在实现Facebook SSO的同时，调用facebook ios sdk的注销功能不会清除用户凭据，下次不要求登录。

While implementing facebook SSO, calling logout function of facebook ios sdk is not clearing user Credentials and it does not ask to login next time.

推荐答案

我使用Graph Api .....

I Used Graph Api.....

- (IBAction)loginButtonPressed:(id)sender {

    NSString *client_id = @"dsfgdgfgfgdfgvdfg";

    //alloc and initalize our FbGraph instance
    self.fbGraph = [[FbGraph alloc] initWithFbClientID:client_id];

    //begin the authentication process.....
    [fbGraph authenticateUserWithCallbackObject:self andSelector:@selector(fbGraphCallback:) 
                         andExtendedPermissions:@"user_photos,user_videos,publish_stream,offline_access,user_checkins,friends_checkins"];
}


- (void)logOutButtonPressed {

    NSLog(@"logout");

    fbGraph.accessToken = nil;
    NSHTTPCookie *cookie;
    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    for (cookie in [storage cookies])
    {
        NSString* domainName = [cookie domain];
        NSRange domainRange = [domainName rangeOfString:@"facebook"];
        if(domainRange.length > 0)
        {
            [storage deleteCookie:cookie];
        }
    }
