How to download a file and save it to the documents directory with AFNetworking?

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@”…”]]; AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc] initWithRequest:request] autorelease]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@”filename”]; operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@”Successfully downloaded file to %@”, path); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@”Error: %@”, error); }]; [operation start];

iOS Image upload via AFNetworking 2.0

I ended up using the multi-part request UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage]; NSData *imageData = UIImageJPEGRepresentation(image, 0.5); AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSDictionary *parameters = @{@”foo”: @”bar”}; [manager POST:@”http://example.com/resources.json” parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFormData:imageData name:@”image”]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@”Success: %@”, responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@”Error: %@”, error); }];

Does AFNetworking have backgrounding support?

EDIT: As of AFNetworking 1.0RC1, this is an explicit feature. AFURLConnectionOperation now has the method setShouldExecuteAsBackgroundTaskWithExpirationHandler:, which transparently manages all of this for you. It’s an implicit feature, so I didn’t really think about advertising it. All you’d need to do is: – (void)applicationWillResignActive:(UIApplication *)application { __block UIBackgroundTaskIdentifier backgroundTaskIdentifier = [application beginBackgroundTaskWithExpirationHandler:^(void) { [application endBackgroundTask:backgroundTaskIdentifier]; … Read more

kCFStreamErrorDomainSSL, -9802 when connecting to a server by IP address through HTTPS in iOS 9

iOS9 requires the server to only support TLSv1.2 and support perfect forward security. Also required is for the app to support IPV6 including not using hard-coded IP addresses. Suggested is to use NSURLSession. Otherwise exception additions must be made in the app plist. See the WWDC-15 session “Security and your Apps”. Also see Steven Peterson’s … Read more

afnetworking 3.0 Migration: how to POST with headers and HTTP Body

Another way to call a POST method with AFNetworking 3.0 is: AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@”application/json” forHTTPHeaderField:@”Content-Type”]; [manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { NSLog(@”success!”); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@”error: %@”, error); }]; Hope it helps!

AFNetworking and background transfers

A couple of thoughts: You have to make sure you do the necessary coding outlined in the Handling iOS Background Activity section of the URL Loading System Programming Guide says: If you are using NSURLSession in iOS, your app is automatically relaunched when a download completes. Your app’s application:handleEventsForBackgroundURLSession:completionHandler: app delegate method is responsible for … Read more

Can AFNetworking return data synchronously (inside a block)?

To block the execution of the main thread until the operation completes, you could do [operation waitUntilFinished] after it’s added to the operation queue. In this case, you wouldn’t need the return in the block; setting the __block variable would be enough. That said, I’d strongly discourage forcing asynchronous operations to synchronous methods. It’s tricky … Read more
