How to perform AFHTTPRequestOperation in AFNetworking 2

I've implemented the JSON parsing using

many time in some previous apps as:

NSString *string = [NSString stringWithFormat:@"%@?get_all_data", BaseURLString];
NSURL *url = [NSURL URLWithString:string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
//performing parsing here

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//error message displayed here

But as of today I started working on an app after a while I came to use
again and I installed in using
so as I write this same code as I use to write before it gives me the error saying
Unknown Receiver AFHTTPRequestOperation. Do you mean AFHTTPRequestSerializer?

After searching about it I found that it's
AFNetworking 2
era now and they have somehow changed the scenerio. I didn't find the exact solution on how to implement it now. So can anyone write the code in the answer below that works with the latest version of


This is the new approach of AFNetworking 3.x to parse data:

NSString *path = @"yourapilink";
NSString *escapedPath = [path stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

[manager GET:escapedPath  parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);

Hope it help !
