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

问题

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.

You may need to do more, but for sure you'll need to set the length...

[request setValue:[NSString stringWithFormat:@"%d", updateString.length] forHTTPHeaderField:@"Content-Length"];
