iOS 的 FBSDKShareDialog 回调

Question

当 FBSDKShareDialog returns 返回到您的应用程序时（在用户创建完 post 之后），FBSDKShareDialog 的回调方法是什么？

这就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];

}

我在某处看到有一个回调

-(void)dialogDidComplete:(FBSDKShareDialog *)dialog{
 }

但这对我不起作用。

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];
}
