如何在Facebook iPhone 6中共享带有图像和描述的链接

Question

    UIImage *image = [UIImage imageNamed:@"attachment_blank.png"];
    FBSDKSharePhoto *photo = [FBSDKSharePhoto photoWithImage:image userGenerated:NO];
NSDictionary *properties = @{
                               @"og:type": @"app:recipe",
                               @"og:title": @"Sample Recipe",
                               @"og:description": @"",
                               @"og:url": @"http://samples.ogp.me/216213502062059",
                               @"og:image": @[photo]
                           };
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];
FBSDKShareAPI *shareAPI = [[FBSDKShareAPI alloc] init];
[shareAPI createOpenGraphObject:object];

The submission guidelines speak about a "user generated photos" permission that doesn't seem to be available anywhere in the app settings, or anywhere else in the documentation. Is that still required? Is there a similar permission for images?

Answer 1

You can try this method to share an image with link. The image you want to share should need to be on server(ie you need to use link of an image ) Note:- You must have an "publish_actions" permission from facebook app

Below method is shown using the facebook sdk 4.3

In .h file

#import <FacebookSDK/FacebookSDK.h>
@property (strong, nonatomic) FBRequestConnection *requestConnection;

In .m file

-(IBAction)facebookBtn:(id)sender{
    if (!FBSession.activeSession.isOpen) {
    // if the session is closed, then we open it here, and establish a handler for state changes
    [FBSession openActiveSessionWithReadPermissions:@[@"public_profile", @"email", @"user_events", @"user_location", @"publish_actions"]
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session,
                                                      FBSessionState state,
                                                      NSError *error) {
                                if (error)
                                {
                                    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:NSLocalizedString(@"Error", nil) message:error.localizedDescription delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];

                                          if (error.code!=2)
                                          {
                                              [alertView show];
                                          }

                                      }
                                      else if (session.isOpen)
                                      {

                                          [FBRequestConnection startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                                              [self requestCompleted:connection forFbID:@"me" result:result error:error];
