Answer 1

Well it was pretty simple. All was missing is conversion of imagedata into base64EncodedString. Here is the solution.

   NSString *media = @"https://upload.twitter.com/1.1/media/upload.json";

   NSData *imageData = UIImageJPEGRepresentation(image, 0.9);

   NSString *imageString = [imageData base64EncodedStringWithOptions:0];
   NSError *error;
   NSURLRequest *request = [[[Twitter sharedInstance] APIClient] URLRequestWithMethod:@"POST" URL:media parameters:@{@"media":imageString} error:&error];

   [[[Twitter sharedInstance] APIClient] sendTwitterRequest:request completion:^(NSURLResponse *urlResponse, NSData *data, NSError *connectionError) {

       NSError *jsonError;
       NSDictionary *json = [NSJSONSerialization
                              JSONObjectWithData:data
                              options:0
                              error:&jsonError];
       NSLog(@"Media ID :  %@",[json objectForKey:@"media_id_string"]);

      // Post tweet With media_id
    }];
