仅在iOS 9中FBSDKGraphRequest FBSDKGraphRequestConnection返回错误

Question

这是iOS 9.0.1的登录成功。

这是iOS 9 iPhone的登录失败。

在iOS 9 iPhone中我有这个警告：

sdk更新从此处解析1.8.5和Facebook到4.6：https://developers.facebook.com/docs/ios/ios9

我该怎么做才能解决这个问题？

Facebook登录是使用PFFacebookUtils logInInBackgroundWithReadPermissions：

  NSArray *permissions = [NSArray arrayWithObjects:@"email",@"user_friends", nil];
[PFFacebookUtils logInInBackgroundWithReadPermissions:permissions block:^(PFUser *user, NSError *error)
 {
     if (!user) // The user cancelled the Facebook login
     {
         NSLog(@"Uh oh. The user cancelled the Facebook login.");
     }
     else if (user.isNew) 
     {

     }
     else if (user) // the user is exist at DB
     {

     }
     else if (error)
     {
     }
 }];
