我正在尝试邀请 Facebook 中的用户试用我的 iOS 应用程序（尚未在商店中，尚未完成）。

我使用 facebook API 对用户进行身份验证，然后尝试使用以下代码：

- (void)shareWithFriends:(id)sender
{
    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@"Invite Friends"
                          message:@"If you enjoy using this app, would you mind taking a moment to invite a few friends that you think will also like it?"
                          delegate:self
                          cancelButtonTitle:@"No Thanks"
                          otherButtonTitles:@"Tell Friends!", nil];
    [alert show];
}

- (void)alertView:(UIAlertView *)alertView
didDismissWithButtonIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        // User has clicked on the No Thanks button, do not ask again
        NSLog(@"Chitty user says he doesn't wanna share");
    } else if (buttonIndex == 1) {
        // User has clicked on the Tell Friends button
        [self performSelector:@selector(sendRequest) withObject:nil afterDelay:0.5];
    }
}

- (void)sendRequest {
    // Display the requests dialog

    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
    [FBWebDialogs presentRequestsDialogModallyWithSession:nil
                                                  message:[NSString stringWithFormat:@"Try this app, brah!"]
                                                    title:nil
                                               parameters:params
                                                  handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                                      if (error) {
                                                          // Case A: Error launching the dialog or sending request.
                                                          NSLog(@"Error sending request.");
                                                      } else {
                                                          if (result == FBWebDialogResultDialogNotCompleted) {
                                                              // Case B: User clicked the "x" icon
                                                              NSLog(@"User canceled request.");
                                                          } else {
                                                              NSLog(@"Request Sent.");
                                                          }
                                                      }}];


}

但是，当我选择要向其发送邀请的用户然后点击发送时。什么都没发生。我确实收到“请求已发送”。通过 NSLog 但我的朋友没有收到它。

有任何想法吗？

我注意到通知消息只出现在 Android/iOS 的 Facebook 应用程序中，但是网络用户看不到它，我希望它不是 Facebook 的实现？此外，为了确保您的邀请成功发送，您必须解析 resultURL 查询。

NSDictionary *parameters = @{@"to":@""};

[FBWebDialogs presentRequestsDialogModallyWithSession:nil
                                                      message:SL_FB_INVITE_DESCRIPTION
                                                        title:SL_FB_INVITE_TITLE
                                                   parameters:parameters
                                                      handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
         {
             if(error)
             {
                 NSLog(@"Some errorr: %@", [error description]);
                 UIAlertView *alrt = [[UIAlertView alloc] initWithTitle:@"Invitiation Sending Failed" message:@"Unable to send inviation at this Moment, please make sure your are connected with internet" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
                 [alrt show];
                 [alrt release];
             }
             else
             {
                 if (![resultURL query])
                 {
                     return;
                 }

                 NSDictionary *params = [self parseURLParams:[resultURL query]];
                 NSMutableArray *recipientIDs = [[[NSMutableArray alloc] init] autorelease];
                 for (NSString *paramKey in params)
                 {
                     if ([paramKey hasPrefix:@"to["])
                     {
                         [recipientIDs addObject:[params objectForKey:paramKey]];
                     }
                 }
                 if ([params objectForKey:@"request"])
                 {
                     NSLog(@"Request ID: %@", [params objectForKey:@"request"]);
                 }
                 if ([recipientIDs count] > 0)
                 {
                     //[self showMessage:@"Sent request successfully."];
                     //NSLog(@"Recipient ID(s): %@", recipientIDs);
                     UIAlertView *alrt = [[UIAlertView alloc] initWithTitle:@"Success!" message:@"Invitation(s) sent successfuly!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
                     [alrt show];
                     [alrt release];
                 }

             }
         }
                                                  friendCache:nil];

- (NSDictionary *)parseURLParams:(NSString *)query
{
    NSArray *pairs = [query componentsSeparatedByString:@"&"];
    NSMutableDictionary *params = [[[NSMutableDictionary alloc] init] autorelease];
    for (NSString *pair in pairs)
    {
        NSArray *kv = [pair componentsSeparatedByString:@"="];

        [params setObject:[[kv objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
                   forKey:[[kv objectAtIndex:0] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    }

    return params;
}

它始终取决于您的应用所在的平台。例如：如果您有一个只能在手机上使用的应用程序，受邀的朋友将只能在他们的手机上看到请求，而不会在 facebook.com 上看到。如果您在 facebook.com 上也有一个画布应用程序，它也会出现在 facebook.com 上。

您可以在有关应用程序发送的请求的“接收体验”[1] 的文档中了解更多信息。

你怎么知道你的请求没有到达其他用户？您必须知道他们不会收到任何通知，他们可以通过以下链接访问它：

您的应用中必须有一个 Facebook 应用作为具有画布页面的平台。然后用户将收到通知。

你什么时候填充参数？

我知道如果您发送一个空白的 Facebook 用户名作为收件人，FB API 会发送一个已完成的操作
