Basic authentication using AFNetworking

As well as other publications found here, the request is very similar. You will only need to add% of the authentication data using the requestSerializer method.

In general, it looks something like this:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.requestSerializer = [AFHTTPRequestSerializer serializer];

[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"usuario" password:@"senha"];

[manager GET:@"http://..." parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *response = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", response);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
