Parse JSON Response with Afnetworking

Parse JSON file using AFNetworking

Change the second line in this:

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

to this:

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

Note you are using the AFJSONResponseSerializer response serialised.

Update

Updating my answer from info in the below comments, it appears you actually want to download a JSON file from a server and then parse it as opposed to parsing JSON directly from the HTTP response:

In order to do that change the content type to text/plain and with the downloaded file/data parse either as a String or a JSON object like this:

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:nil];
operation.responseSerializer = [AFHTTPResponseSerializer serializer];
operation.responseSerializer.acceptableContentTypes =
    [NSSet setWithObjects:@"application/octet-stream", @"text/plain", nil];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
  NSError *error;
  id json = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:&error];
  if (error) {
      NSLog(@"Error: %@", error);
  } else {
      NSLog(@"JSON: %@", json);
  }
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

  UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Weather"
                                                      message:[error localizedDescription]
                                                     delegate:nil
                                            cancelButtonTitle:@"Ok"
                                            otherButtonTitles:nil];
  [alertView show];
}];

AFNetworking and jSON

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"link"]];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request 
    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
        NSDictionary *jsonDict = (NSDictionary *) JSON;
        NSArray *products = [jsonDict objectForKey:@"products"];
        [products enumerateObjectsUsingBlock:^(id obj,NSUInteger idx, BOOL *stop){
            NSString *productIconUrl = [obj objectForKey:@"icon_url"];
        }];

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response,
        NSError *error, id JSON) {
            NSLog(@"Request Failure Because %@",[error userInfo]); 
    }
];

[operation start];

Try this.

Update 1: You can try this https://github.com/SSamanta/SSRestClient

Parsing JSON with AFNetworking

You have an array of dictionaries. To have an array of outputs you can use the following method:

- (NSMutableArray *)getValueString: (NSString*)string fromArray: (NSArray *)inputArray {
NSString *outputString;
NSMutableArray *outputArray = [NSMutableArray new];

for (id dict in inputArray) {
    if ([[dict class] isSubclassOfClass:[NSDictionary class]]) {
        outputString = [dict valueForKey: string];
    }
    else {
        outputString = @"Name not found";
    }

    if (!(outputString.length > 0)) {
        outputString = @"Name not found";
    }

    [outputArray addObject: outputString];
}

return outputArray;

}

And use it to get name with:

NSArray *resultArray = [self getValueString: @"name" fromArray: inputArray];
NSString *firstName = resultArray[0];

And to get id with:

NSArray *resultArray = [self getValueString: @"id" fromArray: inputArray];
NSString *firstId = resultArray[0];

Parse JSON from AFNetworking - Swift

you could do something like:

    let manager = AFHTTPRequestOperationManager()
manager.GET("http://api.androidhive.info/json/movies.json", parameters: nil, success: { (operation, responseObject) -> Void in
    let jsonArrays = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as? NSArray
        var arrayofDesiereValue : [String] = []
        for value  in jsonArrays {
            if let value = value as? NSDictionary {
                arrayofDesieredValue.append(value["desideredkey"] as! String)
            }
        }
    }, failure: nil)

How to parse a response obtained with AFNetworking 1.0 using JSON format

This solved my problem:

AFHTTPRequestOperation *requestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:jailbreakRequest];
[requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *requestOperation, id responseObject) {
    //Place this line of code below to create a NSDictionary from the async server response
    NSDictionary *jsonList = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
    } failure:^(AFHTTPRequestOperation *requestOperation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

[requestOperation start];

Thanks anyway :-)
