自动登录Facebook

Question

如果有人在iphone中登录了fb，请在我的应用中自动登录facebook。多数民众赞成，如果facebook a / c已经在任何应用程序或iphone上登录，我不会要求用户提供凭据。

Answer 1

试试这段代码。

- (void)fbDidLogout
{
    //NSLog(@"facebook did logout");

    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];
        }
    }
    //////NSLog(@"facebook did logout");
    [self showLoggedOut:YES];
    logoutButton.hidden=YES;

}
