- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    if ([PFLinkedInUtils shouldHandleUrl:url]) {
        return [PFLinkedInUtils application:application openURL:url sourceApplication:sourceApplication annotation:annotation];
    }
    return YES;
}

Example

[Parse initializeWithConfiguration:
     [ParseClientConfiguration configurationWithBlock:
      ^(id<ParseMutableClientConfiguration>  _Nonnull configuration) {
          configuration.applicationId = @"PARSE_APP_ID";
          configuration.clientKey = @"PARSE_CLIENT_KEY";
          configuration.server = @"PARSE_SERVER_URL";
      }]];

[PFLinkedInUtils initializeWithRedirectURL:@"LINKEDIN_REDIRECT_URL"
                                      clientId:@"LINKEDIN_CLIENT_ID"
                                  clientSecret:@"LINKEDIN_CLIENT_SECRET"
                                         state:@"LINKEDIN_STATE"
                                 grantedAccess:@[@"r_basicprofile", @"r_emailaddress"]
                      presentingViewController:nil];

[PFLinkedInUtils logInWithBlock:^(PFUser *user, NSError *error) {
    NSLog(@"User: %@, Error: %@", user, error);
    
    [PFLinkedInUtils.linkedInHttpClient GET:@"LINKEDIN_API_URL" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Response JSON: %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
    }];
