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
They are invoked on the main queue, unless you explictly sets the queue on AFHTTPRequestOperation, as shown in setCompletionBlockWithSuccess:failure from AFHTTPRequestOperation.m self.completionBlock = ^{ if (self.error) { if (failure) { dispatch_async(self.failureCallbackQueue ?: dispatch_get_main_queue(), ^{ failure(self, self.error); }); } } else { if (success) { dispatch_async(self.successCallbackQueue ?: dispatch_get_main_queue(), ^{ success(self, self.responseData); }); } } };
Thanks Sendoa for the link to the GitHub issue where Mattt explains why this functionality is not working anymore. There is a clear reason why this isn’t possible with the new NSURLSession structure; Tasks just aren’t operations, so the old way of using dependencies or batches of operations won’t work. I’ve created this solution using … Read more
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];
AFNetworking and Alamofire are by the same people (the Alamofire Software Foundation), Alamofire is their Swift version whereas AFNetworking is the Objective-C version. Feature wise they are the same.
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
Yes, your session ID should be sent automatically once you are logged in, as long as the cookie does not expire before the next request is sent (important detail to be sure of). NSURLConnection, which AFNetworking uses, takes care of the details for this for you. On the backend AFNetworking is using NSURLConnection which in … Read more
Here is the method I use to get the content of a directory. -(NSArray *)listFileAtPath:(NSString *)path { //—–> LIST ALL FILES <—–// NSLog(@”LISTING ALL FILES FOUND”); int count; NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:NULL]; for (count = 0; count < (int)[directoryContent count]; count++) { NSLog(@”File %d: %@”, (count + 1), [directoryContent objectAtIndex:count]); } return … Read more
According to the official documentation, modifying the session configuration is not recommended: This is not recommended for Authorization or Content-Type headers. Instead, use URLRequestConvertible and ParameterEncoding, respectively. So an example usage of URLRequestConvertible for authorization would be: enum Router: URLRequestConvertible { static let baseUrlString = “some url string” case Get(query: String) var URLRequest: NSMutableURLRequest { … Read more
Here’s an example using AFNetworking 2.0 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@”calvinAndHobbesRock” forHTTPHeaderField:@”X-I do what I want”]; [manager GET:@”http://localhost:3000″ parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@”JSON: %@”, responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@”Error: %@”, error); }]; The key are the following 2 lines: manager.requestSerializer … Read more
