FBSDKSharing Callback not returning results

Question

In my iOS app, I have a Facebook share button, which opens up a FBSDKShareDialog:

-(IBAction)post:(id)sender{

    FBSDKShareLinkContent *content = [[FBSDKShareL         


        

Answer 1

The solution is to check in the delegate method sharer:didCompleteWithResults: if user has Facebook installed as @Adam Eisfeld suggested :

- (void)sharer:(id)sharer didCompleteWithResults:(NSDictionary *)results{

    // check if user has facebook app installed
    NSURL *fbURL = [NSURL URLWithString:@"fb://"];
    // there is no facebook app installed
    if (![[UIApplication sharedApplication] canOpenURL:fbURL]){
        // facebook is not intalled check the keys
        if (results.allKeys.count !=0){
            // success you can get your post ID
        }else {
            // if resutlst.allKeys == 0 means user press Done button 
        }
    } else {
        // the share is successfully and facebook is installed
    }
}

and from iOS9.0 do not forget to add in your .plist file LSApplicationQueriesSchemes key (an array of strings) and add fb check this post for more details.
