copied!<p><em>Answer updated for AFNetworking 2.x</em></p> <h2>For AFNetworking 2.x:</h2> <p>In 2.x, they did away with AFHTTPClient, so you'll need to extend AFHTTPRequestOperationManager with your own class. Then, you can call that class from other code. For example, here's a sample class that extends the AFHTTPRequestOperationManager:</p> <p>SBAPIManager.h:</p> <pre><code>#import "AFHTTPRequestOperationManager.h" @interface SBAPIManager : AFHTTPRequestOperationManager - (void)setUsername:(NSString *)username andPassword:(NSString *)password; + (SBAPIManager *)sharedManager; @end </code></pre> <p>SBAPIManager.m:</p> <pre><code>#import "SBAPIManager.h" #import "AFNetworkActivityIndicatorManager.h" @implementation SBAPIManager #pragma mark - Methods - (void)setUsername:(NSString *)username andPassword:(NSString *)password { [self.requestSerializer clearAuthorizationHeader]; [self.requestSerializer setAuthorizationHeaderFieldWithUsername:username password:password]; } #pragma mark - Initialization - (id)initWithBaseURL:(NSURL *)url { self = [super initWithBaseURL:url]; if(!self) return nil; self.requestSerializer = [AFJSONRequestSerializer serializer]; [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES]; return self; } #pragma mark - Singleton Methods + (SBAPIManager *)sharedManager { static dispatch_once_t pred; static SBAPIManager *_sharedManager = nil; dispatch_once(&pred, ^{ _sharedManager = [[self alloc] initWithBaseURL:[NSURL URLWithString:@"http://localhost:3000"]]; }); // You should probably make this a constant somewhere return _sharedManager; } @end </code></pre> <p>Then, in your code, you can call it like this:</p> <pre><code>[[SBAPIManager sharedManager] setUsername:yourUsernameVariableHere andPassword:yourPasswordVariableHere]; [[SBAPIManager sharedManager] GET:@"/tasks.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { self.tasks = [responseObject objectForKey:@"results"]; [self.activityIndicatorView stopAnimating]; [self.tableView setHidden:NO]; [self.tableView reloadData]; NSLog(@"JSON"); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { // error stuff here }]; </code></pre> <hr> <h2>For AFNetworking 1.x:</h2> <p>The best practice for this in AFNetworking is to extend the AFHTTPClient with your own class. Then, you can call that class from other code. For example, here's a sample class that extends the AFHTTPClient:</p> <p>SBAPIManager.h:</p> <pre><code>#import "AFNetworking/AFHTTPClient.h" @interface SBAPIManager : AFHTTPClient - (void)setUsername:(NSString *)username andPassword:(NSString *)password; + (SBAPIManager *)sharedManager; @end </code></pre> <p>SBAPIManager.m:</p> <pre><code>#import "SBAPIManager.h" #import "AFJSONRequestOperation.h" #import "AFNetworkActivityIndicatorManager.h" @implementation SBAPIManager #pragma mark - Methods - (void)setUsername:(NSString *)username andPassword:(NSString *)password { [self clearAuthorizationHeader]; [self setAuthorizationHeaderWithUsername:username password:password]; } #pragma mark - Initialization - (id)initWithBaseURL:(NSURL *)url { self = [super initWithBaseURL:url]; if(!self) return nil; [self registerHTTPOperationClass:[AFJSONRequestOperation class]]; [self setDefaultHeader:@"Accept" value:@"application/json"]; [self setParameterEncoding:AFJSONParameterEncoding]; [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES]; return self; } #pragma mark - Singleton Methods + (SBAPIManager *)sharedManager { static dispatch_once_t pred; static SBAPIManager *_sharedManager = nil; dispatch_once(&pred, ^{ _sharedManager = [[self alloc] initWithBaseURL:[NSURL URLWithString:@"http://localhost:3000"]]; }); // You should probably make this a constant somewhere return _sharedManager; } @end </code></pre> <p>Then, in your code, you can call it like this:</p> <pre><code>[[SBAPIManager sharedManager] setUsername:yourUsernameVariableHere andPassword:yourPasswordVariableHere]; [[SBAPIManager sharedManager] getPath:@"/tasks.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { self.tasks = [responseObject objectForKey:@"results"]; [self.activityIndicatorView stopAnimating]; [self.tableView setHidden:NO]; [self.tableView reloadData]; NSLog(@"JSON"); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { // error stuff here }]; </code></pre>
