How to perform AFHTTPRequestOperation in AFNetworking 2

Question

I've implemented the JSON parsing using AFNetworking 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 AFNetworking again and I installed in using pods 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 or 3 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 AFNetworking.

Answer 1

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 !
