how to cast response object to an object

[manager POST:urlString parameters:[self jsonDict] success:^(AFHTTPRequestOperation *operation, id responseObject){

        NSLog(@"response data: %@", responseObject);


        NSArray *postFromResponse = [ responseObject valueForKeyPath:@"credentials"];
    NSLog(@"credentials:%@", postFromResponse);

        for(NSDictionary *object in postFromResponse)
        {
            NSString *AccessKeyId = [object valueForKeyPath:@"AccessKeyId"];
            NSLog(@"%@", AccessKeyId);
        }



}

It gives me error:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFString 0x79ea4430> valueForUndefinedKey:]: this class is not key value coding-compliant for the key AccessKeyId'

Try this:

NSMutableDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
NSArray *postFromResponse = [responseDict valueforkey:@"credentials"];
for(NSDictionary *object in postFromResponse) {
  NSString *AccessKeyId = [object valueforkey:@"AccessKeyId"];
  NSLog(@"%@", AccessKeyId);
}
