iOS Facebook SDK MessageDialog error 202

Question

I am trying to set up Facebook sharing with FBSDK in my iOS app.

I have been reading the documentation here, and currently have

[FBSDKShareDialog showF         


        

Answer 1

I had to login and then Post , that is how it worked :

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];


[login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
{

    if (error)
    {
    // Process error
    }
    else if (result.isCancelled)
    {
        // Handle cancellations
    }
    else
    {
        FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
        content.contentURL = [NSURL URLWithString:@"https://developers.facebook.com/"];

        FBSDKMessageDialog *messageDialog = [[FBSDKMessageDialog alloc] init];
        messageDialog.delegate = self;
        [messageDialog setShareContent:content];

        if ([messageDialog canShow])
        {
            [messageDialog show];
        }
        else
        {
            // Messenger isn't installed. Redirect the person to the App Store.
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/en/app/facebook-messenger/id454638411?mt=8"]];
        }

    }
}];

and the Share Delegate :

- (void)sharer:(id)sharer didCompleteWithResults:(NSDictionary *)results
{
    NSLog(@"didCompleteWithResults");
}

- (void)sharer:(id)sharer didFailWithError:(NSError *)error
{
    NSLog(@"didFailWithError ::: %@" , error);
}

- (void)sharerDidCancel:(id)sharer
{
    NSLog(@"sharerDidCancel");
}

Edit:

[messageDialog canShow] returns NO on the iPad, works fine on iPhone

Posted the issue on Facebook Developers forum.
