunch of files in my app and I've set up a queue of sorts that downloads each file with an NSURLConnection and stores the server response incrementally in an NSMutableData until the download is finished and then writes the whole thing to disk. Here's the relevant parts: - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)_response { response = [_response retain]; if([response expectedContentLength]

问题 I am having trouble caching NSURLConnection responses using a synchronous call. I initialize the cache in one class and then use it in another. Notice how the cache memory capacity gets initialized to 100KB but then is magically reset to zero later. - (id)init { if (self = [super init]) { // Creates a custom URL cache that uses both memory and disk. NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:kMemoryCacheSize * 1000000 diskCapacity:kDiskCacheSize * 1000000 diskPath

问题 Friends i have simple audio player (MPMoviePlayerController) which can play audio stream. On iOS 11 i have very interessing trouble, thousand time i have error and my stream was stopped: NSURLConnection finished with error - code -1002 I paste this code (this code i saw on stackowerflow) but it's not help to me: <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> <key>NSExceptionDomains</key> <dict> <key>cast.mysite.com</key> <dict> <key

问题 Whenever I attempt to post something to my PHP Server, I receive the following message. It seems as if the code is connecting to the server, but no data is returned, and the post data isn't going through. It worked through a Java App that I made, so I can assure that their is nothing wrong with my PHP. If you could help me, or need any more code to help me, just ask for it. Thanks. Here is the code that prepares my variables for the NSURLConnection: NSString *phash = [NSString

问题 I've seen this error around before and it seems the remedy is to add info to the .plist file. I've tried each of the ones I've seen: How do I load an HTTP URL with App Transport Security enabled in iOS 9? NSURLSession/NSURLConnection HTTP load failed on iOS 9 NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802) on a subdomain? Still my program results in the same error thrown: 2017-05-08 08:29:37.781075-0400 xxxx[3256:408961] [] nw_coretls_callback_handshake_message

问题 I have to make json post request with the following request parameters, { "method":"login", "data":{ "username":"korea", "password":"123456" } } I use the following code to make the request, NSString *jsonRequest = [NSString stringWithFormat:@"{""\"\method:\"\login\"\"\,""\data:\"{\"\"username\":\"%@\",\"password\":\"%@\"}",username,password]; NSLog(@"Request: %@", jsonRequest); NSURL *url = [NSURL URLWithString:@"http://myurl..."]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc]

问题 I would like to launch a request with NSMutableURLRequest when the answer of the [NSURLConnection sendAsynchronousRequest: get a good status code. When I launch the executeForStatusOkMetod containing the NSMutableURLRequest alone, it works perfectly. But if I launch the executeForStatusOkMetod with the [NSURLConnection sendAsynchronousRequest: , the connectionDidFinishLoading: function is never called. Here is the main code : NSOperationQueue *myQueue = [[NSOperationQueue alloc] init];

问题 I am working with an app which is todo list organizer, where user adds notes. I am using coredata DB to store the notes. As I am providing sync feature, I am parsing JSON data to server, and also getting JSON data from server. I am using NSURLConnection API and its delegate functions - (void)pushData { loop through the notes array and send notes 1 by one [[request setValue:@"application/json;charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [request setHTTPMethod:@"POST"]; [request
