ios - 将 Facebook SDK 更新到 3.5 后无法打开事件 session

Question

将 Facebook SDK 更新到 3.5 后，尝试执行 openActiveSessionWithReadPermissions 时操作失败。下面是打开 session 和处理回调的代码片段:

[FBSession openActiveSessionWithReadPermissions:@[@"email", @"user_hometown", @"user_location", @"user_birthday"]
                                   allowLoginUI:YES
                              completionHandler:
 ^(FBSession *session,
   FBSessionState state, NSError *error) {
     switch (state) {
         case FBSessionStateCreatedTokenLoaded:
         case FBSessionStateOpenTokenExtended:
         case FBSessionStateOpen:
         {
             completion(TRUE);
             break;
         }
         case FBSessionStateClosed:
         case FBSessionStateClosedLoginFailed:
             completion(FALSE);
             [FBSession.activeSession closeAndClearTokenInformation];
             break;
         default:
             break;
     }
 }];

我最终遇到 FBSessionStateClosedLoginFailed 情况，并得到如下 FBSKLog:

FBSDKLog: Cannot use the Facebook app or Safari to authorize, fb123456789012345 is not registered as a URL Scheme

我有同样的问题(Facebook SDK 3.5.1)

我的 Facebook URL 方案位于 Info.plist URL 方案中的第 1 项。 通过将其移至项目 0 解决了问题。
