How to get response from server using AFNetworking (Obj-C)?

Question

Objective-C

I decided to deal with AFNetworking and created a simple console application that contains only one POST request of this kind:

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager POST:@"http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"Error: %@", error);
}];

After starting the project, NSLog does not output anything to the console. Help me figure out what the problem is.

The problem is that when return 0; is called; in the main function, the application terminates. And since in afnetworking the request is asynchronous, it simply does not have time to work.
Make an application with one controller / window and paste the code there
