ios - Facebook 帖子的权限是 "Only me"使用 FBWebDialogs

Question

我想将文本和链接从 iOS 应用发布到用户时间轴。我复制并粘贴 FBWebDialogs 示例。

问题 1:该帖子出现在我的时间轴中，但权限是“只有我”，而不是 friend 或公众。

问题 2:结果对象 (FBWebDialogResult) 为 nil。日志出现在我的控制台中。NSLog(@"User canceled story publishing.");

问题 3:预览框的权限是“只有我”，即使我将其设置为公开

我的 Facebook 页面的附加设置:

这是我的代码:

[FBWebDialogs presentFeedDialogModallyWithSession:nil
                                       parameters:params
                                          handler:
 ^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
     if (error) {
         // Error launching the dialog or publishing a story.
         NSLog(@"Error publishing story.");
     } else {
         if (result == FBWebDialogResultDialogNotCompleted) {
             // User clicked the "x" icon
             NSLog(@"User canceled story publishing.");
         } else {
             // Handle the publish feed callback
             NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
             if (![urlParams valueForKey:@"post_id"]) {
                 NSLog(@"User canceled story publishing.");
             } else {
                 NSString *msg = [NSString stringWithFormat:
                                  @"Posted story, id: %@",
                                  [urlParams valueForKey:@"post_id"]];
                 [[[UIAlertView alloc] initWithTitle:@"Result"
                                             message:msg
                                            delegate:nil
                                   cancelButtonTitle:@"OK!"
                                   otherButtonTitles:nil]
                  show];
             }
         }
     }
 }];

我的应用的设置页面默认是“only me”。我不希望我的所有用户都在此处更改此设置。

Answer 1

我的天哪。我挣扎了一整天，没有任何进展。我一提出问题就找到了解决方案。

问题是我复制了不合适的示例代码。我更改为 [FBSession openActiveSessionWithPublishPermissions] 并解决了问题。

这是我使用的登录代码。我的帖子现在可以公开了。

- (void)buttonRequestClickHandler:(id)sender {
// FBSample logic
// Check to see whether we have already opened a session.
if (FBSession.activeSession.isOpen) {
    // login is integrated with the send button -- so if open, we send
    //  [self sendRequests];
    NSLog(@"Login in facebook");
} else {

      NSArray *permission = [NSArray arrayWithObjects:@"publish_actions", nil];
    [FBSession openActiveSessionWithPublishPermissions:permission defaultAudience:FBSessionDefaultAudienceEveryone allowLoginUI:YES completionHandler:^(FBSession *session,
                                                      FBSessionState status,
                                                      NSError *error) {
                                      // if login fails for any reason, we alert
                                      if (error) {
                                          UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                                          message:error.localizedDescription
                                                                                         delegate:nil
                                                                                cancelButtonTitle:@"OK"
                                                                                otherButtonTitles:nil];
                                          [alert show];
                                          // if otherwise we check to see if the session is open, an alternative to
                                          // to the FB_ISSESSIONOPENWITHSTATE helper-macro would be to check the isOpen
                                          // property of the session object; the macros are useful, however, for more
                                          // detailed state checking for FBSession objects
                                      } else if (FB_ISSESSIONOPENWITHSTATE(status)) {
                                          // send our requests if we successfully logged in
                                          NSLog(@"Login in facebook");                                          }
                                  }];
}
