Error Domain=LISDKErrorAPIDomain Code=400 "(null)" UserInfo={LISDKAuthErrorAPIResponse=}

Please find the below code which I am using in the application for sharing the contents.

- (IBAction)postOnLinkedin:(id)sender {

    if ([LISDKSessionManager hasValidSession]) {

        [self postOnLinedln];
    }

    else {

      [LISDKSessionManager createSessionWithAuth:[NSArray 
      arrayWithObjects:LISDK_BASIC_PROFILE_PERMISSION, 
      LISDK_EMAILADDRESS_PERMISSION, LISDK_W_SHARE_PERMISSION, nil]
         state:@"some state" showGoToAppStoreDialog:YES

          successBlock:^(NSString *returnState) {

              [self postOnLinedln];
          }

          errorBlock:^(NSError *error) {

            [self showAlert:error.localizedDescription];
          }
      ];
   }
 }

- (void)postOnLinedln {

    NSString *url = @"https://api.linkedin.com/v1/people/~/shares";

    NSString *payload = [NSString stringWithFormat:@"{\"comment\":\"Hello\","
                         "\"content\":{ \"title\":\"Title\","
                         "\"description\":\"%@\","
                         "\"submitted-url\":\"\","
                         "\"submitted-image-url\":\"\"},"
                         "\"visibility\":{ \"code\":\"anyone\"}}", self.description];

    if ([LISDKSessionManager hasValidSession]) {

        [[LISDKAPIHelper sharedInstance] postRequest:url stringBody:payload
                                             success:^(LISDKAPIResponse *response) {

           // do something with response                                                     
          dispatch_sync(dispatch_get_main_queue(),^{

             [self showAlert:@"Posted successfully"];                                                         
          });
      }

      error:^(LISDKAPIError *apiError) {

           // do something with error                                                       
           dispatch_sync(dispatch_get_main_queue(),^{

               [self showAlert:apiError.description];
           });
       }];
     }

    else {

        [self showAlert:@"No Valid session Linkdln"];
    }
}

As I have also gone through the developer portal of LinkedIn for resolving the issue but not getting any help on that.

Solution

  • Actually you do not passed the characters in the description field which is more than 256 which mentioned in the linkedin guideline.
