[uzman]

hi,
please do below.

-download the AFNetwroking latest version.
-put the AFNetwrking dir to your project
-add the necessary framework to your project

• in OWMWeatherAPI.m class:
  add;
  //#import "AFJSONRequestOperation.h" --> delete this
  #import "AFHTTPRequestOperation.h"

here is the updated method:

• (void) callMethod:(NSString ) method withCallback:( void (^)( NSError error, NSDictionary *result ) )callback
  {

  NSOperationQueue *callerQueue = [NSOperationQueue currentQueue];

  // build the lang paramter
  NSString *langString;
  if (_lang && _lang.length > 0) {
  langString = [NSString stringWithFormat:@"&lang=%@", _lang];
  } else {
  langString = @"";
  }

  NSString *urlString = [NSString stringWithFormat:@"%@%@%@&APPID=%@%@", _baseURL, _apiVersion, method, _apiKey, langString];

  NSURL *url = [NSURL URLWithString:urlString];

  NSURLRequest *request = [NSURLRequest requestWithURL:url];

  /*
  AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {

  // callback on the caller queue
  NSDictionary *res = [self convertResult:JSON];
  [callerQueue addOperationWithBlock:^{
      callback(nil, res);
  }];
  

  } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {

  // callback on the caller queue
  [callerQueue addOperationWithBlock:^{
      callback(error, nil);
  }];
  

  }];
  [_weatherQueue addOperation:operation];
  */

  AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
  operation.responseSerializer = [AFJSONResponseSerializer serializer];
  [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

  // callback on the caller queue
  NSDictionary *res = [self convertResult:responseObject];
  [callerQueue addOperationWithBlock:^{
      callback(nil, res);
  }];
  

  } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
  //NSLog(@"error: %@", operation.responseString);
  [callerQueue addOperationWithBlock:^{
  callback(error, nil);
  }];

  }];
  [_weatherQueue addOperation:operation];

}
