Iphone 如何向朋友发帖'；时间轴

我正试图贴到朋友的墙上，但没有成功

错误：

错误Domain=com.facebook.sdk Code=5“无法执行该操作 已完成。（com.facebook.sdk错误5。）“UserInfo=0xa799fa0 {com.facebook.sdk:HTTPStatusCode=403， sdk:ParsedJSONResponseKey=( { 正文={ 错误={ 代码=200； message=“（#200）此应用程序已禁用向其他用户发布提要故事”； 类型=OAutheException； }; }; 代码=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;
}

- (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)fbSessionInvalidated{
}

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

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

在PostViewController中发布到朋友时间线的代码：

-(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;
}

- (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];
}

查找，或作为替代方法。

我使用此代码时出错：

- (void)showFeedDialog {
    // Put together the dialog parameters
    NSMutableDictionary *params =
    [NSMutableDictionary dictionaryWithObjectsAndKeys:
     @"MY_APP_ID", @"app_id"

     @"USER_ID", @"to",

             NSLog(@"Error publishing story.");
         } else {
             if (result == FBWebDialogResultDialogNotCompleted) {

你查过了吗，朋友墙的帖子被贬低了什么？？？那么，你是说我不能发到朋友墙，只要把他作为标签或者贴到我自己的墙上就行了？！是的，你不能，在那个链接上自己读。如果你需要的话，你可以使用其他方法。我不能通过FBWebDialog发到朋友那里吗？是的，你可以使用，它已经在备选方案列表（提要对话框）中列出。是的，我看到了，但我的意思是，没有将他作为标记提及，比如发送带有“to”和用户ID的参数，我得到的是“无法发布到用户的墙”删除“redirect_uri”参数。请尝试使用其他用户，因为他可能将“谁可以在您的时间线上发布？”设置为“只有我”。请发布完整的错误，如果有的话。检查用户“谁可以在你的时间线上发布？”？-设置为Friends，我是Friends。重定向\u url已删除。仍然出现错误，无法捕获错误，错误显示在对话框本身上：哇！！问题在于NSDictionary对象之间的逗号。但现在我无法在对话框中包含消息“message”参数似乎不起作用很好，但为什么您需要

message

参数？此对话框不支持该参数。因为我希望用户只需按“发送/发布”，并且要在好友墙上发布的文本将来自应用程序中的文本字段。我不能这样做吗？是否有支持该参数的对话框？
