How to post image with private tweet using SLRequest in iOS? - ios

Question

I have a problem that I have some followers and I want to send a direct message with image to all followers but I didn't get a way to do that.
I study whole documentation but can't find a way to do that.
My code is here:
NSString *strUrl = #"https://api.twitter.com/1.1/direct_messages/new.json";
NSURL *url = [NSURL URLWithString:strUrl];
strUrl = nil;
NSMutableDictionary *parameters = [NSMutableDictionary new];
[parameters setValue:#"name" forKey:#"screen_name"];
[parameters setValue:#"123456" forKey:#"user_id"];
[parameters setValue:#"sending text" forKey:#"text"];
// Creating a request.
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodPOST
URL:url
parameters:parameters];
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://www.greenuplawnandsprinklers.com/uploads/design_sample_landscape.jpg"]];
[request addMultipartData:imageData
withName:#"media[]"
type:#"image/jpeg"
filename:#"image.jpg"];
imageData = nil;
[request setAccount:twitAccount];
url = nil;
parameters = nil;
// Perform the request.
[request performRequestWithHandler:^(NSData *responseData,NSHTTPURLResponse *urlResponse,NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
// Check if we reached the rate limit.
if ([urlResponse statusCode] == 429)
{
NSLog(#"Rate limit reached");
return;
}
if(LOGS_ON) NSLog(#"TwitterFriendModel-->shareMagazineTitle-->error = %#",error);
// Check if there is some response data.
if (responseData)
{
NSError *error = nil;
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];
NSLog(#"dictionary = %#",dictionary);
dictionary = nil;
}
});
}];
}
I saw all other similar question/answers on stackoverflow but I didn't get a way to send direct message with image to followers.
Please don't consider this question as duplicate and try to resolve my problem. I will appreciate your every clue.
