经过一周的研究，我无法解决这个错误:

发生 SSL 错误，无法与服务器建立安全连接。

_kCFStreamErrorCodeKey=-9802
NSErrorFailingURLStringKey=https://graph.facebook.com/v2.5

我还启用了钥匙串(keychain)共享。

我想我已经尝试了在互联网上找到的所有解决方案，但仍然没有成功。

如有任何帮助，我们将不胜感激。

Answer 1

所以在我认为我找到了错误的答案之后。

我正在使用 https 从 graph api 加载个人资料图像，它应该通过 http 加载。

例子:

https://graph.facebook.com/facebook_user_id/picture?type=large

应该是

http://graph.facebook.com/facebook_user_id/picture?type=large

请注意 https 协议(protocol)中缺少 s，这是关键区别。
