【问题描述】：

我正在使用以下代码通过 FbConnect 登录到 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];
    

然后我使用以下代码发布到用户的墙上：

- (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];

帖子在用户的墙上正常发布，但没有在新闻源中发布。

我在这里做错了什么？

【参考方案1】：

新更新的 Facebook API 的链接： https://github.com/facebook/facebook-ios-sdk

您是否使用更新的 Facebook 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。

Facebook API 教程链接： https://developers.facebook.com/docs/mobile/ios/build/

您也可以试试这个代码。它对我来说非常有效。我正在使用 ARC（自动引用计数）。所以如果你想自己添加它。不要忘记在代码和.plist文件中添加你APP_ID

-(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];

【讨论】：

我认为我们不能......但我们甚至可以尝试获取本地图像的 url 并使用该 url 代替那个。可能会起作用..检查后通知我..
