Question

我正试图发布到朋友的墙上，没有任何成功

错误：

错误Domain = com.facebook.sdk代码= 5“操作不能完成。（com.facebook.sdk错误5.）“UserInfo = 0xa799fa0 {com.facebook.sdk：HTTPStatusCode = 403， com.facebook.sdk：ParsedJSONResponseKey =（ { body = { error = { 代码= 200; message =“（＃200）此应用程序禁用向其他用户发布Feed故事”; type = OAuthException; }; }; code = 403; }）

LoginViewController中的登录过程：

-(IBAction)facebookButtonPressed:(id)sender {    
    [facebook authorize:[self permissions]];
}

- (NSArray *)permissions {
    static NSArray *pms;
    if (pms == nil) {
        pms = [[NSArray alloc] initWithObjects: @"user_photos", @"user_location", @"user_birthday",
               @"friends_birthday", @"friends_location", @"friends_photos", @"user_relationships",
               @"publish_actions", @"publish_stream", nil];
    }
    return pms;
}

在PostViewController中发布到朋友的时间轴的代码：

- (void)postToFriendWall:(NSString *)userId {
    facebook = [[Facebook alloc]initWithAppId:APP_ID andDelegate:self];

    if (![facebook isSessionValid]) {
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        [facebook setAccessToken:[defaults objectForKey:FB_ACCESS_TOKEN]];
        [facebook setExpirationDate:[defaults objectForKey:FB_EXPIRATION_DATE]];
    }

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *defaultWish = [defaults objectForKey:[NSString stringWithFormat:@"%@%@", DEFAULT_WISH, [defaults objectForKey:FB_USER_ID]]];
    NSString *defaultImage = [defaults objectForKey:[NSString stringWithFormat:@"%@%@", DEFAULT_IMAGE, [defaults objectForKey:FB_USER_ID]]];

    if (defaultImage == nil && defaultWish == nil) {
        [self showAlertViewWithTitle:@"Post wasn't sent" message:@""];
        return;
    }

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
    [params setObject:defaultWish forKey:@"message"];
    if (![defaultImage isEqualToString:@"none"])
        [params setObject:[UIImage imageNamed:defaultImage] forKey:@"picture"];

    [facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/feed", userId] andParams:params andHttpMethod:@"POST" andDelegate:self];
}

- (void)request:(FBRequest *)request didLoad:(id)result {
}

- (void)fbDidLogin {
}

- (void)fbDidExtendToken:(NSString*)accessToken expiresAt:(NSDate*)expiresAt {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:FB_ACCESS_TOKEN];
    [defaults setObject:[facebook expirationDate] forKey:FB_EXPIRATION_DATE];

    [defaults synchronize];
}

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error {
    NSString *errorDescription = [error description];
}

- (void)request:(FBRequest *)request didReceiveResponse:(NSURLResponse *)response {
}

- (void)fbDidNotLogin:(BOOL)cancelled{
}

- (void)fbDidLogout{
}

- (void)fbSessionInvalidated{
}

- (void)fbDialogLogin:(NSString *)token expirationDate:(NSDate *)expirationDate {
}

- (void)fbDialogNotLogin:(BOOL)cancelled {
}

Answer 1

截至2013年2月6日，您无法使用该图表方法发布到朋友的时间轴。

请阅读：https://developers.facebook.com/roadmap/completed-changes/

寻找feed Dialog，user mentions tagging或Open Graph Actions作为替代方案。

我使用此代码并收到错误：

- (void)showFeedDialog {
    // Put together the dialog parameters
    NSMutableDictionary *params =
    [NSMutableDictionary dictionaryWithObjectsAndKeys:
     @"MY_APP_ID", @"app_id"
     @"feed", @"method"
     @"USER_ID", @"to",
     @"try", @"caption",
     @"https://develo‌pers.facebook.com/docs/reference/dialogs/", @"link",
     @"try link", @"name",
     @"http://fbrell.com/f8.jpg", @"picture",
     @"Using%20Dialogs%2‌0to%20interact%20with%20users.", @"description",
     @"https://mighty-lowlands-638‌1.herokuapp.com/", @"redirect_uri",
     nil];

    // Invoke the dialog
    [FBWebDialogs presentFeedDialogModallyWithSession:nil//[FBSession activeSession]
                                           parameters:params
                                              handler:
     ^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
         if (error) {
             // Case A: Error launching the dialog or publishing story.
             NSLog(@"Error publishing story.");
         } else {
             if (result == FBWebDialogResultDialogNotCompleted) {
                 // Case B: User clicked the "x" icon
                 NSLog(@"User canceled story publishing.");
             } else {
                 // Case C: Dialog shown and the user clicks Cancel or Share
                 NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
                 if (![urlParams valueForKey:@"post_id"]) {
                     // User clicked the Cancel button
                     NSLog(@"User canceled story publishing.");
                 } else {
                     // User clicked the Share button
                     NSString *postID = [urlParams valueForKey:@"post_id"];
                     NSLog(@"Posted story, id: %@", postID);
                 }
             }
         }
     }];
}
