AFNetworking: Create POST request, but not run

Question

I'm trying to create POST request in AFNetworking 2.0:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

AFHTTPRequestOperation *operation = [manager POST: requestURL parameters:params 
 success:^(AFHTTPRequestOperation *operation, id responseObject) {

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

}];

But how I can create AFHTTPRequestOperation without executing it immediately? ( I need to add this operation to NSOperationQueue )

UPDATE:

Thanks! I ended up with such solution:

 NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod: @"POST" URLString: @"website" parameters: params error: nil];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

}];

[operation start]; // or add operation to queue

Answer 1

Straight from the docs

NSURL *URL = [NSURL URLWithString:@"http://example.com/foo.json"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

operation.responseSerializer = [AFJSONResponseSerializer serializer];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"%@", responseObject);
    } failure:nil];

[operation start];

Edit

If you want to submit this operation to NSOperationQueue, you can use AFHTTPRequestOperationManager as follows

requestManager = [AFHTTPRequestOperationManager manager];

// instead of [operation start]
[requestManager.operationQueue addOperation:operation];

The best way to add something to an NSOperationQueue is to subclass NSOperation.

There are tutorials all over the place... First example I found with a Google search.

You subclass might be called MyPostOperation.

And it has the single task of running your POST request.

It then gets managed and run by your NSOperationQueue.

Try this

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer] 

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"%@", responseObject);
} failure:nil];
// Add the operation to a queue
// It will start once added
NSOperationQueue *operationQueue = [[NSOperationQueue alloc] init];
[operationQueue addOperation:operation];
