Linked in Share not working in my app

Question

Hi I want share text in LinkedIn through my app. My code is below here...

This method when I click the btn linkedIn share..

 - (void)linkedBtnEvent
    {
    if(oAuthLoginView != nil) {

        oAuthLoginView.delegate = nil;
        oAuthLoginView = nil;
    }

    oAuthLoginView = [[OAuthLoginView alloc] initWithNibName:nil bundle:nil];
    oAuthLoginView.delegate=self;

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(loginViewDidFinish:)
                                                 name:@"loginViewDidFinish"
                                               object:self.oAuthLoginView];

    [self presentViewController:self.oAuthLoginView animated:YES completion:nil];
}

This are the method to handle share after login..

-(void) loginViewDidFinish:(NSNotification*)notification
{
    [[NSNotificationCenter defaultCenter] removeObserver:self];

    [self profileApiCall];
}

- (void)profileApiCall
{
    NSURL *url = [NSURL URLWithString:@"https://api.linkedin.com/v1/people/~"];
    OAMutableURLRequest *request =

                                    consumer:oAuthLoginView.consumer
                                       token:oAuthLoginView.accessToken
                                    callback:nil
                           signatureProvider:nil];

    [request setValue:@"json" forHTTPHeaderField:@"x-li-format"];

    if ( profile )
    {
        NSLog(@"%@", [[NSString alloc] initWithFormat:@"%@ %@",
                      [profile objectForKey:@"firstName"], [profile objectForKey:@"lastName"]]);
    }

You need to add "rw_nus" in "scope". This only permit the app to share updates... This is your mistake otherwise all your code correct man..

- (void)requestTokenFromProvider
{
    OAMutableURLRequest *request = 
            [[[OAMutableURLRequest alloc] initWithURL:requestTokenURL
                                             consumer:self.consumer
                                                token:nil   
                                             callback:linkedInCallbackURL
                                    signatureProvider:nil] autorelease];

    [request setHTTPMethod:@"POST"];   

    OARequestParameter *nameParam = [[OARequestParameter alloc] initWithName:@"scope"
                                                                       value:@"r_fullprofile+r_contactinfo+r_emailaddress+r_network+r_basicprofile+rw_nus"];
    NSArray *params = [NSArray arrayWithObjects:nameParam, nil];
    [request setParameters:params];
    OARequestParameter * scopeParameter=[OARequestParameter requestParameter:@"scope" value:@"r_fullprofile r_contactinfo r_emailaddress r_network r_fullprofile rw_nus"];

    [request setParameters:[NSArray arrayWithObject:scopeParameter]];

    OADataFetcher *fetcher = [[[OADataFetcher alloc] init] autorelease];
    [fetcher fetchDataWithRequest:request
                         delegate:self
                didFinishSelector:@selector(requestTokenResult:didFinish:)
                  didFailSelector:@selector(requestTokenResult:didFail:)];    
}

Replace this is in your oAuthloginView.m

You can use a great lib for LinkedIn sharing: https://www.cocoacontrols.com/controls/linkedin-share

or directly from GitHub: https://github.com/pmilanez/MIS-Linkedin-Share

It is covered with MIT License and can be used in commercial project as well.

Hope this helps.
