Get Responseobject on Failure Block Afnetworking 3.0

get responseObject on failure block AFNetworking 3.0

Just do this in your failure block:-

 NSString* errResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(@"%@",errResponse);

For Swift:-

var errResponse: String = String(data: (error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] as! NSData), encoding: NSUTF8StringEncoding)
NSLog("%@", errResponse)

Updated for Swift 4.1

var errResponse: String = String(data: (error._userInfo![AFNetworkingOperationFailingURLResponseDataErrorKey] as! Data), encoding: String.Encoding.utf8)!
print(errResponse)

AFNetworking: how to get the response string when failed?

You may log operation.responseString line in success and failure block both to get response string of server.

If webservice has some kind of error and provide invalid json or response then log [error description] in failure block.

For reference please check below code snippet.

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setTimeoutInterval:120];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
[manager POST:[[NSString stringWithFormat:@"%@",URL]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] parameters:parameters 
     success:^(AFHTTPRequestOperation *operation, id responseObject) 
     {
       NSLog(@"Response: %@", operation.responseString);  
     } 
     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
     {
       NSLog(@"Error: %@ \n %@", operation.responseString,[error description]);
     }];

AFNetworking 3.0 GET request save into class in iOS

Add all events to an array, you will then have an array of dictionaries. Also make a new array which will hold your new instances.
Now:

for (NSDictionary *dictionary in myArrayContainingAllEvents){
    GeeksLocation *location = [GeeksLocation alloc] initWithDictionary:dictionary]; 
    [newArrayForInstances addObject: location];
}

In the GeeksLocation class add the following initializer:

-(instanceType)initWithDictionary: (NSDictionary *) dictionary{ 
     self = [super init];
     if(self){
            self.geeksAddress = [dictionary objectForKey:address];
            self.....         = [dictionary objectForKey:.......];
     }

     return self;
}

Hope this helps
