FbConnect：同时发布在用户的墙上和新闻源中？

Question

我使用下面的代码登录使用FbConnect到FB：

- (IBAction)loginButtonClicked:(id)sender { 

    facebook = [[Facebook alloc] initWithAppId:@"355949667779777" andDelegate:self]; 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
     && [defaults objectForKey:@"FBExpirationDateKey"]) { 
     facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"]; 
     facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"]; 
    } 
    if (![facebook isSessionValid]) { 
     NSArray *permissions = [[NSArray alloc] initWithObjects: 
           @"user_likes", 
           @"read_stream", 
           @"publish_stream", 
           nil]; 
     [facebook authorize:permissions]; 
     [permissions release]; 
    } 

} 

然后我用下面的代码发布到用户的墙：

- (IBAction)postToWallPressed:(id)sender { 

     SBJSON *jsonWriter = [[SBJSON new] autorelease]; 

     // The action links to be shown with the post in the feed 
     NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: 
                 @"Get Started",@"name",@"http://m.facebook.com/apps/hackbookios/",@"link", nil], nil]; 
     NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; 
     // Dialog parameters 
     NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
             @"Testing VB", @"name", 
             @"Integrating Facebook in VB.", @"caption", 
             @"VB is a voice morphing app for videos.", @"description", 
             @"http://www.google.com/", @"link", 
             @"http://www.freeimagehosting.net/newuploads/49ncw.png", @"picture", 
             actionLinksStr, @"actions", 
             nil]; 

     [facebook dialog:@"feed" andParams:params andDelegate:self]; 


} 

该帖子的发布用户的墙罚款，但它不会在新闻源中发布。

我在这里做错了什么？

链接，最近更新的Facebook API：https://github.com/facebook/facebook-ios-sdk

您正在使用Facebook的更新API？因为在最近更新的Facebook API中，您根本不需要使用JSONWriter和ActionLinks。因此，请尝试升级您的API并按照Facebook网站提供的Facebook教程进行操作。

你也可以尝试这个代码。它对我来说非常合适。我正在使用ARC（自动引用计数）。所以如果你想自己添加它。不要忘记您添加APP_ID在代码和.plist文件太

-(void)buttonPressed:(id)sender{ 
facebook = [[Facebook alloc] initWithAppId:@"YOUR_APP_ID" andDelegate:self]; 

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
     if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) { 
      facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"]; 
      facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"]; 
     } 
if (![facebook isSessionValid]) { 
NSArray *permissions = [[NSArray alloc] initWithObjects: 
           @"user_likes", 
           @"read_stream", 
           @"publish_stream", 
           nil]; 
    [facebook authorize:permissions]; 
}else{ 
[self postWall]; 
} 
// Pre 4.2 support 
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { 
    return [facebook handleOpenURL:url]; 
} 
- (void)fbDidLogin { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"]; 
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"]; 
    [defaults synchronize]; 
    [self postWall]; 
} 
-(void)postWall{ 

    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
        @"https://developers.facebook.com/docs/reference/dialogs/",@"link", 
            @"http://fbrell.com/f8.jpg",@"picture", 
            @"Facebook Dialogs",@"name", 
            @"Reference Documentation",@"caption", 
            @"Using Dialogs to interact with users.",@"description", 
            @"Facebook Dialogs are so easy!",@"message", 
            nil]; 

    [[self facebook] dialog:@"feed" andParams:params andDelegate:self]; 

}
