【问题描述】：

FBSDKShareDialog 返回到您的应用时（用户创建帖子后）的回调方法是什么？

这是我必须创建的对话框：

-(IBAction)post:(id)sender
    FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = [NSURL URLWithString:self.spinShareURL];
    content.contentDescription=@"#spin";
    self.fromFacebook = true;

    [FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];

我在某处读到有回调

-(void)dialogDidComplete:(FBSDKShareDialog *)dialog
 

但这对我不起作用。

【问题讨论】：

委托将在FBSDKSharingDelegate 上完成，我认为，而不是在FBSDKShareDialog 上，您将nil 放在哪里：developers.facebook.com/docs/reference/ios/current/protocol/…

【参考方案1】：

我在以下页面找到了解决方案：

这是我的最终代码：

-(IBAction)post:(id)sender
    FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = [NSURL URLWithString:self.spinShareURL];
    content.contentTitle= [NSString stringWithFormat: @"%@'s spin", self.username];
    content.contentDescription=@"#spin";
    self.fromFacebook = true;

    [FBSDKShareDialog showFromViewController:self withContent:content delegate:self];

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results

    NSLog(@"returned back to app from facebook post");
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil
                                                    message:@"Posted!"
                                                   delegate:self
                                          cancelButtonTitle:nil
                                          otherButtonTitles:nil];
    [alert show];
    double delayInSeconds = 1.0;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void)
        [alert dismissWithClickedButtonIndex:0 animated:YES];
    );


- (void)sharerDidCancel:(id<FBSDKSharing>)sharer

   NSLog(@"canceled!");


- (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error

    NSLog(@"sharing error:%@", error);
    NSString *message = @"There was a problem sharing. Please try again!";
    [[[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];

【讨论】：

我正在使用这些委托功能，分享成功后它在sharerDidCancel中，@scientiffic你可以指导我
