FBSDKShareDialog cancels when it should post

Question

I create a FBSDKShareDialog in code

- (void)shareWithFacebookDialog;
{  
  FBSDKShareLinkContent* content = [[FBSDKShareLinkContent alloc] init];
  content.c         


        

Answer 1

This happened to me when I tried to call the method right after login.

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    [login logInWithPublishPermissions:@[@"publish_actions"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
        if (error || result.isCancelled) {

        } else {
            [self shareWithFacebookDialog];
        }
    }];

It works if I just call it without logging in (should already have valid token).

if ([FBSDKAccessToken currentAccessToken]) {
    [self shareWithFacebookDialog];
}

For Facebook SDK v4.5+, try this:

Objective-C

FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:@"http://developers.facebook.com"];
[FBSDKShareDialog showFromViewController:self withContent:content delegate:self];

Swift

let content = FBSDKShareLinkContent()
content.contentURL = URL(string: "http://developers.facebook.com")
FBSDKShareDialog.show(from: self, with: content, delegate: self)

Answer 3

replace your code with this

- (void)shareWithFacebookDialog;
{  
    FBSDKShareLinkContent content = [[FBSDKShareLinkContent alloc]init];
    content.contentURL = [NSURL URLWithString:@"https://www.google.com"];
    content.contentTitle = @"ContentTitle";
    content.contentDescription = @"ContentDescription";
    [FBSDKShareDialog showFromViewController:self
                                 withContent:content
                                    delegate:self];
}

tell me if it works.

I had the same problem: Facebook SDK share always returns sharerDidCancel

My error was in the AppDelegate method:

here is a link with the solution http://jitu1990.blogspot.it/2015/05/share-with-facebook-from-ios-app.html

And here is the code

- (BOOL)application:(UIApplication *)application openURL:(NSURL* )url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {   
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                      openURL:url sourceApplication:sourceApplication annotation:annotation];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [FBSDKAppEvents activateApp];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    return [ [FBSDKApplicationDelegate sharedInstance] application :application
             didFinishLaunchingWithOptions:launchOptions]
  }
