除了来自用户的小消息简介（“消息”参数）之外，每个参数都会正确发布。为什么这部分帖子没有显示在 facebook 中？我设置的参数错误吗？请查看这张图片，看看我说的是帖子的哪一部分： https ://skitch.com/hahmadi82/8uecw/brenton-joynin

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                                       [NSString stringWithFormat:@"%@ has invited you (%@) to enjoy an offer at %@ on %@", [nameArray objectAtIndex:0], [facebookNameArray objectAtIndex:i], spotString, timeChosenString], @"name",
                                                       domain, @"link",
                                                       [NSString stringWithFormat:@"%@ (%@)", offerString, peopleString], @"caption",
                                                       @"Going out? Use JoynIn to grab amazing offers from local bars, clubs, and restaurants. All you need to bring is friends!", @"description",
                                                       titleChosen.text, @"message",              
                                                       nil];
                        [facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/feed/",[facebookUIDArray objectAtIndex:i]] andParams:params andHttpMethod:@"POST" andDelegate:self];

您的 Facebook 会话有效吗？用 if 语句询问：

     if (facebook isSessionValid) {
NSLog (@"Working fine..."); // it might also be better to place the post method in here and put an else statement to open a alert where it says error or something like that
}

如果没有....检查你的方法，比如

handleOpenURL 和 fbDidLogin

在那里登录，看看是否被调用....如果没有，我有一个非常相似的问题......我会指导你完成

所以我的问题是我应该在 App Delegate 中声明 Facebook 变量......看这个..这是你应该做的手表：

     - (void)viewDidLoad
   {
fbAppDelegate = (NerdfeedAppDelegate *)[[UIApplication sharedApplication] delegate]; 
[[fbAppDelegate facebook] authorize:nil];// or wherever you wanna put it...
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
   }

   -(IBAction)post {

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                                   [NSString stringWithFormat:@"%@ has invited you (%@) to enjoy an offer at %@ on %@", [nameArray objectAtIndex:0], [facebookNameArray objectAtIndex:i], spotString, timeChosenString], @"name",
                                                   domain, @"link",
                                                   [NSString stringWithFormat:@"%@ (%@)", offerString, peopleString], @"caption",
                                                   @"Going out? Use JoynIn to grab amazing offers from local bars, clubs, and restaurants. All you need to bring is friends!", @"description",
                                                   titleChosen.text, @"message",              
                                                   nil];
                    [fbAppDelegate.facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/feed/",[facebookUIDArray objectAtIndex:i]] andParams:params andHttpMethod:@"POST" andDelegate:self];



   }

应用代理.h：

    @interface AppDelegate : UIResponder <UIApplicationDelegate, FBSessionDelegate,    FBDialogDelegate, FBLoginDialogDelegate, FBRequestDelegate> 

   {

  Facebook *facebook;

  }


  @property (strong, nonatomic) UIWindow *window;
  @property (strong, nonatomic) Facebook *facebook;

应用代理.m：

      static NSString *kAppID;
      - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
 return [facebook handleOpenURL:url];
   }

    - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [facebook handleOpenURL:url];
 }
  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{ 
  kAppID = [[NSString alloc] initWithString:@"//app id"];
   // ....
   facebook = [[Facebook alloc] initWithAppId:kAppId andDelegate:(id)self.viewController];
      [facebook setSessionDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
      if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) {
      facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
      facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }

return YES;
   }


- (void)fbDidLogin {

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
[defaults synchronize];    
       }

  -(void)fbDidLogout {


// Remove saved authorization information if it exists
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) {
    [defaults removeObjectForKey:@"FBAccessTokenKey"];
    [defaults removeObjectForKey:@"FBExpirationDateKey"];
    [defaults synchronize];
   }
  }

首先，“怎么来”是孩子们说的。大声笑对不起。其次，这是发布到另一个用户的提要。所以你应该检查他们的墙，而不是你的墙。

我相信你必须包括描述。这是我们使用的代码。似乎您的代码应该可以工作。您还应该检查以确保您的 %@ 格式化程序中有正确的 Facebook ID。

NSString *message = NSLocalizedString(@"FACEBOOK_INVITE_MESSAGE", nil);
NSString *link = @"http://www.facebook.com/trivialapp";
NSString *description = NSLocalizedString(@"FACEBOOK_INVITE_DESCRIPTION", nil);
NSString *picture = @"http://trivi.al/Content/images/icon72.png";
NSMutableDictionary *tParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                message,     @"message",
                                link,        @"link",
                                description, @"description",
                                picture,     @"picture", nil];

[facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/feed", [playerDict objectForKey:@"id"]] 
                      andParams:tParams
                    andHttpMethod:@"POST"
                    andDelegate:self];

如果您的意思是使用帖子对话框发布消息实际上那是不可能的，我遇到了同样的问题，我在 Facebook 文档中找到了这个

该字段旨在供用户表达自己。预先填写此字段会削弱用户语音的真实性。
