AFNetworking is Deprecated

As of Jan. 17, 2023, AFNetworking is deprecated and there will be no further releases. This repo will remain online in perpetuity as an archive. There are a couple options for continued AFNetworking use:

Copy AFNetworking into your project and compile it directly. This gives you full control over the code.
Fork AFNetworking and use the fork in your dependency manager. There will be no official forks but anyone can fork at any time and can even publish those forks under a different name, in accordance with AFNetworking's license.

Moving forward, Alamofire is the suggested migration path for networking in modern Swift. Anyone who needs help making that migration is welcome to ask on StackOverflow and tag alamofire and afnetworking, or open a discussion on Alamofire's GitHub Discussions regarding any migration issues or missing features.

AFNetworking is a delightful networking library for iOS, macOS, watchOS, and tvOS. It's built on top of the Foundation URL Loading System, extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.

Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.

Installation

AFNetworking supports multiple methods for installing the library in a project.

Installation with CocoaPods

To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'AFNetworking', '~> 4.0'

Installation with Swift Package Manager

Once you have your Swift package set up, adding AFNetworking as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/AFNetworking/AFNetworking.git", .upToNextMajor(from: "4.0.0"))
]

Note: AFNetworking's Swift package does not include it's UIKit extensions.

Installation with Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate AFNetworking, add the following to your Cartfile.

github "AFNetworking/AFNetworking" ~> 4.0

Usage

AFURLSessionManager

AFURLSessionManager creates and manages an NSURLSession object based on a specified NSURLSessionConfiguration object, which conforms to <NSURLSessionTaskDelegate>, <NSURLSessionDataDelegate>, <NSURLSessionDownloadDelegate>, and <NSURLSessionDelegate>.

Creating a Download Task

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
    NSLog(@"File downloaded to: %@", filePath);
}];
[downloadTask resume];

Creating an Upload Task

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 *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"Success: %@ %@", response, responseObject);
    }
}];
[uploadTask resume];

Creating an Upload Task for a Multi-Part Request, with Progress

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
    } error:nil];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
              uploadTaskWithStreamedRequest:request
              progress:^(NSProgress * _Nonnull uploadProgress) {
                  // This is not called back on the main queue.
                  // You are responsible for dispatching to the main queue for UI updates
                  dispatch_async(dispatch_get_main_queue(), ^{
                      //Update the progress view
                      [progressView setProgress:uploadProgress.fractionCompleted];
                  });
              }
              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                  if (error) {
                      NSLog(@"Error: %@", error);
                  } else {
                      NSLog(@"%@ %@", response, responseObject);
                  }
              }];

[uploadTask resume];

Creating a Data Task

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"%@ %@", response, responseObject);
    }
}];
[dataTask resume];

Request Serialization

Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body.

NSString *URLString = @"http://example.com";
NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};

Query String Parameter Encoding

[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];

GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3

URL Form Parameter Encoding

[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];

POST http://example.com/
Content-Type: application/x-www-form-urlencoded

foo=bar&baz[]=1&baz[]=2&baz[]=3

JSON Parameter Encoding

[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];

POST http://example.com/
Content-Type: application/json

{"foo": "bar", "baz": [1,2,3]}

Network Reachability Manager

AFNetworkReachabilityManager monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.

Do not use Reachability to determine if the original request should be sent.
- You should try to send it.
You can use Reachability to determine when a request should be automatically retried.
- Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something.
Network reachability is a useful tool for determining why a request might have failed.
- After a network request has failed, telling the user they're offline is better than giving them a more technical but accurate error, such as "request timed out."

See also WWDC 2012 session 706, "Networking Best Practices.".

Shared Network Reachability

[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
}];

[[AFNetworkReachabilityManager sharedManager] startMonitoring];

Security Policy

AFSecurityPolicy evaluates server trust against pinned X.509 certificates and public keys over secure connections.

Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an HTTPS connection with SSL pinning configured and enabled.

Allowing Invalid SSL Certificates

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production

Unit Tests

AFNetworking includes a suite of unit tests within the Tests subdirectory. These tests can be run simply be executed the test action on the platform framework you would like to test.
