我正在尝试使用Facebook iOS游戏教程中的代码进行分享。对话框弹出,我指定的图像和文本都存在,但是当我点击“发送”时,加载栏出现,但没有加载,然后我被重定向到我的应用程序。控制台上没有打印错误,应用程序也没有崩溃。
当我进入Facebook检查是否已发布消息时,我得到以下信息:
“哎呀,出了些问题。发布状态时出了问题。我们已记录该错误并将加以处理。”
我在之前的应用程序中使用过这个代码,它完全正常工作。我已经更新了plist中的Facebook ID、Facebook显示名称和URL方案。
以下是代码: FacebookHandler类(从Facebook教程派生)

这似乎是Facebook应用程序的问题。在未安装Facebook的设备上尝试时,我会被要求登录,然后成功发布。但是,如果已安装了Facebook,则无法发布。
