Authorization failed Error Domain=WebKitErrorDomain Code=101 "(null)

[Allansk2]

Hi, all
I have a view controller trying to login linkedin and post. But I couldn't get login, have the error message "Authorization failed Error Domain=WebKitErrorDomain Code=101 "(null). Really frustrated, hoping someone could help me! Thanks.

Here is my code
ViewController.h

import <UIKit/UIKit.h>

import "LIALinkedInApplication.h"

import "LIALinkedInHttpClient.h"

@interface ViewController : UIViewController

@Property (nonatomic, strong) LIALinkedInHttpClient *client;

• (IBAction) linkedInClicked:(id)sender;
• (void)requestMeWithToken:(NSString *)accessToken;

@EnD

ViewController.m

import "ViewController.h"

@interface ViewController ()

@EnD

@implementation ViewController

• (void)viewDidLoad
  {
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.

  LIALinkedInApplication *application = [LIALinkedInApplication applicationWithRedirectURL:@"http://www.google.com" clientId:@"" clientSecret:@"" state:@"something" grantedAccess:@[@"r_fullprofile", @"rw_nus", @"w_share"]];
  self.client = [LIALinkedInHttpClient clientForApplication:application presentingViewController:nil];

}

• (IBAction) linkedInClicked:(id)sender { // Login into the account
  [self.client getAuthorizationCode:^(NSString *code) {
  [self.client getAccessToken:code success:^(NSDictionary *accessTokenData) {
  NSString *accessToken = [accessTokenData objectForKey:@"access_token"];
  [self requestMeWithToken:accessToken];
  } failure:^(NSError *error) {
  NSLog(@"Quering accessToken failed %@", error);
  }];
  } cancel:^{
  NSLog(@"Authorization was cancelled by user");
  } failure:^(NSError *error) {
  NSLog(@"Authorization failed %@", error);
  }];
  }
• (void)requestMeWithToken:(NSString *)accessToken {
  [self.client GET:[NSString stringWithFormat:@"https://api.linkedin.com/v1/people/~?oauth2_access_token=%@&format=json", accessToken] parameters:nil success:^(AFHTTPRequestOperation *operation, NSDictionary *result) {
  NSLog(@"current user %@", result);
  } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
  NSLog(@"failed to fetch current user %@", error);
  }];
  }
