问题 I have been trying to download image/txt but i need to do it until that url exists & download that image/txt file,so i keep calling same method again & when i set debug point i see this . If url is right than i do not see any queue in debug navigator because it is not calling method again. i referred AFNetworking library to the same but i guess it`s working in same way as i am doing in NSURLSession,right? Case:- I check for url if exists or not, so if it`s exists than load both urls(time.txt

问题 Looking over the documentation of NSURLSession and NSURLSessionConfiguration , I was under the impression I should configure it with a dictionary like the following: // Create a dictionary to describe the proxy NSDictionary *proxyDict = @{ (NSString *)kCFProxyHostNameKey : @"myProxyHost.com", (NSString *)kCFProxyPortNumberKey : @"12345", (NSString *)kCFProxyTypeKey : (NSString*)kCFProxyTypeHTTP }; // Create a configuration that uses the dictionary NSURLSessionConfiguration *configuration =

问题 Authorization header is set in NSURLSessionConfiguration , however it is not attached to NSURLSessionDataTask . Is this a bug in Foundation framework ? NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; [configuration setHTTPAdditionalHeaders:@{@"Authorization":@"123"}]; // Initialize session with NSURLSessionConfiguration NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration]; NSMutableURLRequest *request = [

问题 I'm trying to upload large files using AFNetworking and have the upload continue when the application is in the background. I can upload files just fine, but when I attempt to use a background configuration -- the application crashes with the following stacktrace: Exception: EXC_BAD_ACCESS (code=1, address=0x8000001f)) _CFStreamSetDispatchQueue -[__NSCFBackgroundDataTask captureStream:] __70-[__NSCFBackgroundDataTask _onqueue_needNewBodyStream:withCompletion:]_block_invoke_2 _dispatch_call

问题 My app get a silent push, then do some http request in background using AFNetworking,but it didn't enter the complete block, code is: AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] init]; [manager GET:urlString parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) { NSLog(@"response objece:%@", responseObject); } failure:^(NSURLSessionDataTask *task, NSError *error) { NSLog(@"error:%@", error); }]; then I found maybe I could use NSURLSessionConfiguration to

问题 I want to subclass NSURLSession class, but I have problem with initialisation. Basically I override the constructor and initialising the constant authUrl there then calling the parent init method. class NSURLAuthSession: NSURLSession { let authUrl:NSURL; //Error: Initializer does not override a designated initializer from its superclass override init(configuration: NSURLSessionConfiguration, delegate: NSURLSessionDelegate?, delegateQueue queue: NSOperationQueue?){ self.authUrl = NSURL

问题 I know about the HTTPMaximumConnectionsPerHost option on NSURLSessionConfiguration ... but how many connections can iOS handle irrespective of host? I assume this depends on some combination of... the # of cores.. the network interface.. and how busy the OS is in general + with downloads for other applications. Can't find any hints about this. Regardless I assume it's ridiculous to expect more than 2 or 3 at once.. Edit Assuming the ability to have as many hosts and NSURLSession instances as

问题 I am using the following code to upload image using NSURLSessionUploadTask NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"]; NSURLRequest *request = [NSURLRequest requestWithURL:URL]; NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"]; NSURLSessionUploadTask
