使用此类代码创建Facebook对话框时
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: apiKey, @"api_key", nil];
[facebook dialog:@"stream.publish" andParams:params andDelegate:self];
是否可以使用会话?
我成功地在用户的帖子墙上发布帖子,但是如何允许用户注销? 此外,当我尝试访问当前用户信息时,我收到此错误。
{
error = {
message = "An active access token must be used to query information about the current user.";
type = OAuthException;
};
}

我在viewDidLoad
中创建了Facebook对象_facebook = [[Facebook alloc] init];
我有一个tableView。当用户点击某个条目时,会弹出一个包含3个选项的操作表
1发送电子邮件
在Facebook上分享
3从Facebook注销:它应该只在用户登录时存在,但是目前它在那里并且它有效。 我用
[_facebook logout:self];
而且方法
- (void)fbDidLogout is called.
当用户点击“在Facebook上分享”时,将运行此代码
SBJSON *jsonWriter = [SBJSON new];
NSDictionary *actionLinks = [NSArray arrayWithObjects:
[NSDictionary dictionaryWithObjectsAndKeys:
@"Some text", @"text",
@"http://try.com",@"href", nil], nil];
NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
@"is using...", @"name",
@"It's an app….", @"caption",
@"Download!", @"description",
@"http://ituneslink", @"href",
nil];
NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
API_KEY, @"api_key",
@"Message", @"user_message_prompt",
actionLinksStr, @"action_links",
attachmentStr, @"attachment",nil];
[_facebook dialog:@"stream.publish" andParams:params andDelegate:self];
[jsonWriter release];
在viewDidLoad中,我也尝试使用
_facebook.accessToken = [[NSUserDefaults standardUserDefaults] stringForKey:@"AccessToken"];
_facebook.expirationDate = (NSDate *) [[NSUserDefaults standardUserDefaults] objectForKey:@"ExpirationDate"];
_permissions = [[NSArray arrayWithObjects: @"read_stream", @"offline_access",nil] retain];
if ([_facebook isSessionValid] == NO) {
[_facebook authorize:API_KEY permissions:_permissions delegate:self];
}
放入fbDidLogin:
[[NSUserDefaults standardUserDefaults] setObject:_facebook.accessToken forKey:@"AccessToken"];
[[NSUserDefaults standardUserDefaults] setObject:_facebook.expirationDate forKey:@"ExpirationDate"];
但永远不会调用fbDidLogin。

我解决了使用FB october api(虽然我没有找到11月的解决方案)。

看起来这是权限问题,请尝试:
[facebook setPermission:@"offline_access"];
