iphone - How to post an image to a LinkedIn account using Objective-C code on iOS?

Question

I am able to post the comment to LinkedIn but not able to post the image. This is the code for posting the comment:

  NSURL *url = [NSURL URLWithString:@"http://api.linkedin.com/v1/people/~/shares"];
  OAMutableURLRequest *request = 
        [[OAMutableURLRequest alloc] initWithURL:url
                                        consumer:self.consumer
                                           token:self.accessToken
                                        callback:nil
                               signatureProvider:nil];
  NSString *postedStr = self.textView.text;
  NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys:
                                [[NSDictionary alloc] 
                                 initWithObjectsAndKeys:
                                 @"anyone",@"code",nil], @"visibility", 
                                postedStr, @"comment", nil];
  [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
  NSString *updateString = [update JSONString];
  [request setHTTPBodyWithString:updateString];
  [request setHTTPMethod:@"POST"];
  OADataFetcher *fetcher = [[OADataFetcher alloc] init];
  [fetcher fetchDataWithRequest:request
                        delegate:self
               didFinishSelector:@selector(postUpdateApiCallResult:didFinish:)
                 didFailSelector:@selector(postUpdateApiCallResult:didFail:)];    
    // [self.view addSubview:linkedinView];
   [request release];

Any suggestion really appreciated!

try this bellow code may be its help you:-

-(void)postUpdateHERE
{
  NSURL *url = [NSURL URLWithString:@"http://api.linkedin.com/v1/people/~/shares"];
  OAMutableURLRequest *request =
  [[OAMutableURLRequest alloc] initWithURL:url
                            consumer:[self getConsumer]
                               token:self.accesstoken
                            callback:nil
                   signatureProvider:nil];

  NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys:

                    [[NSDictionary alloc]
                     initWithObjectsAndKeys:
                     @"anyone",@"code",nil], @"visibility",

                    @"comment goes here", @"comment",
                    [[NSDictionary alloc]
                     initWithObjectsAndKeys:
                    @"description goes here",@"description",
                    @"www.google.com",@"submittedUrl",
                      @"title goes here",@"title",
                    @"http://economy.blog.ocregister.com/files/2009/01/linkedin-logo.jpg",@"submittedImageUrl",nil],@"content",
                    nil];
  [request setValue:@"json" forHTTPHeaderField:@"x-li-format"];
  [request setValue:@"application/xml" forHTTPHeaderField:@"Content-Type"];
  NSString *updateString = [update JSONString];
  [request setHTTPBodyWithString:updateString];
  [request setHTTPMethod:@"POST"];
  OADataFetcher *fetcher = [[OADataFetcher alloc] init];
  [fetcher fetchDataWithRequest:request
                 delegate:self
        didFinishSelector:@selector(postUpdateApiCallResult:didFinish:)
          didFailSelector:@selector(postUpdateApiCallResult:didFail:)];

}

i found this from bellow stackover flow answer:-

Can't share using OAuth Starter Kit for LinkedIn

EDIT:-

For TamilKing comment reply. you can get image URL of you currunt Location using Google API. First you need to get you currunt Location Image Like:-

NSString *staticMapUrl = [NSString stringWithFormat:@"http://maps.google.com/maps/api/staticmap?markers=color:red|%f,%f&%@&sensor=true",lat, log,@"zoom=12&size=114x116"];    //That above staticMapURl NSlog is :http://maps.google.com/maps/api/staticmap?markers=color:red|1.282130,103.803131&zoom=12&size=114x116&sensor=true

That given you current Location image for example:-

Now you have to convert this above NSString to NSURL like

NSURL *mapUrl = [NSURL URLWithString:[staticMapUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 

and use this url that you want to share in to LinkedIn. hope that helps you.
